A/N: So… Does anyone know Bianca's age? I can't find a good source. I did try looking at the Wikia and at the book, but either it doesn't say or I didn't find it. I did get an page that says shes 14, though. Except, it also said Nico is 12 while the Wiki says he's 10 so…

Update: Found it in Titan's Curse. Thanks :) Nico is 10 and Bianca is 12

Chapter 1

I Meet Death's Little Champion

…

Can I keep him?

Percy Jackson was not having a good day, or a good week for that matter. First off, he'd learned that he wasn't human. Okay, so he was half human. Tomato, to-mato

That hasn't been bad. Okay, sure, being the son of Poseidon was a shock and learning that he had a big prophecy over his head hadn't been nice, but whatever. He could deal with it. He could deal with the way the campers had treated him afterwards, he could deal with the added pressure, the added expectations, no biggie.

Percy could honestly care less about his so called father.

He was a little pissed that he'd only been claimed as a last minute choice by his father to prevent a war, but whatever. Putting the weight of preventing World War III on the shoulders of a child must just be a thing Greek Gods did.

However, the one thing he could not and would not take standing down was his mother. Hades took her, Hades made him believe he had lost her, and there was no way in … well, Hades that Percy wasn't going to get her back.

At least, that was what he had been thinking before.

Now, though?

"Die, die, die!"

Percy was having far too much fun… Playing laser tag, that is. Team Blue for the win! Percy had been playing for a few rounds so far. His team was in the lead! Having Demigod instincts and reflexes was probably cheating, but whatever. Percy had his strengths and he was having fun using them since he usually wasn't allowed to play sports at school due to his 'destructive behavior'.

Percy took careful aim and fired at the little soldier that kept running across the field. Really? Then again, no one else who opened fire seemed to hit the brat- he was quick on his feet- but not as fast as Percy.

"Damn it!"

Percy blinked. He could have sworn… But, no, impossi-

"Nico, language!"

"But, but, Bianca-"

"'But, but, brother', language!"

"You curse too!"

"I'm the older sibling. I'm allowed to curse. Duh."

Percy couldn't help but laugh. That was his defeat as a stray shot managed to take him out. Percy, however, no longer cared about the game. Instead, he made his way down to the still bickering siblings

"Can you understand me?" Percy asked in Ancient Greek.

Both siblings whirled around.

"Duh. You're speaking plain en- hey! That's him! That's the guy! Let me at him, let me at him!"

Percy was shocked when the small boy, who couldn't be older than nine, tried to tackle him. Tried being the key word as the girl, his sister grabbed him from behind.

"Bianca, let me go! I'm gonna kick his ass! I'm… I'm… I'm gonna set Mythomagic monsters on him!"

"Nico, you can't attack random strangers!"

"He kept shooting me! Literally, for the last five games!"

"Well yeah, you kept running out into the middle of the field yelling battle cries." Percy couldn't help but interject.

The boy glared at him.

Dark messy hair, tan skin, small and tiny, fierce glare that actually managed to send shivers down Percy's spine. Considering he'd glared at Ares without a moment's hesitation, that was some feat.

However, as said little monster was currently being held back by his sister, Percy could only respond to the situation in one way.

"You are adorable!"

Nico blinked. Bianca blinked. Nico glanced up at Bianca.

"Now, can I hit him?"

Percy gave out a cry as he was pounced on by a child.

"My name's Percy," Percy smiled, holding his hand out.

They'd left the laser tag area and, of course, the virtual reality suits, so Percy was once more standing in his awesome new clothes, courtesy of the Lotus Casino. This place was awesome!

"I'm Bianca. That's Nico," the girl smiled and shook Percy's hand. Percy resisted the urge to snatch his hand away from hers. Hot! As in, burning hot. Silently, he wondered if the girl had a fever.

Now that Percy could actually see her face, he could tell that she was pretty. Freckles were splayed out around her face, she had gleaming dark eyes and olive skin just like her brother, and silky dark hair.

