Something sinister is happening in Crooked Oak. Ever since the fracking site closed, Nancy's parents have been acting weird. Their eyes are blank, they won't eat--it's like they're no longer themselves. Before she knows it, the symptoms begin affecting others as well. Nancy enlists the help of her best friends, Pete and Krish, and the trio of Crooked Oak middle school students resolve to find out what's really going on. But the deeper they dig, the scarier the mystery gets. A dark presence is spreading its tendrils across their home. Can they stop it before it takes over the whole town? A spine-tingling supernatural middle-grade adventure, perfect for fans of R. L. Stine and Margaret Peterson Haddix.
