The Demon's Lullaby

It's been a while since we left Camp Half-blood. We're now aboard in the Argo III, the remake of the majestic Argo II which carried the Heroes of Olympus.
"Hey guys," Jason said, his Imperial gold glasses shining in the middle of the night. "Please have some Z's."
"Uhm. How about you?" Piper asked. "You've been driving the ship for 2 days already!"
"I'm okay." Jason said.
"Well, for me, I'll obey Jason. I want to sleep." I said and walked towards my cabin and drifted to Dream Land.
***
I think I've only slept for seconds when I heard a girl's voice.
"Chris! Chris!"
I opened my eyes and saw Annabeth, her shirt torn.
"What happened?" I got up and wiped my eyes.
"The ship! Upstairs! Fast!" she said and ran outside my cabin. I followed her and realized that there were.... Uhm.... Three snake-ladies? Uh, no. Four. I saw Jason in the corner of my eye, his body slumped in the floor guarded by a snake-lady.
"Hey you!" I called to a snake-lady. "Long time no see!" I threw a plate at her face.
"Ah. Christian Edwards," she said and walked towards me. "We've been looking for you for uhm... Weeks?"
"And so are you the most wanted demigod?" DJ asked.
"I don't think so." I did what my instincts told me. I punched the nearest snake-lady in the face. But my hands got wounded and at my surprise, the wound got healed in two seconds. I waved my hand and the sunlight managed to get in the ship and burn the snake-ladies.
"Well," Piper said, Jason in her arms. "I think you discovered your powers, Edwards." She pulled a bottle of ambrosia and managed to feed it to Jason then everything turned black.
