The Changelings (War of the Fae Book 1)

Jayne Sparks, a potty-mouthed, rebellious 17-year-old and her best friend, shy and bookish Tony Green, have a pretty typical high school existence, until several seemingly unrelated incidents converge, causing a cascade of events that change their lives forever. With a group of runaway teens, Jayne and Tony are hijacked and sent into a forest, where nothing and no one are as they seem. Who will emerge triumphant? And what will they be when they do?
