Though the island appears uninhabited, the kids can't shake a feeling that something about it is definitely not right.

And in its lowest depths churns a dark, deep secret. As the group delves deeper into this mysterious new clubhouse, their lives begin to intertwine in weird and dangerous ways. For something ancient has awakened . . . and it can detect not only their wishes and dreams, but also their darkest, most terrible imaginings. Do they have what it takes to face the shadowy secrets lurking within their own hearts? Told from alternating points of view, this pulse-racing tale from bestselling duo Ally Condie and Brendan Reichs is the start of a high-stakes, thrilling series about friendship and believing in yourself—and each other.
