A/N: Hey you guys! I just wanted to say thank you so, so, so much for checking out my new fan fiction. I also wanted to warn you about something. In this story Nico and Bianca aren't Hades' son and daughter. I know they are in the really Percy Jackson series, but to make this fan fiction work better I made it to where Bianca and Nico are Maria di Angelo's children and they are Hades' stepchildren. I just thought I would clear that up and i hope it doesn't bother anyone. I just did it to make the story work a lot better. Anyways, thank you once again for checking out my fan fiction and I would love it if you guys could leave a favorite on this story or a comment. Have a wonderful, amazing, beautiful day, my friends! :3

Summary: Percy knows that love is a weird concept. Look at his parents for example: remarried after seven years of divorce. No one could have counted on it. As far as weird love stories go he is no stranger. In fact he is the main star in a twisted attraction of his own. With his uncle Hades remarried and two new cousins he never expected to fall for one of them. He never expected the temptation of Nico di Angelo.

Rating: M for mature. Sexual content and mature language.

Pairing: Percy Jackson and Nico di Angelo

Welcome To Temptation
Percy's POV
Chapter 1: You Might Be So Lucky

I was sure of one thing and one thing alone: A family reunion is always depressing as hell. The hours spent recollecting old stories that you've heard for the thousandth time, eating those random foods made by family members who you barely knew, having to worry about poison in the punch because most of the people who showed up would rather kill you than hear you whine- Yeah, it's not the most practical way to spend a Sunday evening. It's almost worse than those stupid assembles they do at school- You know those ones were everyone sits around for a couple hours, blocking out every word, and using the "Drugs Are For Fools" booklets as makeshift hand fans. Almost as bad.

Or it could be compared to group therapy sessions that they do on Thursdays in the school's science lab. If you have never been to one then I say kudos to you, sir. Almost 97% of our school district either has mental issues, anger problems, a drug addiction, obsessions with another person, or they are just messed up in general. I probably fit into the mental/emotional issues category. Most people stop dead in their tracks when they hear that prince Percy Jackson has problems. Everyone has similar reactions: Wow, Jackson really does have mental issues. I figured it was just a joke.

Being one of the lowest on our school's food chain brings upon a lot of harassment or rumors, but when word gets around that some of them are actually true- Well, it's just a field day for those who have nothing better to do than fuck up someone else's life.

The group of us in therapy hasn't changed in a while rather than expanded. There are the Stoll brothers who were placed there after rigging the girl's bathroom with smoke bombs. Principle D. (Short of Dysious) automatically made a decision after that: They had an obvious behavior problem which resulted in them being placed in our history teacher Chiron's therapy group. Next there was Clarisse who had anger issues. We've lost count of how many times she's broken desks, dented lockers, and tried to drown someone in the public restrooms. There's also Grover (who smokes recreation weed way more than he should), Juniper (a nervous wreck caused by her boyfriend A.K.A. Grover's weed smoking), Selina (OCD over her appearance), and last but not least me. I'd be joking if I said I was the normal one in our group. For the past few years my step father Gabe (or smelly Gabe considering on who you ask) has been abusive to me and my mother both. No one will ever know how much I laughed when our neighbors called the police over domestic violence and had his ass thrown in jail. I just wished someone would have done it sooner.

Either way, a few years of curses and slaps finally got my biological father named Poseidon's attention. He left my mother about seven years ago around my tenth birthday because the two of them couldn't get along. In my opinion if they would have calmed down and stopped fighting over trivial things their marriage would have been smooth sailing, but that's beside the point. He came to visit us over one weekend and two months later I was hearing wedding bells and we once again had a perfect family. It's been like that for three months now. Funny how life turns out.

Along with my father's return came the family reunions again. If my memory hasn't failed me I still have vivid images of the gathering when I was a young child. There was always a long table set up in whoever's front lawn, piled with different foods that mainly consisted of something that you would find at a picnic (don't you hate it when you have to eat picnic food, but you're not at a picnic. What's the point?). The place was always crawling with relatives that I didn't remember or talk too often. Usually there were only two or three people that I really knew. Let's just say the ones I did know wished they didn't know me. If they (by some miracle) happened to like me than I usually didn't bother with them or talk to them often because I dion't like them. Once again, it's funny how life turns out.

My dad pulled into the long driveway in front of my Uncle Hades' house at 3:24. I pretended to fiddle with my loose shirt button to kill time. I wish that I could have found a more clever way to put this off, but who can deny one of the classic responses. Everyone gives it a try every once in a while, so why shouldn't I? My father caught on to this immediately before turn towards my mother.

"Sally….Can you get him?"

"Huh," My mother said as she clambered from the front seat. She stopped ruffling through her purse as she glanced back at me. "Percy, come on. Get out of the car."

