Although Camp Atropos used to be a camp for Fair Children, it is now a camp for kids with special talents. If you have read Lisa Graff's earlier book, A Tangle of Knots, you know a talent is something you are really good at, better than anyone else. But you better watch out. There are those who would love to steal your talents, to make money off of them.
So, while a camp for kids with special talents may seem innocent enough, the director has plans. Using an artifact she had since childhood, she has the ability to mimic each child's talent, and then sell those talents. Of course she makes money doing this, but the kids retained their talents, so no real harm done. Right? All goes well until she discovers that one of the campers has a special talent that she wants for her own, a talent that will help build a bridge between her and her estranged sister. As she goes after that talent, chaos erupts in the camp when everyone's talents are mixed up and a special talent that has fallen into the lake puts them all in peril.
One cabin of campers, however, cabin eight, may be the only hope to saving everyone's talents and stopping the camp director from stealing what isn't hers. In order for this to happen, however, the cabin mates have to learn to get along with one another. There are two sisters, known as the frog sisters, who have the ability to identify every kind of frog imaginable, and one even claims she can talk to frogs; two brothers, one who is allegedly able to read peoples minds, and the other who seems to be a fair child (talentless), and then finally Lilly, a Pinnacle, a girl who can levitate items, and who wants nothing more than to be first in her brother's heart. But with a recent accident that she caused, and a step sister who has the exact same birthday as her brother, she finds she's being pushed aside and forgotten too often. Can the differences between these campers be set aside to save the campers?
