This story takes place after The Staff of Serapis. It's a crossover between Heroes of Olympus and The Kane chronicles. The main characters will be Percy, Annabeth, Carter, Sadie and others who will be revealed in later chapters. It will take place in camp half blood and the nome and maybe camp Jupiter. This is my first fanfic so reviews would be highly appreciated.

Disclaimer-I don't own any of these characters (but I would luv to).they belong to Rick riordan.

CHAPTER I

ANNABETH

Annabeth was sitting with Percy at the Poseidon table. She wasn't allowed to but after Tartarus, giants and Gaea being scolded by Mr. D didn't bother her. She had her armor on and so did Percy because they had capture-the-flag after dinner. Seven months had passed since their final battle with Gaea. All the buildings had been repaired and everything had returned to normal…or as normal as it could get in a demigod's life.

"CAMPERS! It's time for capture the flag. Get ready!" called Chiron over the chattering .A cheer went up around the dining pavilion. The Athena cabin was leading the Poseidon, Apollo, Hecate and Hermes cabin and The Zeus cabin (A.K.A Jason) was leading Aphrodite, Hades and all the other cabins. The campers gathered around their flags. Grey with an owl for the Athena cabin and gold with an eagle for the Zeus cabin. "So what's the plan, wise girl?" asked Percy with that troublemaker smile that Annabeth had come to love."

"The Apollo cabin will be defending and the Hecate kids will whip up some illusions to distract the bulk of the enemy and then we can skirt around the perimeter with the rest of the Athena cabin and get the flag. Easy", she replied.

"Or…we could just fight stuff."

"You're such a seaweed brain."

"And you know you love me for it."

They took up their positions in the woods. Chiron blew the conch horn and they charged west. She saw a shadowy version of her, Percy and the Athena cabin running east, surely an illusion made by the Hecate cabin. They made it to the river and could see the enemy banner on Zeus's fist. There were only two guards. They heard a shuffling sound behind them and turned to see Jason with his sword drawn standing behind them.

"How did you know it wasn't us?" Annabeth asked. "I've seen enough of Hazel's tricks to know the difference." Jason said with a smug smile.

"At least I can now show everyone that I'm a better swordsman than you" , Percy said uncapping Riptide. "Save it, Jackson." Jason said. "You do know that you're outnumbered, right?" she observed. "Am i?" he replied glancing behind them. They turned to see Nico step out of the shadows.

Before they could continue their banter, they heard screams coming from the eastern part of the woods. They all glanced at each other and then ran towards the direction of the screams.

At first Annabeth thought: Hydra

But the monster before her had only one serpentine neck instead of twelve, and head and the rest of its body was of a leopard. Its body was as big a small car. Its neck was so thick it could have swallowed her whole, the only reason it hadn't, Annabeth thought, could be that it was surprised at the number of demigods in the woods at that time. But she knew that shock wouldn't last long.

Annabeth went left, Percy went right and Jason attacked its head. It snapped at Percy but he dodged and stabbed it in its abdomen. Jason decapitated it and it burst into golden dust…no, sand.

"What was that?!" Jason asked shocked.

Percy shrugged, "nothing I've ever seen."

Annabeth turned to Chiron, who was standing there dumbfounded. His eyes were distant. The color had drained out of his face. He gave Annabeth a look like, later. "Everyone return to your cabins. Now." everyone shuffled back to their cabins while constantly murmuring.

They waded their way through the woods. They wished Jason goodbye and then Percy walked her to the Athena cabin. "You got any idea what that was?" Percy asked. "I've got a suspicion, I'll tell you tomorrow."

"Okay, see you tomorrow "

He kissed her goodnight and left. Annabeth walked to her bunk and opened her bedside table. She took out the phone she kept for emergencies and searched for a particular contact. She found what she was looking for and stared at the name above the number. Sadie Kane.
