Thank you to BibiaValeS2 and Ralph H for reviewing.

Percy floated in the ocean, not knowing where he was or why he was there. He looked around before seeing that he wasn't alone. He swam over to a figure that was sitting comfortably on the ocean floor. She had black hair like his, her eyes a darker sea-green than his. She wore a blue shirt with a green skirt. She didn't seem bothered by the underwater currents that ruffled her long hair as it flowed past. He stared at her as she calmly grabbed a seashell and admired the colorful patterns. Her hair swirled behind her in a mesmerizing way, it took Percy a while to stop staring at it.

He regained his concentration and he walked over to her. "Hey, you." The girl turned her head and let go of the shell. It floated in place for a moment before dropping back to the ground. The girl jumped to her feet and was about to swim away when Percy said. "Wait." She stopped and turned to him. Her eyes glowed a dim light of sea-green as she stared at him. "How long have you been sitting there?" He knew it sounded like a dumb question, but he wanted to know if his suspicions were correct.

She took a moment of hesitation before answering. "About a half hour, why?"

He felt a sharp pang in his gut as he slowly understood who this girl was. "Poseidon." He blurted.

She stared at him. "What about him?"

"He's your dad." He said it hesitantly and waited for the answer he dreaded. After a small pause she nodded. He felt like an anchor had been dropped on his chest.

"Is he yours?" He nodded and she mouthed "Oh". They stared at each other for a long moment before a loud cry startled them both. "Must be another sea horse in trouble." She said before looking at him as he nodded. They both went off to find the sound.

After swimming a few yards they could see a sunken ship in the depths of the water. As they got closer they could see a group of sea creatures swimming around something stuck in under the ship. Children of the sea god! One of the creatures said in Percy's mind. Please help.

One of the hippocampus got stuck under this wreckage. Another of the sea fish wailed.

Please help him.Said another, sounding depressed as he pleaded with them.

"Don't worry," The girl said. Percy wondered if she had also heard the fish conversation. "We'll help your friend." She turned to me. "I'll ask your name later, unless you want to offer it." She said before going over to the ship's wreckage and pulling on one part of it.

He swam over to her and also started pulling it up. "Name's Percy. Percy Jackson." He grunted as he struggled to pull it with the fish chanting in the back of his head.

She pulled harder against the wreckage. "Amy," She said, grunting. "Amy Holder." He acknowledged her before pushing against it to push it higher. After a while she sighed. "Stand back, or I guess swim back. You get what I mean." He did as she asked as she closed her eyes in concentration. She put her hands out and pushed them up. At first nothing happened, but then the entire ship began to float upward towards the surface. The hippocampus swam against it until it was freed, and it followed its rejoicing friends as they swam away.

Thank you, children of the sea god. One said before it swam away with its companions. Amy kept her hands up shakily for a few seconds, then she let go of the ship, falling to the ground in exhaustion. Percy swam to her as the ship fell back down, making some sand fly up before settling.

"Are you alright?" He asked her, hand outstretched. She seemed dazed for a few seconds before she took his hand, and he pulled her up steadily.

"Fine." She said, strained. She looked up at him. "Thanks for helping." She mumbled.

"You did most of it." He said before he laughed, and she did a strained laugh after him. An awkward silence settled between them. "So," Percy started, breaking the silence. "See you some other time?"

She nodded and held out her hand. He shook it. "Nice meeting you Percy."

"Where will you go? I know of a camp in where you can be safe."

She laughed steadily this time. "I-"

A rumble stopped her as creatures struck her down. They came from the ship, encircling her and keeping her down. She struggled against them, but to no avail. Percy felt a pain in his gut as she was struck by a telekhine in the face. She winced in pain and he did the same. "Amy!"He shouted, but he felt farther away. He tried to help her, but he couldn't reach her. She was struck again, and again he felt pain inside of him as she yelled out in anger. Again she was struck, and this time it was Percy that yelled out in anger. He tried again to swim to her again but gave up. He yelled agin as she was struck a fourth time and the scene dissolved.

