During survival training in the Idaho wilderness, policeman Reed Shelton and his wife, Beck, are attacked and separated by unidentified creatures. It's up to Reed to launch a search for his missing wife. But first he must convince the authorities that what he saw was real. As the investigation kicks off, detectives try to make sense of the story through forensic evidence, DNA analysis, and scientific speculation. Meanwhile, Beck finds herself within an almost mythical wood of mystery, darkness, and peril. The creatures she encounters will rid her of all remaining delusions of a safe and knowable world. Bestselling Christian author Peretti weaves another adventure thriller with a faith-based twist.