"So, are you guys Demigods too?" Percy smiled. They had to be Demigods. They'd understood his Greek, after all. Only Demigods understand Greek naturally like that.

Bianca gave him an odd look. "Demigods? What are you talking about?"

"Oh, oh! You mean like- like- like Heracles, like Perseus, like Achilles! Achilles only has 700 attack points but he has 3000 defense points, the highest of any non-God!" Nico interrupted, bouncing up and down repeatedly.

Percy was confused.

"Um… What?"

"Mythomagic! There are a few Demigods, but they're more like collectors cards since they don't show up too much. It's an awesome game they have here at the casino store!" Nico revealed, pulling out a deck of cards which had several mythological figures on them. Percy glanced at a few and snorted when he saw Zeus' bolts only did 600 damage. He seriously hoped the King of the Gods never learned of this. Knowing Zeus, the Sky God would rain down endless storms on whoever invented Mythomagic in the first place.

"Awesome. How do you play?"

And, just like that, Percy was distracted once more.

However, unlike the two boys, Bianca di Angelo was not one to get distracted easily. With a roll of her eyes, she smacked Percy upside the head.

"Ow!" Percy cried out. That girl had a mean punch. Percy would know. He met the bloody Minotaur. "What was that for?" he glared.

Nico blinked.

"Sis didn't knock you out? Is your head, like, made of stone?" Nico asked. Then, the child bounced again. Percy was seriously convinced Nico had an infinite supply of energy. "Oh, oh! Are you like Achilles! Do you have superskin? Is that why sis didn't knock you out like she did to that one guy that kept hitting on her, is that-"

"Nico!"

"What? I wanna tell the story!"

"Afterwards, Nico! Hold on," Bianca placated the child before turning to Percy, "Now… Demigods?"

Percy stared at her for several seconds before he remembered. This place was making him seriously woozy. Weird.

"Oh yeah, huh! Are you guys Demigods?" he asked, smiling. Looking back, Percy would realize that his long stay in the Hotel- even if he hadn't realized how long he'd stayed there- had affected his thinking and his sense of secrecy. At the moment, though, the twelve year old couldn't be bothered to care too much about details like that.

"What is a Demigod?" Bianca's eyes scrunched up in confusion.

Nico rolled his eyes.

"I already told you sis, it's the child of a Greek god and a human, duh," Nico extended the h with a pointed look at his sister.

"Quiet," Bianca whacked him.

"Ow!"

"What he said," Percy quickly replied, not wanting to be on the other side of that fist. That girl had hands of steel. Just what were they feeding her in this place?

Bianca turned to him and glared.

"Demigods aren't real. Greek gods aren't real."

"Yeah, they are, and you guys are obviously Demigods 'cause you can understand me when I speak like this." Percy argued.

Bianca froze.

"That… That wasn't English."

"No. Its Ancient Greek. All Demigods can understand it. It's hardwired into our brains," Percy informed the girl. He couldn't believe he was giving the Demigod speech so soon after it had been given to he himself. Come to think of it, why was Percy giving them this speech? He should get Annabeth to do it. She was way smarter than he was.

"We're Demigods… We're Demigods? What does that even mean?" as a girl who had been forced to grow up too fast so that she could take care of her little brother, Bianca di Angelo was freaking out.

Nico di Angelo, on the other hand…

"Cool! Do we get to breath underwater? Do we get to transform into random animals? Can we summon the dead, because that would be cool and I really want a zombie army!"

"Nico! This is serious!"

"I know! It's seriously cool!" Nico declared.

Bianca groaned. Then, she paused. A look of realization struck her. Then, the girl smiled.

"Wait a minute… This must mean one of our parents is obviously still alive, so whoever our Godly parent is, they're gonna have to step up and take care of us," the girl smiled, content at the thought of no longer being fully responsible for such a chaotic child like Nico.