Percy woke up, his body covered in sweat, as if he had actually been out in the ocean. He looked outside and saw it was still nighttime. He slowly calmed his breathing and let his head drop against the back of the wall. He wondered if that had all been a dream or if it had been real.

He couldn't keep his eyes open long enough and fell back into a deep sleep.

He woke up to the sound of car tires. He was in one of the cabins close enough to hear anything from the camp's borders. He got up and looked out to sea. Light was barely showing above the water, saying the day is early.

He got up and walked out of the cabin, walking towards the edge of camp. He heard voices coming from around there, so he wanted to know who they were and why they were here so early.

When he turned a corner he froze.

She stood right in front of him, frozen and staring at him as well.

...

Hours before arrival...

Hazel

Hazel stood before the girl, who slept on one of the infirmary beds. She felt angry at the gods, for breaking their vows and having children that had to pay a high price as heroes because of the gods' mistakes. Frank had left her alone after speaking to Reyna, so she was thankful to be alone for a while. She felt confused and a little bit shocked that she was who she was.

She looked over at the girl, who looked like she was in a vivid dream. Her eyes moved from side to side under her eyelids. Her fingers twitched as if she were grabbing or doing something. After a while she started shaking, but Hazel just stood there, watching. She couldn't believe that the girl was having a vivid dream. Her brow furrowed and she drew a quick breath. She tensed and started thrashing, and that broke Hazel out of her daze. She jumped on the girl, trying to pin her down before she made a ruckus and woke everyone. She started to scream, but Hazel put her hand over the girl's mouth, muting the scream as she kept thrashing. "Stupid dreams..." Hazel cursed under her breath. This girl was worse than anything she had ever seen, and that's saying something.

The girl's eyes opened, and she easily pushed Hazel off of her. Hazel scrambled before standing, and the girl stared at her, first looking at her before looking at the double doors behind Hazel. "Wait-" She was pushed by the girl as she ran for the doors, stepping over hazel as if she wasn't there.

As soon as she had risen she ran to the double-doors and looked out, seeing the trail of water and destruction that followed the girl. She looked at some confused guards and shouted, "After her!" They ran after the girl as Hazel ran in front of them, trying to reach her before she did anything she would regret.

When she reached the border of New Rome, she saw the girl struggling against Terminus, who kept her confused and shouted at her. She saw the guards and Hazel right before she bolted through the boundary line. When Hazel reached Terminus he looked at her with disappointment. "You saw the girl! She's destroying the great things of Rome! You need to stop her!"

"That's what we're trying to!" She yelled after him as she followed the girl's trail of water. She remembered there were rumors of a pond that led to the river that started or ended behind New Rome. She never payed attention to them, until now. She went a detour route, away from the girl, and followed a row of houses before seeing the pond. She arrived there first. The girl came crashing through, pushing against Hazel to get to the river. Hazel was ready for the shove.

As she fell she pulled the girl down with her. The girl struggled against her, but the girl was able to reach out to touch the river water, giving her more strength than Hazel could ever gain. Before the girl could shove her away for good Hazel yelled, "Amy!"

The girl froze and stopped struggling. "How do you know my name?" She demanded, but she sounded afraid. She had gone through worse things imaginable than Hazel could imagine. The guards rushed over to the both of them and pulled Amy away from the water, making her lose her connection and her strength. Hazel felt someone pull her and she looked up and saw Frank pulling her to her feet.

