The Big Three (A Percy Jackson and 39 Clues Crossover)

Prologue

Attleboro

     "HAAIYAH!" Dan Cahill sounded followed by the breaking of china.

     "Dan! God, that's the second vase you've broken this week!" Amy, his sister, shouted from her bed.

     "Sorry, Amy. Gotta practice my ninja skills somewhere, right?" Dan grinned.

     "No, you don't. And go get ready, we have to go to the square," Amy said.

     "Why?" Dan asked.

     "Don't you remember, dweeb?" Amy asked looking up at the ceiling.

     "Nah, I don't remember boring things," Dan replied, attempting to break another vase.

     "We've gotta pick get some supplies for Nellie's gateau la chocolat. Whatever that means," Amy replied.

     "Hey, it's got chocolate in the title, how bad could it be? But why can't you go? Why me too?" Dan asked.

     "I don't know. Fiske told us to not leave the house alone," Amy replied, shrugging to the ceiling.

     "All right, I'll go," Dan replied and marched out of the room.

     Dan went to his room, gave a couple of clothes the sniff-test, as he liked to call it, and put on the best smelling one.

     He met Amy back in the drawing room.

     "Ready?" Amy asked, sitting on the sofa.

     "Yup, come on," Dan replied.

     They made their way outside. Their brand new Audi was waiting outside. Dan only knew the stuggle. He had to beg 2 weeks to get Amy to buy it. Their driver was waiting and they got inside. Amy told him to take them to the public square and they were off. Finally, after 10 minutes, they reached the square and got out. Dan could smell chocolate.

     "Hey, Amy. Quick suggestion. You go and buy the stupid ingredients and I'll go and investigate that sweet smell of chocolate," Dan said.

     "No way. Fiske said not to split up and we will not split up," Amy replied firmly.

     They went into a shop and bought all the ingredients. Flour, milk, eggs, milk chocolate, dark chocolate, oil and for some weird reason-cheese. When they got out, Amy saw someone.

     She noticed a boy, no older than 13 or 14 having a sword fight with a man in a suit. At first she thought it was a stunt or something, but they were aiming to kill. That's when she noticed the man really. His eyes were glowing scarlet and there was anger and hate etched in every line in his face. The boy was definitely losing. How come the other people in the square weren't noticing them? Then Dan appeared next to her.

     "Those dudes have such sweet skills!" Dan exclaimed.

     "You see them too, right? Swordfighting?" Amy asked.

     "'Course, but it's just a stunt, right?" Dan asked, chewing on his cheese-burger.

     "Dan, look at their movements! They're actually aiming to hurt the other and see the expression on the man's face. Why can't anyone else see it?" Amy asked.

     "They think it's just a stunt, like I did," Dan replied.

     "I don't think so. Look," Amy said. She stopped a woman passing in front of her.

     "Excuse me, mam, but do you see those two. The man in the suit and the boy?" Amy asked.

     The woman squinted where Amy was pointing and nodded. "Yes, dear I see them just fine."

     "And what are they doing?" Amy asked.

     "Well, it certainly seems like they're talking. The man probably knows the boy," The woman replied and then looked anxious. "Why, dear?"

     "No reason. Thank you." And Amy steered Dan away from the woman. "You see? Those people aren't seeing them sword-fighting, they-" But her voice was cut when the boy fell down on all fours. The man raised his sword. "NO!" Amy shouted without thinking. The boy didn't notice but the man did, he locked his eyes with Amy. The boy saw his chance and thrust the sword in his stomach. It should've killed him but the man just laughed turning his back to the boy. He clapped his hands once and suddenly the boy stood up and his arms locked at his sides and his legs stuck together. He looked as stiff as a board. Amy could see he was trying to struggle. The man started walking and the boy lifted a few inches off the ground floating and followed. To Amy's horror, she realized the man was walking right up to her. He and the boy stopped right in front of them. He looked like he was sniffing something, much like a dog.

     "You are mortals. But you can see us?" The man asked.

     "Y-y-yes," Amy replied, her stuttering getting the worst of her.

     "Aah, you are Cahills. And Cahills who can see through the Mist. How . . . refreshing. I've been searching far and wide for a Cahill who can see through the Mist but haven't found one. No matter, I did now. You smell really tasty, you know, both of you," The man said, his voice turning into a hiss. "But alas, I cannot touch you, not with the Gods' blessings."

     "What blessings?" The boy managed to ask.

     The man turned on him. "You are lucky, Percy Jackson. I only came here to find what I needed and I did. We'll see each other soon, I suppose." And with that, the man shimmered and vanished into thin air. The moment he dissappeared, the boy called Percy Jackson broke free and landed on his feet.

     "Did that dude just call us tasty?" Dan asked incredously. He pointed to the boy. "You owe us explainations."

     "Thank the Gods, I finally found you two," Percy muttered.

     "Wait, so the monster man and you are looking for both of us? Why?" Dan asked.

     "Not here. Can we go somewhere where nobody will overhear us?" The boy asked.

     Amy hesitated. "Sure, come on."
