I couldn't sleep that night. It wasn't because Tyson was snoring his head off. It wasn't because of the storm rumbling in the distant. It was because this quest and Mars telling me to steal from my dad. I was going to talk to my mom tomorrow and see what she'd think about all of this. Instead, I got up and padded out to the back of the cabin and stared out at the lake. It was so calm and the moon shone nicely on the surface.

"What do I do, Dad? I seriously doubt you don't know about Mars and what he asked me to do. Now Thálassa, Grover and Annabeth are going. I don't want them to risk their lives to break into your kingdom for Mars. Please say something." I know, it was kinda desperate, but I really needed help. I couldn't wait until the morning or Mom'll think I'm ill when I haven't slept. I stood staring at the water, sending mental messages to my dad, hoping for some sort of sign.

"Talkin' to ya dad?" I looked round. Thálassa stood there and Annabeth was with her and she looked worried. I nodded. Tyson snorted and rolled out of his bed.

"Hello Annabeth." He saw Thálassa. "And new girl."

"Hiya Tyson." Annabeth smiled at him. Thálassa nodded her greeting to my brother. Annabeth moved to stand next to me, taking my hand. She asked what I was thinking. That's what I'd love to know. I had no idea what I was thinking. I just shrugged and looked back out at the water.

"I don't know, Annabeth. Nothing makes sense anymore." Annabeth sighed and squeezed my hand. "What are you all doing here anyway? If you get caught-"

"I don't give a damn about bein' caught. They can bring it on. Percy, ya're comin' with us tomorrow." Thálassa said firmly, as if promising and challenging me at the same time. Her green eyes lit up with determination and power. As far as I knew she was staying in the Hermes cabin until Chiron figured out who her parent was.

"But-" I started to protest but Thálassa cut across.

"Don't worry about ya mom. I got this all sorted out." Thálassa seemed so confident about this, I couldn't think of anything that could go wrong (ha ha- demigod luck will be running true to form, I can guarantee it). "Just get some sleep 'n' I'll drop by at sunrise." And she left.

"New girl very positive." Tyson said.

"You're so right, big guy. You can go back to sleep now." Tyson yawned, nodding. He rolled back into his bed and was asleep in seconds. "He's a right marvel." Annabeth laughed. "What? How many other kids snooze in two seconds flat?" Annabeth grinned.
