New York Times bestselling author Mia Sheridan's twisted tale of one detective's pursuit of a serial killer who's tormenting her... and the familiar connection between them that haunts her. When Sienna Walker Almost Got Fired from the Police Force New York, the last thing she expects is a second chance in a place she vowed never to return to. But she can't afford to turn down the job offer, even if a painful family past and a broken engagement hardly make Reno, Nevada, home. What makes it even less enjoyable is Sienna's first case - a serial killer fixated on her. Along with his victims, the killer leaves behind cryptic clues and chilling diary entries addressed to Sienna, detailing the murders he claims were committed by his mother. The case becomes increasingly personal when the killer turns to her ex-fiancé. Whoever is behind these diabolical murders, Sienna can only be sure of one thing - it's someone close to home. The twisted truth forces Sienna to face her complicated feelings, and she realizes that no matter how far you run from your past , it always catches up with you in the end.
