Chapter 1: Arrival

Percys POV:

AHH, HELP!
Man I can't get 1 day of peace, I was sitting on the beach with the other members of the seven, Nico, and Thalia when I heard the yell for help. Everyone jumped to their feet and sprinted towards Half-Blood Hill (where the yell came from). "What was THAT?" Said Annabeth panting.

"I don't know, but it didn't sound good." I replied, I meant it the cry sounded like the caller was in severe pain.

"NOOO." Came the same voice sounding like they were being choked, it seemed like a girl was the one yelling. "WE… CAN'T… LEAVE…HIM." The voice was cut off by something, but I was defiantly a girl. Then we made it to the hill and saw something shocking two campers, one boy, and one girl each helping each other across the line both were leaning on each other and looked about 14. Suddenly Annabeth and Thalia stopped dead in their tracks both looking at Thalia's tree.

"Annabeth what are you-" then I saw, it a boy was up in Thalia's tree waving a sword trying to distract something I couldn't see. Just like what happened to Thalia, Luke and Annabeth when they came to camp. "Ok, Thalia, Annabeth, Nico, and Piper help those two into camp and two the infirmary, the rest of us will help the other one. Me and Jason Started up the tree toward the boy, and saw 3 chimeras flying right at us. "Frank try to shot them." He did as he was told and started fired an arrow hitting 1 of them chimera in the eye and turning it to dust. Frank was shooting another when the boy above me and Jason jumped out of the tree with his sword above his head. The boy was hit right in the calf by Frank's second arrow blood seeping down his now injured leg, still in the air the boy stabbed the second chimera in the head turning it to dust and falling to the ground with a bone shattering snap. It all happened so fast. I quickly through my sword and sent it spiraling at the chimera killing it on contact.

"Woo!" Yelped Jason sliding down the tree, once we were on the ground piper was running back up the hill. She the boy groaning boy clenching his right leg, and left knee, and crouched next to him starting to charm speak.

"You're ok, you'll be fine." She said

"I'm ok, I'll be fine." Repeated the boy going limp.

"What did u guys do throw him out the tree?!"

"Throw out of the tree…" the boy said still deep in a trance. I did my best to hold back laughs, but failed miserably.

"He- he jumped." Said Jason while Piper glared at me for laughing

"Well let's get him to the infirmary." She said sighing

"Infirmary…" mumbled the boy as we picked him up

"Yeah yeah we're going there." Said Frank picking up the boys sword.
