The teenagers of Maggie's Knee have been vanishing without explanation, their disappearances blamed on everything from adolescent rebellion to "shadow people" in the woods.
Farren Murakami, an eighteen-year-old who has suffered more than most, finds out first-hand where the youth have gone when she's recruited to join a tribe of teens living in an abandoned camp hidden deep in the woods. It isn't long before she learns there is more to the story than just runaway kids; a sinister presence dwelling in the forbidden buildings tucked far back in the camp seems to have handpicked her for its purposes.
In her search for answers, Farren discovers her involvement with the tribe goes farther back than she can imagine, and that whatever lives in the forbidden buildings wants much more than the fealty of some kids playing in the forest.