"Fine…" I claimed with an unyielding nod and toss of my hair. God, I hate having bangs. I shifted from side to side, the thick seat covers squeaking as I climbed out of the backseat. God, I hate leather seat covers.

"Come on, Percy. Let's get moving!" My father called as he led me forward. God, I hate it when he acts like I can't take care of myself. I hate it when he tells me what to do. I hate coming to visit people. I hate family reunions. I hate everything!

"Do I have to go? Can't I just stay in the car?" I questioned innocently, masking my aggravation behind a façade of fake optimism. I was cut off by the gentle, low grumble of my stomach.

Have you ever been getting ready for a Christmas dinner or a Thanksgiving dinner or something along those lines? Have you ever gotten ready, been dressed, ready to move when suddenly your stomach starts yelling at you like a dying Humpback Whale? Yeah, I hate it when that happens. The worst part of the situation is that if you have a mother like mine then you know they won't let you eat anything before you leave. It all like "You'll spoil your dinner." Or "We'll be eating in a few minutes. You don't need anything now." I guess those phrases aren't just for holidays anymore. Seems like adults are expending the market on when it is wrong to stuff your face. Apparently it's not appropriate timing to chow down before a family reunion either so I didn't get any breakfast or lunch. Thanks so much, mom.

"Well, if you stay in the car then you won't get any food. It sounds like you're awfully hungry." My mother came up beside me, placing a tender hand on my shoulder as she let me forward. With a sigh of resignation I followed.

Walking through the gate into the back yard I immediately headed towards the snack table. Of course it was the usual wooden tables pulled together in a line and plastic table cloth with a floral pattern. I don't know why I expected anything different from Uncle Hades considering he's divorced and can barely make a burrito by himself. When I was seven my uncle married a woman named Persephone, and by the time I was eight they were divorced. Of course it was expected. My uncle was a hot head and his wife was a pampered princess. It wouldn't have worked out very well and the whole family knew it, but we just didn't voice our opinions. Who were we to throw in our claims in his love life?

Moving on from the crappy attempt at a picnic atmosphere, the food actually threw me for a loop. Dancing away from the usual plates of egg salad, hot dogs, hamburgers, and sandwiches poorly cut into flowers, there was actual food lying out like a buffet. It was plates and plates of expertly made barbecue, strange noodles that I didn't know what it was, fresh fruit, and more and more things that I didn't know what they were. I'm not a culinary expert, but…Hell, I didn't have any idea what the fuck most of the food was! It definitely wasn't made by my uncle. Of course the dinner looked a little strange, but I wasn't going to refuse it before taste testing.

I grabbed a strange looking fruit popsicle…thing and poured some juice into a Dixie cup before turning away from the table and entering the crowd before me. I could identify a few people who whisked around the back yard, trampling over the newly cut grass and strewing clumps of unattached plants everywhere, but most of them looked pretty different than seven years prior. Names whirled around in my mind like a mini tornado: Apollo, Artemis, Aphrodite, Hephaestus, Ares, Hermes, Athena, Thalia, Jason, Zeus, Hera, and a few more. The moment I realized my cousins were at the reunion, they noticed me as well. I knew I was off to a good start when the first person I talked to was the only one who partially liked me or maybe my day was peaking early and the rest would be a living hell. Either way, oh well.

Since my mother and father got divorced I haven't really seen any family member on my father's side. In fact I was completely cut out considering dad never bothered to tell me when they were coming over or took me to visit them or…I don't know…bothered to come see me himself. Nope, nothing bitter there, but…still i missed my cousins and, to some extent, both my uncles. So seeing Thalia for the first time in seven years was like a breath of fresh air.

"Hey, Dumbass! Long time no see! You haven't changed at all, have you?" Thalia came up, ruffling my hair with one hand as though I was a child. Well, technically the last time I saw her I was a child, but nether less I was still offended.

"Hey, Bitch! Long time no see to you, too!" I countered.

"Wow," The amusement her voice was nearly consuming. Looking Thalia up and down I couldn't believe how much she had changed. Instead of being the little girl running around in jeans and Hello Kitty t-shirts, long hair tied up in pigtails, she looked like she was caught somewhere between Goth and emo.

I expected jeans and a t-shirt, but instead Thalia was clad in a short skirt (one that probably sent her father into frenzy if the man is the same as he was seven years ago), a black tank top, and knee high boots. All of her hair had been hacked off in jagged points, sticking up like it was full of intentional cow licks. Fine streaks of electric blue adorn the black locks, a shade that matched her eyes perfectly. To be honest that was the only thing that stayed the same about her: Her electric blue eyes.

"I never knew you could be so bad, Percy! Cussing so crudely." Thalia leaned forward, shoving me back with a wicked smile.

"Thalia, Percy- don't speak like that." My father interrupted our conversation with a wave of his hand, trying his best to defuse the situation and our cursing before others took notice of our foul language.

