Is anybody else thinking that it will definately be Annabeth or Percy that stays behind. I mean, the description that Amazon gave us it said Leo wonders how Percy and Annabeth will escape.

I'm not just basing this of that description, but at the end of The Mark of Athena, Frank asked Nico if they could maybe get them both back safely, and Nico said maybe. I just think that it is going to be one of those two...
