In the Woods
The book: In the Woods by Tana French (No. 1 in the Dublin Murder Squad series)
The hook: Three children go missing, but only one is found — a boy with blood-filled sneakers who lost his memory of what happened in his state of shock. That boy is now a detective who must return to his hometown to investigate a murder with similarities to his own unsolved mystery.
Fear factor: Children being murdered in the woods is a recipe for an eerie piece of literature, and this one will raise the hairs on the back of your neck.
