From Percy Jackson: Camp Half-Blood Confidential: Your Real Guide to the Demigod Training Camp (Trials of Apollo)

Camp Half-Blood Confidential serves as a guide to the demigod training camp, created by Percy Jackson and other residents in response to an orientation video made by the god Apollo. The book addresses basic questions about the camp and covers sections on the Divine Cabins, Magical Landmarks, and Training Arenas. Beyond describing the physical facilities, the guide includes insider information available only from those who live at Camp Half-Blood. It reveals that campers do not always coexist peacefully, the camp is not run with perfect efficiency, and prophecies do not arrive with regularity. The book features stories from heroes who have lived at or visited the camp. Chiron introduces the book with a brief history of training drawn from his millennia of experience. The god Apollo also contributes words of wisdom throughout, as the demigod authors prefer to avoid being struck down.
