This is my first fic so it's probably not very good. Please review. I don't own anything that you recognize so with that being said, read on.

Percy and Annabeth have been going steady for 3 years, everything seems perfect until they meet 12 children. Some of them their children. By going back in time they hope to stop the horrible disaster of everyone at their camp being brutally murdered. Friendships will be tested, fighting will happen, and family arguments will occur, they will be put to the test, and it may be to hard for them to win. Well guess what, it's time.

Chapter 1: It's time to wake up.

Percy pov

I was having a rare dreamless sleep when I was very rudely awakened. "Wake up you idiot!" someone screamed in my ear.

I sat up fast and smacked my head on something. "Shit," I swore angrily. I looked at my clock, 2:14 a.m.

"You idiot!" the voice yelled again.

I looked up at my smoking hot girlfriend, she looked both angry and troubled. I saw her rub her forehead and grimaced. "I'm sorry, baby," I apologized sweetly.

She softened up and and sat at the end of my bed, crossing her legs. She bit her lip and fingered her necklace, I sat in front of her and put a hand on her knee. "Percy," she sighed.

"What's the matter? Are you alright?" I asked concerned.

"I had a nightmare. We were surronded, there was only about 10 of us against approxiamately a hundred monsters and enemy half-bloods altogether. Then a guy, he was about 25ish stepped forward, he had gold eyes. You fought him then he pulled a cheap move and shoved his sword through your weak spot. He laughed. You fell to the ground...and never got up." she whispered.

She started crying hysterically and buried her head in my chest. "Kronos kills me?"

"You don't seem to worried," she stated dryly.

"What happens after that?" I dodged.

She gave a frustrated sigh and said, "I don't know, I woke up screaming."

Silence followed and I finally spoke up after a few minutes, "It's going to be alright, you need to go back to sleep." She noded and layed down, I layed down next to her and wrapped my arms around her waist. She smiled briefly and we both fell back asleep.

3rd person pov

A dozen kids stared at the burned down remains of their camp and for some, home. It was a smaller version of the one located in New York except this one was in the United Kingdom. Before the war began, there was about 150 half-bloods and mixed-bloods staying there, only 12 remain. They were lucky, if they hadn't snuck out to see a concert, they'd be dead along with the others. Only 3 of the kids parents weren't dead because they are gods but if they don't act now, they will die too. All the kids were either crying for their lost friends and loved ones or standing there, shocked.

They are all very alike, yet total opposites, the oldest being 19 and the youngest 13. There was an even amount of boys and girls, they were all friends, family, or both. They were a strange sight, they all were wearing black rock clothes from the concert they were at just an hour before and all their faces were distorted in pain. The girls' black make-up was running down their faces while they thought how cruel this world was.

Suddenly, a black haired, green eyed boy stepped forward and turned to face them, he was the oldest of them all, also an exact replica of his father. He cleared his throat loudly and all his companions turned to face him with watery eyes.

"This isn't over, we'll fight back! This is what we were trained for, before you argue with me, I have a secret to tell you," he said. A girl stepped forward with curly gold hair and gray eyes, she took his hand and he squeezed it reassuringly.

"We've been working on something," she began. "A time portal. We got the idea from Kronos himself, it's in the shape of a shield. We've already tested it on a cat, it works. We can avoid this disaster if we go back in time, we can still win!"

A couple of the children smiled and murmmered approvingly among themselves, the rest just stared at them dumbly. The blonde girl looked at the boy with a sudden sense of alarm, he smiled at her. "You still wearing the ring I gave you?" he asked.

She held up her hand and a green pearl was on a silver band, she gave him a confused look them her eyes widened in realization. "No way! You put it in the ring, didn't you?" she said admiringly.

"You're the only one I can trust." he smiled.

She smiled appreciatviely and gave him a quick kiss. "You are a genius, now how does this work?"

"Twist it twice counter-clockwise and once clockwise to go back in time. To go into the future, you have to do the exact opposite: twice clockwise, once counter-clockwise."

"How do you know how far back it's going to take us?" a 15 year old boy with hair as dark as night, pale skin, and black sunglasses on despite the fact that it was night, asked.

"It's very advanced, it takes you to the time you need to go by reading your fingerprints. It's hard to explain," she said. "So if everyone has their weapons we can go now."

She looked around, everyone had their weapons so she exchanged a glance with the green eyed boy then twisted the pearl. It turned into a giant shield, it was wider than her and as tall as her shoulders, despite it's size, it was extremely light.

Each child stepped into it one at a time until only her and the green eyed boy were left. He was about to step in it too when she grabbed his hand quite suddenly. She propped the shield up against a tree and put her arms around his neck, she kissed him long and serious. He twisted his hands in her hair and they tripped and fell into the portal.