"Don't bother with her, Poseidon," A voice came beside my father. I turned to see the boy who I had known since birth, Jason Grace, waving an exaggerated hand at his sister, trying his best to shoo her away as though she was a pesky fly, "She's been cursing like this ever since she knew what the words meant. Her vocabulary consists of inappropriate things and inappropriate things alone."

I looked Jason up and down with zeal, happy to have another (sort of) friend at the reunion. Jason was the opposite of his sister having light, blonde hair the trickled in front of his face like strings of liquid gold opposed to stringy black hair like Thalia. His skin was smooth and tan. His face was graceful yet strong. Curving along the bottom side of his lips was a snippy little scar, coming from a stapler he tried to swallow when he was younger. That day still vividly stands out in my mind due to the fact that I still have never found another person who could dent a metal staple with baby teeth as they tried to shove t down their throat.

The only thing that even resembled Thalia was Jason's blue eyes. Those perfect blue eyes that seem way too deep for his years and held a hint of sadness.

"Well, it shouldn't. Besides, Percy I need to talk to you for a moment." My father placed his hand on my shoulder as he begin to lead me away, but I rebuttal his action, standing my ground and refusing to move.

"I think I would rather stay here." I countered, "You know- here with Jason and Thalia."

"Percy…please…," He started again although he was quickly cut off by Thalia's jab into our conversation.

"Oh! Are you talking about the new family member!? Is that what you want to tell him about? " Thalia's voice rung through me like a strike of lightening, the words catching me completely off guard.

"Awwww…Don't tell me that Aunt Hera has gotten herself pregnant! We don't need a little one of her running around!" I cried obscenely, speaking the first thought that came into my mind. Thalia glanced over at me before bursting out. Her laughter was louder and more obscene that my own comment, concluding in bringing in more attention that the actual joke. Jason gave a snort of indignity, disapproving of his sister's behavior, but laughing in spite of himself.

"Percy….come here." My father's voice was etched with disapproval as he took my hand and pulled me to the side. Standing against the old white picket fence, my father looked at me up and down, not really saying anything, but shaking his head as though I was something disgusting.

"What?" I questioned, raising my arms in defense. I new insulting Hera probably pissed him off, but he didn't have to rip me over to the side in front of everyone. If you have ever done something as a child (broke something, screamed at someone, throw a tantrum, etc.) than you've probably had a parent yell at you or spank you and nothing could be worse than having them do that in public. This is the same kind of situation. I hated when someone in my family called me out in front of everyone. Hell, if my father actually wanted to punish me he should have made me sit in the car. In his mind that might have been taking away a privilege, but in my case it would have made my day.

"Listen Percy, I was hoping you could meet them and not have me explain this to you, but since me and you're mother have been divorced, Hades got remarried." Well, that's a shocker. I snorted at my father's words, looking at him in distaste.

"Well, that stings. Just because you and mom where divorced doesn't mean that I wasn't part of your family. You could have called and told me that once they got married. I mean how long ago did this happen. Four….five years ago?" I couldn't keep the hatred and loathing out of my voice. I loved my dad- everyone knew that, including him, but sometimes he just pissed me off. He treated me like during that time that my mother and him were divorced I wasn't his son anymore.

"Percy, calm down. It was five months ago. I would have invited you to the wedding, but I was afraid that being away from everyone for a while and seeing them then would be awkward for you," My father claimed, shaking his head as though he felt bad. I didn't believe it, "I wish I would have tried to keep you in touch with the family. I know it was the wrong thing to do, but now I'm trying. Maybe it's too late, but we have to give it a shot. Please, please, please don't offend anyone just yet. I think it's too early in the day for this."

"Fine," I murmured under my breath. To be honest I just wanted to end the conversation, "So, what's this girl's name, Hades new wife?"

"Her name is Maria di Angelo and she's not the one I wanted to tell you about. I think you'll get along with her alright or at least better than you got along with Persephone. She's nice, she's a great person, and she has a son and daughter that are around your age."

"Wait…what?"

"You have two new cousins to welcome to the family: Bianca and Nico di Angelo. The girl sixteen and I believe the boy is fourteen. I just wanted to warn you about them. I don't know how well you'll get along with either of them and I just want to make sure you don't insult them immediately."

"Dad," I cried indignity, shaking my head furiously, "You act like I'm just some bastard who smarts off to everyone."

"Watch your mouth!" He acknowledged instantly, answering the question as to why I could offend someone with three simple words. I may have a little trouble with vulgar language, but I doubt it's enough to make anyone pissed with me. It doesn't really matter what they think anyways. I don't believe I'll be changing any time soon.

By the time I meet Hades' new wife Maria I was way too pissed off and aggravated to bother trying my best to be nice. In general I'm probably a pleasant person- nice manners, an alright sense of humor, a good smile. It's not like I'm that bad, but after being sun burnt, annoyed by Thalia for a couple hours, and having to hear stories from Apollo about how great his life is… Well, it can really put a damper on my mood.