In Bianca's defense, no girl her age should be practically raising a child when she herself was still a kid. She technically wasn't even a teenager yet.

Percy blanched. He really didn't want to get on Supergirl's bad side, but…

"It erm… Doesn't exactly work like tha-" Percy paused. The air around them became frigid and cold. Percy swore he saw the shadows around them thicken as Bianca turned to glare at him, her eyes glowing with a demonic tinge.

"I'll make it work like that!"

"Right, yeah, of course!" Percy, fearing for his survival, rapidly agreed. Were those hell flames he saw in the background? No, must just be his imagination, the floor looked just fine.

"So… You're a Demigod right? That means you have superpowers!" Nico interrupted. How that kid could smile while his sister was literally radiating darkness was beyond Percy.

Percy turned towards the little boy. "I can breath underwater. And I can talk to horses," he revealed.

"Horses talk? Cooool!" Nico exclaimed, still jumping up and down like a rabbit on chocolate bars.

Bianca blinked down at her brother.

"You… You went down to the snack bar and ate a bunch of candy again, didn't you?" Bianca realized.

Nico's eyes widened momentarily before he grinned up at her.

"What? No! Of course no-"

Only Percy's fast reflexes kept the kid from hitting the ground. Bianca sighed. Percy stared at the girl in shock, silently wondering how the girl wasn't freaking out at her little brother randomly passing out on her.

"He'll be out for an hour, then he'll be up and playing again," Bianca explained.

Ah. This had happened before. A lot, from the sound of it.

Wait.

"How long have you guys been here?" Percy asked.

Bianca blinked. A thoughtful look came across her face before the teenager answered. "Since… Only recently, actually. We've been here like a month." Bianca replied.

Percy, however, was now focused on her dress Bianca was wearing looked like it belonged in those old black and white movies his mother loved. At this point, Percy's Demigod instincts were kicking in, and they were screaming at him the same thing over and over again, 'danger, danger, danger'!

"... Bianca, what year is it?"

Bianca gave him an odd look.

"It's 1938, Percy. What other year would it be?" Bianca laughed. Said laugh died at the horrified look on Percy's face. "Percy? What's wrong, Percy?" the girl asked.

Percy really didn't want to say it. But, he couldn't not say it.

"Bianca… It's 2006. You haven't been in this hotel for a month. You've been here for over half a century."

The girl froze.

Half a century.

Half a century…

Which meant…

Holy shit, their whole 'entire week left' time limit might already be up. Why was Percy worried again? What had been the whole rush? Sally… Sally Jackson. Sally, his mom. Hades. World War III. Crap, even trying to remember was giving him a headache. This place was cursed. This place was cursed, and Grover and Annabeth...

"Here!" Percy thrusted Nico towards the shellshocked Bianca as he stood.

Snapping out of her daze, the girl glared up at Percy.

"Where are you going? You still haven't explained-" she began.

"No time! I need to get my friends! Then, we all need to get out of this place!"

"Carry Nico then!" Bianca snapped.

Oh. Right. Nico was probably heavy. Then again, there was a reason Percy was mentally calling Bianca Supergirl. On the other hand, the reason was because the girl had a mean hit, so best not to piss her off. However, Percy was also worried for his friends, so he couldn't be bothered with niceties, so… Nico di Angelo was tossed over Percy's shoulder like a sack of potatoes.

The little boy promptly curled up against Percy and began to snore.

"Let's go!" Percy exclaimed, before turning and running off, Bianca fast on his heels.

Annabeth, of course, was building a city. She already had several skyscrapers, a road system build in, a couple of parks… Was that a statue of Athena?

"Annabeth!" Percy called out.

The girl ignored him, content with her game.

"Wisegirl!" still, no response.

