A serial killer *texts* his victims first. A detective vows revenge. He comes after her. In the chill of an October night, Detective Kerri Blasco is called to a bizarre murder scene. Leda Winfield, a young volunteer for the homeless, has been shot. Her cell phone displays the frightening text, WATCHING YOU, and into her back, hideously pushed with a hat pin, is a note with the same awful message. Leda's socialite family and friends insist that no one would have wanted to harm her, but Detective Kerri isn't convinced. Until another random young woman is killed in exactly the same way. Kerri and her team profile a monstrous killer who enjoys terrifying his victims before stalking and killing them. But how does he get their phone numbers? Kerri soon finds that the killer is after her, too, and that the key to finding him may just be in the homeless shelter. When the body count rises, she vows to stop the madman - even if it means battling her own personal trauma, risking her job, her love relationship with her boss Alex Brand, and her life.
