“With a creepy and menacing undertone and one of the scariest antagonists ever, this is sure to give readers nightmares. Cummins excels at raising the level of dread and suspense, and this unpredictable, impossible-to-put-down read is dark, gripping, and eerie . . . for fans of Karin Slaughter and those who love well-written psychological thrillers.” —Library Journal (starred review)