She took a deep breath before asking Frank. "Do you have the letter with you?" He shook his head as he brought it out of his pocket and handed it to her. She walked over to the shocked girl and handed it to her. "You came here in a crate filled with sea water, and it came with this. The girl began to read it:

Greetings,

to whom it may concern,

Encased in this container is Amy Holder, age 14, almost 16, which does not know much about the Greeks and Romans. She knows her father is Poseidon, god of the sea, and she enjoys staying underwater for hours at a time. She does not know who I am, but I do. I have watched over her for many years, and hope she will be in good hands with you fellow Greeks and friendly Romans. Will she ever be united with any family members she does not know, she might become overwhelmed and attack savagely upon whom it is. She was born from Poseidon when he was angry, dangerously sending storms around the oceans. He was entirely enraged that he somehow had her out of the ocean in which her mother loved in chaos as well as he did at that moment. She has a sibling, a 12 year old boy named Maximus, Max for short, and is very protective over him. Please make sure to find him and keep them both safe from any harm. Whomever you are, please take precious care to protect them, for old enemies and creatures are stirring, worse than the giants and titans. It is as old as Gaea herself, born from Darkness.

May this message be heeded, and it will not be of any concern to others as it is to me, but they will grow old with the years instead of searching for great places to be in.

Farewell, and heed my message to you.

...

She ran to him before anyone could stop her. He embraced her as if they were loving siblings that had known each other for years on end. "Percy," She whispered in his ear as he rubbed her back. She felt tears in her eyes, but she couldn't stop herself.

"Shh," He said encouragingly. "I was worried about you." He said after a while. "I saw them take you, and I wanted to help. I thought it was a dream."

She laughed softly. "It was." He looked at her questioningly, but she explained. "You weren't really there, but we did meet." They stayed together in their first embrace, holding each other as if it would be the only one they ever have.

"Percy?" A voice said from behind them. He turned to look and he saw Hazel staring back at him with questioning eyes. "You know her?" He nodded and she asked, "Since when?"

"Last night." She didn't seem to understand but she didn't ask questions. He backed out of the embrace enough to see the tears in her eyes. "Did you miss me? You hardly know me."

She laughed again. "You're my brother, how wouldn't I?" It stayed that way for a few minutes before a shout.

The moment was broken when Annabeth came running.

Annabeth

Annabeth sat bolt upright, the same images and words from her nightmares haunting her wake. Ever since she visited Percy's apartment, she couldn't get away from them.

She thought about how Percy had kissed her when she had looked at him. She had been laying on his bed (irony) and he had held her with care but anguish as well. It seemed...-

A loud thump startled her out of her thoughts. She listened intently, slowly and quietly uncovering herself and changing into day clothes. She heard no noise as she grabbed her Yankees cap off of the nail near her bed. It had started working after her and Percy's adventures with the Kane siblings.

Another thud sounded from the ceiling. She felt the magic from the invisibility cap. Silently, she walked to the door.

The air was cool against her cheeks, her hair flowing lightly to the side in its ponytail. She went to the side of the armory, which was connected to the Athena cabin because of them knowing the right weapons for each campers.

Only few of the Athena children knew of this area, each sworn to secrecy. She placed her hand beside the owl of Athena, and, as expected, a pair of slits opened up in the wall and slid metal rungs, forming a ladder. Slowly she began to climb up, making sure to make no noise as she listened intently for any other sound.

The Athena campers always wanted a place to study the stars and to have a quiet place to spend a few hours, so they had a few Hespheastus campers, sworn to secrecy, build them an observatory, which they used as an observatory and As a place to study maps of ancient scrolls from around the world. They also had textbooks on the stories of the gods and on different subjects.

As she slid to the last ring and stood, another footsteps was followed with a lot of rummaging, then page-turning followed. She stood up and turned around the corner of the study and was faced with the source of the noise.

Before her stood a boy or about age 14, tall but slim wired, had grey eyes that seemed to be clouded with thoughts, and had tanned skin. He stared intently at a book in front of him with the spine reading Myths of Athena. His right hand slid from his side to the end of the page, slowly turning the page before coming back to his side.

He stayed that way for a few minutes before his eyes focused and he glanced in my direction. "I know you're there, Mom told me. " He said before turning the page again and reading again. She turned and, looking away from him, she -

"Don't take out your dagger, I can't hurt you." He closed the book as she looked at him, letting go of the hilt of her dagger. After a while he tilted his head, As if he were listening to someone who was talking to him. Then, "Please take off your invisibility cap so that I can look at you as I speak to you." Another tilt, " Annabeth. " He added her name as an afterthought, but it came to her as a blow to the gut. Slowly, and carefully, she took off her Yankees cap, and she knew by his look of surprise that he hadn't expected her to appear so close to him.

