Gracie “Ace” Adams is dealing with a lot for a teenage girl: overwhelming depression, a traumatic loss that’s tearing apart her family and her social life, and a terrifying shadow man who haunts her each night as she tries to sleep. When she stumbles across a black cat in distress, the appearance of the strangely intuitive animal provides the first comfort she’s had in months, and Ace starts looking for answers to her problems. Soon, she realizes that everything--her new furry best friend included--might be connected.
As her search begins to yield some strange results, Ace’s nighttime visitations from the mysterious shadow man take a violent--sometimes bloody--turn, leaving her with physical reminders of her paranormal encounters. Can Ace and her loveable feline sidekick figure out what this spirit wants and how to get rid of it before it takes over Ace’s life, or worse, kills her?