Percy gave Bianca a look. With the still sleeping Nico on his back, Percy couldn't exactly do much more than yell incoherently. Bianca sighed once more and held out her arms. Percy blinked before attempting to put Nico in her arms. Attempt being the key word as the kid decided to latch onto Percy the second he realized Percy was letting him go.

Then, Bianca began to mutter in Italian and Nico sleepily turned and let himself fall into his sister's arms. Bianca gave a small grunt but stood her ground. Huh. So that's how she had such strong arms.

Percy turned towards Annabeth, grabbed her by the shoulders, and spun her towards him.

"Percy, what-"

"This place is a trap. There are people from all different eras. Bianca is from the 1930's!" Percy pointed wildly.

"What? So? This place is awesome, just look at all-" Annabeth was having none of it and pushed Percy aside to get back to her city.

"Annabeth!" Percy cried out, "Hades, Underworld, quest, stopping World War III!"

"Stopping World War what? What is a 'World War'?"

Percy winced. Right. He'd dragged Bianca and Nico into this. Probably not one of his wiser moments.

"Who cares? Let the gods fight. They always fight amongst themselves, now-" Annabeth pushed Percy back.

It was time to pull out the big guns.

"Spiders! Big hairy spiders, covered in warts… Acromantula, like the ones in Harry Potter, crawling everywhere."

Annabeth froze, paled, then shuddered. Then, her vision finally cleared and wide grey eyes met Percy's.

"Oh my gods," she said, "How long-"

"Doesn't matter. We have to get Grover."

"What is a World War?"

Annabeth scrunched her eyes and turned towards Bianca.

"Who are you?"

"We're Demigods who are going to stop the next great war and save the world!"

Percy froze.

Annabeth froze.

Bianca froze.

…

"You were awake the whole time?"

A nervous chuckle was heard.

Bianca twitched and Nico yelped as he was dropped to the floor. Then, the boy stood, smiling. "We time traveled! Isn't that awesome, sis?"

Bianca glared.

"No, it's not awesome!"

"Why not? The world probably moved forward. Who knows, they might even treat people like- erm. Yeah," Nico paused, glancing at Percy and Annabeth with suspicion while scratching the back of his head. Percy and Annabeth exchanged a look. What was that about?

Bianca's eyes softened.

"Yeah, probably," the girl smiled at her little brother, messing with his hair. Nico's responding grin could light up a room.

"Grover," Annabeth spoke.

"Right, Grover!" Percy repeated, spinning and making his way towards his goat friend. Probably still shooting rednecks.

And, of course he was.

"Die, human! Die, silly polluting nasty person!"

"I like him," Nico commented.

"Grover!" Percy and Annabeth shouted. The Satyr paid them no mind, happily blasting away. Then, he spotted Bianca, swerved the plastic gun, and opened fire repeatedly. Percy winced.

And so it was that Grover was rescued from the Lotus Casino… With a lump on his head.

The group made their way out of the Lotus Casino and Percy shot towards the nearest Newspaper stand. He wasn't sure whether to laugh or cry at the date. June 20th, just one day shy of their deadline.

"Well?" he could practically feel Annabeth's breath on his shoulder, Bianca and Nico not far behind. Grover was still in a daze. Hopefully, it would fade soon.

"It's been six days. The Solstice is tomorrow. We have a day to get to Los Angeles, or Hades will start World War III."

…

"What the bloody hell is a world war!?"

"When did we get two new Demigods? Wait, why do we have two more Demigods! There's a reason quests usually have no more than three, you know.'

And, Grover had snapped out of his daze.

Percy laughed nervously.

"Erm… Guilty?"

"What are we waiting for! Let's go save the world!"

Let it said that children can look at such a devastating issue such as stopping a war capable of bringing the planet to it's knees with a smile on their faces and adventure in their minds.

Percy smiled.

"Let's!"

He received two smacks for his troubles, one from Bianca and one from Annabeth.

"Ow!"

"Explain! NOW!"

They both said that in unison. Dear gods, what had Percy gotten himself into?
