When social worker Hildy Schneider commits to an after-hours side job, she finds herself drawn into the darker side of small-town Sorenson, Wisconsin-and the twisted mind of an unnamed killer . . .

Strange things have been happening since Hildy started moonlighting with local police, but a desperate late-night call involving a former patient from Sorenson General Hospital tops the list. Although Danny Hildebrand has been tormented by hallucinations for years, he swears he's being haunted for real by the victim of a grisly murder . . .

The rambling ghost story seems like another delusion. But after a body turns up in a neglected farmhouse crawling with secrets, Hildy and the magnetic Detective Bob Richmond rush to explain Danny's knowledge of the incident. As the crime-solving partners unwittingly grow closer while examining a series of eerie leads, they realize that surviving past sunrise means shedding light on a criminal willing to do whatever it takes to stay in the shadows . . .
