The Bourne Identity meets Minority Report in this first highly anticipated installment in number-one New York Times best-selling author Kim Harrison's sexy new romantic suspense trilogy, featuring a brilliant special task agent at the top of her field and set in a futuristic Detroit.

During a routine but dangerous Opti task, Peri Reed finds out her trusted partner has made her a corrupt agent. Her unique ability to jump back 40 seconds in time to correct a mistake leaves her vulnerable when her partner, who is responsible for replacing her memory of the event, gives her a false one. But Peri lives and dies on her intuition, and she begins to piece her twisted reality together as she flees her one-time secure situation at Opti and tries to find the truth with a sullen but talented psychologist named Silas who works for the very agency trying to bring the Opti corruption to light.

With Howard, tech and med specialist, and Taf, gun-toting daughter of the opposing grass-roots agency, Silas and Peri try to rebuild her memory of the night she killed her partner, knowing it will put her mental stability in danger. Peri remembers, and thoughts of revenge keep her alive and moving forward as she tries to put an end to Opti, working with the very faction that wants to see her dead.
