"Spine-chilling and creepy!" --Max Brallier, #1 New York Times bestselling author of The Last Kids on Earth, on Escape From Grimstone Manor (Monsterious, Book 1)

When her small town is rocked by a series of baby kidnappings, Teo vows to spend her summer break solving the mystery, and convinces her friend Logan--who would much rather spend his vacation relaxing--to help.

Their search for answers soon leads them to the woods at the edge of town, and Teo fears some kind of supernatural creature might be behind the snatchings. What else could explain the creepy figure they see moving through the trees, or the bloodcurdling screams coming from the forest at dusk?

Logan has his doubts, but when another child is taken, there's no time to waste. Can he and Teo get to the bottom of the kidnappings and rescue the missing babies before it's too late?
