The night little Madison disappears from her crib, Luce sees a pair of eyes-two points of gold deep in the forest behind her house-and feels certain they belong to a wolf. Her town, Picnic, Illinois, is the kind of place where everyone knows one another and no one locks their doors. It's not the kind of place where a toddler goes missing without a trace, where wolves lurk in the shadows. In town, people are quick to blame Madison's mom. But when Luce's English teacher shares an original script about the disappearance of another little girl in Picnic back in 1870, Luce begins to notice similarities that she can't ignore.