So, by the time this woman came sweeping out onto the patio and into the backyard I was already ready to go home, but despite my demands and pleas for the salvation of our family's car my father pulled me forward to introduce us. I was actually surprised by this woman- not really by how she acted, but how she looked. No matter how much I hated Hades ex-wife I would admit that Persephone was beautiful, yet she was nothing compared to Maria di Angelo. With tan skin, dark hair, and a skinny form she was definitely pretty. Not to mention the fact that she looked absolutely dazzling in her frilly, orange sundress.

"Hello, Poseidon! Nice to see you again. This must be your son Percy." She gave me a graceful smile before extending her hand. I know I should have been shaking her hand instead of analyzing her voice, but immediately I picked up on her accent. It took me a while to place it, but after a while I came to the conclusion that she was Italian. Taking her hand gently, actually being slightly nervous, I gave a pleasant nod.

"Nice to meet you, Percy. I've heard quite a lot about you." I'm sure have. It took all my power to not roll my eyes on instinct. I bet my father has said a lot about me- I'm rude, disrespectful, odd, awful, horrible, messed up in the head. I'm sure she's heard everything. (I know he's probably never said any of this, but my anger makes irrational thoughts. Oh well.)

I was about to say something along the lines of hello or nice to meet you too, but I was quickly interrupted by the sudden voice behind the woman.

"Mother!" The word was spoken softly, the voice sweet and kind despite the edge of discomfort. The clicking of shoes and light sound of breathing came next followed by the form that etched around the door to the patio, looking at us all as though she was a mouse surround by three hawks. All eyes on her.

Immediately I knew this was Bianca, Maria's daughter. She looked so much like her mother- just as beautiful with an even more feminine and shy appearance. Her silky dark hair brimmed out from her tan hat, a few strands tangled within the black bow around the brim. She was pretty and I knew eventually as she got older she would reach her mother's level of beauty. She was already on her way. If she wasn't my cousin I probably would have asked her out. It may sound a little strange or freakish, but who wouldn't deny a pretty girl.

"Oh, Bianca! Come here! I want you to meet Poseidon son- Percy Jackson." Maria declared my name in a regal manner, sounding as though I was a king or something. I could imagine myself as a king to be honest. My entire kingdom would probably crumble within a day or two, but for the time being we would all have a hell of a time.

"Hello." Bianca stated simply, shaking my hand before drawing back quickly. Despite her shyness and withdraw she looked me directly in the eyes, her face stern and clear as she gave a quaint smile. Within seconds her attention was taken away from me and put back to her mother. The way she flipped her attention in a split second, more focused and more determined than most people are in their entire life, showed intelligence and precision in this one moment.

"Nico won't leave his room." She once again stated simply.

"Oh…," Maria gave a smile of sorts, but it wavered way too quickly. She turned to me and my father with a look that asked for something- patience.

"Could you please excuse me for a moment? Or, if you wouldn't mind, try to help my son. He's just a little bit…how should I put this… shy." Maria said oddly, almost like she apologizing in advance.

I didn't bother asking what she meant by help, but I followed as she led the way inside, heading towards the stairs across from the kitchen. She looked back at me and gave a smile of gratitude before looking back up the steps.

"Nico, I have someone here that wants to meet you." Maria said tenderly before glancing up at the stairs as though she expected something (or someone). Rolling around the corner Maria called up the stairs, "Nico, come down stairs."

"No." The single word was spoken flatly although footsteps followed. I watched the boy trudge around the corner and towards his beaming mother. Maria grinned before placing her hands gently on Nico's shoulders, holding the boy in place as though he would bolt within a moment's notice.

I looked him up and down curiously, taking in his appearance and demeanor with one go. He was the complete opposite of his sister. Hell, to tell the truth he was more Goth than Thalia and that's saying something. He was wearing completely black, long bangs draped across his forehead and into dark, deep eyes. He had sadness within his expression. Or maybe he was just entirely sour.

"Nico, this is the boy I was telling you about- Poseidon's son Percy." Maria gave a brief introduction. The look she gave Nico was a little harsh and the true meaning within was spoken loud and clear: Say anything or do anything embarrassing and your life is over. I get that look a lot so I already know how to spot it a mile away.

The boy gave a slight huff before giving into his mother's accusing glare. With an extended hand he said the simplest…..scratch that, the most beautiful expression of human emotion that I have ever heard, "Hey. I'm Nico. I don't like you. You won't like me. This shit is overrated. I'm done here. Good fucking bye."

Without another word the boy turned on his heels, jogging quickly back up the stairs as his mother and sister shared concerned looks. To say the least I was as shocked as they were, but within that moment I decided on one thing: Nico di Angelo was already amazing.