"How do you know my name?" She said it questionably, but also hesitant. He saw her hesitation and sighed.

"I told you, Athena, or Mom, has been telling me all about you, and-" another pause, then- "Perseus, or Percy. You two have done a lot more than Mom wanted to happen between you two, but I'm okay with it. It seems cool to have a sister that has a cool boyfriend."

Annabeth was speechless. He knew everything about her, and was her new younger sibling. Why hadn't Athena warned her about a new child? "Who are you?"

"Oh! I actually forgot! Sorry, I just got a little carried away. " He held out his hand. "Alexander Cartwright, but you can call me Alex." He dropped his hand when he saw that she wasn't going to shake it. He rubbed his hands together. "So! Where do we go first? Athena only told me to find you so that you could take me to a Big House?

She facepalmed. "Right! Chiron has to see you to allow you into camp! Come on, but you aren't allowed up here without any one of me or specifically chosen Athena children, so don't go asking around. Only few even know about it." He nodded and followed her down the ladder and walked behind her as she took him to the Big House. She had a lot of questions for her mother the next time they met.

Before they could reach the Big House,she heard a commotion coming from the camp entrance. She changed course and Alex followed without question. As soon as she got there,all of her blood went to her feet.

Percy and some girl were embracing, Hazel, Reyna, Frank,and Chiron watching around a white limousine.

The next second she didn't see them, but in the girl's place was a hooded figure. When she looked more closely, Annabeth saw a mask on the face. There was something beside it, a lump on the ground where Percy had been standing. As Annabeth's eyes adjusted, she was it was a human, but it wasn't breathing. Before she could even run to it the hooded figure looked at her and nodded, pulling the body up to show a face.

Percy, thought Annabeth before the scene changed back to what she had seen before the vision. The girl was still holding him, and she had something in her hand...

Before she could think about it she ran towards them and put on her Yankees cap when Alex shouted, "Annabeth!" Percy and the girl jumped apart and turn to look at him, since they had no clue who or where he was from. Annabeth ran and jumped, arms outstretched, into the girl, who stumbled.

As the girl fell, Annabeth pinned her arms and legs as best she could. The girl struggled against her, trying to gain the upper hand while Percy just stood there, shocked by the scene before him. All he could see was the girl struggling against nothing. As Annabeth pinned the girl's arms down, she was hit by an object on her side. Before she could steady herself the girl pushed her off and tried to pin Annabeth down but missed since she could not see her. As she looked at herself, Annabeth saw that she was drenched in water from the lake. So that's what hit me, she thought before dodging another one of the girl's grabs.

She dodged one more punch and threw herself back onto the girl. The girl gasped, "Percy!" The word was like a punch to the heart. Who did this girl think she was? Annabeth thought as she pinned the girl once more. And why did Percy hit me with water? The girl stopped struggling suddenly and another blast of lake water hit Annabeth square in the chest. She went flying as the girl scrambled to her feet. Annabeth felt her back hit a tree as she crumpled to the floor, her Yankees cap falling off her drenched head.

She knew from everyone's faces that they were all looking at her. Percy was helping the girl up, who was not drenched in water(how odd), and making sure she was okay. Alex was walking backwards to hide behind the nearest cabin so that he wouldn't be seen. Hazel and Frank were standing still with their mouths half open, wondering what had happened. Reyna was speaking to Chiron in a low voice about something.

Now Percy stared at Annabeth, the girl at his side. He walked over to her and as he raised his hand, Annabeth flinched involuntarily, hoping he hadn't seen her flinch.

Percy did. He lowered his hand and wrapped it around the girl, hurting Annabeth more than before. "Annabeth," he whispered, his voice giving no emotion. The neutral sound of his voice cut through Annabeth worse than what he said next.

He looked straight at her and said:

"Why?"
