Camp Half-Blood Confidential by Rick Riordan. Narrated by none other than Percy Jackson himself, and other favourite characters will be heard from, too. In response to an awful camp orientation video created by the god Apollo, Percy Jackson and other residents of Camp Half-Blood answer such questions as "What is this place?" and "Do I get to keep the T-shirt?" Newbies can check out the section on the Divine Cabins, read up on Magical Landmarks.
