A rich teen hopes that participating in a reality TV show set on an uninhabited Brazilian island can rehabilitate her damaged reputation.Twenty teens are dropped on deserted Black Rock Island, where they will compete in two teams for a cash prize and the chance to find a long-lost stolen Inca treasure. Riley Ozment knows all about the treasure, as her godfather was the last hunter to get close to discovering it-in fact, she visited the island with him shortly before he was murdered. She sees this trip as a chance to prove herself to the world after a series of mistakes led to her suspension from her private school and the very public humiliating fallout when she tried to defend herself. But Riley's plans are upended by back-stabbing, double-crossing, mysterious accidents, and her own inner demons. This thriller mixes the ins and outs of filming a reality show with a mystery, a side of romance, developing friendships, and, above all, Riley's journey of self-discovery. However, the convergence of all these disparate storylines doesn't form a cohesive whole, and the supporting characters are not as well developed as the protagonist. Interestingly, Riley is unlikable for her naïveté about her privileged background but still sympathetic as a teen girl finding her place in the world. Riley is assumed White; other competitors are described as being "Indian, African American, [and] Asian."An uneven novel that is as flawed as its protagonist. (map) (Thriller. 14-18)
