Notes: I got this idea off of Pinterest (and I'm pretty sure it came from Tumblr), so the idea itself does not belong to me. I'm not quite sure who it does belong to, but I wrote this story. I did change a few things to make the story flow better. Enjoy!

Annabeth's POV

Annabeth was studying hard. She was in fact staying up close to midnight. Piper and Reyna had tried to get her to go to sleep. "All this studying won't do you any good without resting!" They echoed over and over again. Annabeth wanted to, she just couldn't. If she failed this exam there was no way she would get into that college with the excellent Architecture program.

"I'm so tired," she whispered to herself.

"Maybe going to sleep would help?" Nico di Angelo said from outside the door.

Annabeth jumped. She was staying with her friend, Hazel, while her father was off on vacation with her step brothers. Annabeth had chosen not to go for the benefit of good grades. The only downside to staying with a caring friend was the brother that popped out of no where.

Don't get her wrong, Annabeth adored Nico. He was wise and sweet. His boyfriend, Will, always gave her tips to stay healthy. But if he would just not pop out of no where sometimes, she would definitely have more positive feelings about him.

"Tried. I'm too stressed," Annabeth made an excuse.

Nico's eyes glazed over with thought. "Is it because tomorrow is your birthday?"

"Yeah. What does that have to do with anything," Annabeth panicked with confusion. What could possibly be so stressful about her birthday? It happened once every year.

It's your eighteenth birthday," Nico pointed out and emphasized with a half-hearted hand gesture.

Annabeth melted with dread. On everybody's eighteenth birthday they would take the body of their soulmate. That meant that her body would go through the same thing. Somebody was going to take over her body too. She would have no say. However, she would be in some strangers body, hopefully not screwing up their life. She was always so afraid that one day somebody would appear in her body randomly.

When she turned back to respond, Nico was gone. She assumed that she imagined it and that her birthday was not going to be tomorrow. She glanced at the clock. Too tired to read it, she dozed off and fell asleep.

The next morning she woke up. She was not in her room. In fact, it wasn't even her real room. Annabeth was the lying in the bed of a teenage boy. She bolted up. She panicked and lifted up the sheets. She wasn't even in her own underwear! She got up and saw herself in a mirrors- only she wasn't herself.

She was a boy with dark hair and sea green eyes. He was tall, it muscular. Annabeth spotted an expo marker by the mirror. She uncapped it and began to write things on the mirror. She was almost done when a woman came in.

"Percy, what are you writing?" She glanced at the mirror. Then her face lit up. She looked like a proud mother. The woman grabbed Annabeth's arm and dragged her to the living room.

"It's your birthday? Happy birthday sweetie! Your name is Annabeth? I'm making you a cake!" The woman fussed and ran about the room.

"Um, who am I?" Annabeth squeaked. Her voice was low, but graceful.

"You are my son. Your name is Percy Jackson," Mrs. Jackson explained as she rushed around the kitchen. "You should go to school."

Percy's POV

One second he was playing video games. The next he was sitting st the desk, jolting awake with a serious need to use the bathroom. He rushed through the house looking for a room with a toilet. Then suddenly a tiny person appeared next to him, scaring him so bad he almost peed right there.

"What are you looking for?" he asked.

"Bathroom," Percy muttered. The person lead him to the bathroom. As he was washing his hands he looked up and saw himself. When it clicked what was happening, he freaked out. This beautiful woman is my soulmate? When he left and returned to the bedroom he almost lost control of his bladder again. Not only was she beautiful, she was crazy smart. He decided to go to bed, he would need to sleep so he didn't mess up this girl's life.

"Annabeth! Ugh, you are so not a morning person!" a girl screamed. A tiny girl with golden curly hair walked in. Percy, however, was already awake. When the girl came in to a confused Annabeth going through her dresser looking for clothes.

"Oh shit!" The girl screamed. "It's her birthday!"

The girl ran out of the room and came back with a packet of papers. She sat down next to Percy, stuck out her hand, and shook it introducing herself as Hazel.

"So Annabeth, being the smart-ass she is, prepared for this. I've go the outfit you can wear here...And she also has a form to fill out so she can find you," Hazel began to hand Percy things. "She also wants you to try not to get her killed today! Anyway, Nico can help get you to stay home today. Annabeth wouldn't like it, but you don't seem to smart and, in my opinion, you should stay here with him."

Percy did his best to try and understand it, but Hazel seemed to be in a rush. She probably had school. A guy walked into the room wearing nothing but black shorts. Percy hoped he wasn't the brother. Or the guy he met last night.

"Hazel, Persephone is gonna bring you to school," he said.

"Why don't you have to go?" Percy asked.

"Doctor's note," the boy winked at him.

Hazel got up and gave a brief eye roll at the comment. "Nico, can you stay home with him? I'll tell Persephone to call the school that Annabeth is sick."

"Ugh, fine. But if I have to babysit him while he fills out those papers Anna-"

"Excuse you? Babysit me? I'm not a child!" Percy interrupted.

Without skipping a beat Nico merely continued. "Promise to not get stuck at school. This person isn't going to sit here and we know it."

Hazel rolled her eyes for the second time that day. Then she quickly left. Nico turned toward him and gestured to follow him. They walked outside to the backyard. There was a large fence around it that nobody would ever be able to jump. They sat down at a table and Nico watched him began to work.

"Percy Jackson?" Nico asked.

Percy nodded and continued to work. He wanted to get this done. He was gonna figure out how to get back home so that he could meet her.

"I'm gonna get my phone," Nico said.

He walked back into the house and shut the door. Percy finished a little while later. He went to go back inside, but the door was locked. He pulled and tugged. He started to yell. Nico came to the door.

"What?" Nico asked. It was hard to be intimidating talking to a ghost boy almost his height.

"Let me in! It's hot out and I'm bored!" Percy demanded.

"Sorry Jackson. I have a doctors appointment later and I don't want you bothering me. Just stay out there until Hazel comes home," Nico walked away.
