Hi guys! This is my first fanfic, and really I'm just trying this out. No flames please, only constructive criticism please! Hope you enjoy the story!

Percy POV

To say that Percy was surprised, would be an understatement.

Poseidon –his very powerful Olympian dad, by the way- had just come knocking on his cabin door, offering Percy a once-in-a-lifetime chance to stay with him in Atlantis for 2 weeks of his summer break.

Now naturally, Percy was ecstatic. He could spend 2 weeks bonding with his awesome dad, while Annabeth was working on designing Olympus, and Sally and Paul, were chilling on the beaches of Montauk. But of course, who can forget his immortal half-brother –and quite a pain in the butt at that- Lord Triton. Then there was also his step-mother Lady Amphitrite, who just so happened to hate his guts. Then again, there was his endearing Cyclopes half-brother Tyson…

As if sensing his thoughts, Poseidon stated "Amphitrite has openly agreed to spend some time with you, and is almost looking forward to it! Triton, on the other hand, might be slightly difficult…" Percy looked taken back, but considering he had nothing to do all summer except participate in camp activities, it wouldn't be too bad to hang out with Tyson, pick fights with Triton and bond with his dad and stepmom.

"Great dad! Then I guess I'll be coming." Percy said nodding slowly. Then, though, a sudden thought hit Percy.

"Wait, what about Zeus's law?" "Ah, well, if Nico can stay with Hades in the Underworld, then why can't my son stay with me in Atlantis?" Poseidon replied slyly.

Percy's eyebrows scrunched together, highly doubting his dad's logic. "Um, dad? I don't think it works like that." "Bah, Thalia and Jason were just given chances to stay with Zeus, no way in Hades, is that going to slip by me!" Poseidon exclaimed.

Percy nodded gratefully before turning to his cabin. "Well, if you don't mind waiting ten minutes for me to pack, then we can head off together." Poseidon nodded before sauntering into his cabin, obviously pleased that his favorite son would be staying with him for a while.

Ten minutes later, Percy held onto Poseidon's arm, his free arm holding his bag, as they teleported to the throne room of Atlantis. As soon as the appeared, Percy keeled over, his poor body not used to teleporting. When he stood up beside his father, he immediately noticed that they had company. Standing before him was the whole family, including Tyson.

He had a second to brace himself before Tyson bounded over to him and gave him a hug that almost broke his ribs. "Brother! It has been so long! I have missed you so much! How is Annabeth?" Tyson asked while Percy spat out the taste of flannel and smoke.

"Hey big guy! Annabeth's good, she misses you. You should come up to camp more often!" He told his little brother.

After greeting Tyson, Percy immediately turned to Lady Amphitrite and bowed. "Hello my Lady Amphitrite!" he said meekly, expecting a disapproving sneer like the last time he saw her. Instead, her beautiful features turned into a smile, light radiating off her face. She had chosen to be in her human form, so her double tail was morphed into two legs and she had on an elegant sea blue dress, and her brown, wavy locks of hair, swished in and out of Percy's view. On her head was a silver crown and her sea blue eyes seemed to radiate with kindness. "Percy. Welcome to Atlantis. It's going to be a pleasure having you here!" Amphitrite said smiling. He was about to reply when he heard a snort, whether it was full of disbelief, malice or pure humor, Percy didn't exactly know.

He turned his head towards the snort to see a merman with pale blue skin and long black hair tied into a ponytail. He had two tails -symbolizing royalty- which were swirling and were a mesmerizing green. He was wearing a blue polo shirt and his green eyes matched Percy's except they were filled with dislike and hostility. "Lord Triton" Percy said letting slight sarcasm seep into his words. "Perseus" he replied. Percy flinched at the use of his full name, but decided to let it go since Triton probably didn't know. Triton smirked smugly at Percy whose thought track immediately changed. Of course Triton knew that his full name annoyed Percy, as he was just trying to irritate Percy.

Percy gritted his teeth in annoyance. He was not going to be lured into Triton's traps. Then Percy surprised everyone by smiling at Triton and replying stoically "I prefer Percy".

Before Triton could reply, however, Poseidon cut in.

Poseidon POV

When he had brought Percy to Atlantis, he was expecting some type of backlash from Triton. He was, no doubt, surprised when Percy managed to rein his anger in line. Poseidon knew, though as Percy smiled, he was furious on the inside. His eyes were what gave him away, and no doubt Triton had noticed it to.

Percy's usually calm sea green eyes were dark and cloudy, giving an illusion of hurricanes and storms blowing inside his pupils.

That's when Poseidon had decided to step in and interrupt before things got out of hand.

"Come Percy, I'll take you to your room where you can settle in." Poseidon said cutting in between Percy and Triton's argument. Percy's eyes lit up before following Poseidon to the doors.

Poseidon followed Percy's gaze and saw, in satisfaction, as it set on Poseidon's throne at the far end of the hall. It was huge and made of marble, but it was different shades of blue and gave an illusion of flowing water and shifting waves. It was next to Amphitrite's throne which was smaller and sea-green.

Eventually though, they were out of the throne room and heading down the hallway where Poseidon came to a gentle stop. "Ah, we've arrived. This is your room Percy." Poseidon watched in amusement as Percy's jaw dropped and his eyes widened.

The room was a sea green like Percy's eyes, and it was huge. There was a single bed with a blue popping headboard and a baby blue desk positioned further away, accompanied by a black chair. Percy's room was air and was water-free, so any merman or mermaids (including servants), had to change into human form before walking in. There was a big balcony overlooking the twinkling lights of Atlantis, which could be hidden from view, by two sea green curtains. The walls were decorated with pictures and items representing Percy's quests, including Tartarus, which he shrunk away from.

"Well? Do you like it?" Poseidon asked, worry evident in his face as Percy looked around for so long. "Dad.. I love it!" he shrieked pulling his dad into a bear hug. Poseidon chuckled and ruffled his hair before saying "The room next to your is Triton's, and the one next to his, is Tyson's." He continued seeing Percy's approving nod. "On your other side is mine and Amphitrite's room." Percy smiled at that. Suddenly a voice cut in from behind Poseidon, near the door. "Although, why father wants to have your room closest to his, I'll never know." Triton said as both father and son spun around to face Triton. Percy smiled, not giving in to his goading, though it looked more grim then genuine. "Percy you have twenty minutes until dinner is served, I suggest you settle in before father changes his mind and sends you back to the surface" Triton said smirking. Poseidon noticed how Percy's fist clenched and then unclenched in an attempt to calm himself down. He decided to step in before Percy's anger won out and he lashed out at a god.

"Triton, that's enough. Go to your room and leave Percy alone. He has enough to deal with other then your pointless goading." Poseidon said angrily. He swallowed down the satisfaction of seeing Triton's shocked and outraged face, after all Poseidon hated it when people where rude to his favorite son. Although he would never tell that to Triton. Then Triton would probably blow up Mt. Vesuvius again. He really could go without a moody and angry immortal son right now. Poseidon was dragged out of his thoughts to see Triton swim furiously out of the room. Poseidon winked at Percy and left the room too, the last thing in his memory before getting ready for dinner, being a sheepish Percy, rubbing the back of his neck adorably.

Well, that's it guuysss! Hope you liked it and the second chapter should be coming up soon!
