Catherine "Cat" Chandler is a smart, no-nonsense homicide detective, who is haunted by her own tragic past. When she was a teenager, Cat witnessed the murder of her mother at the hands of two gunmen. Cat would have been killed too, but someone – or something – saved her. No one has ever believed her, but she knows it wasn’t an animal that attacked the assassins...though it was strange and terrifying, it was human.
Years have passed, and although she thinks about her mother every day, Cat is now strong and confident, a capable police detective working with her equally talented partner, Tess Vargas. The two women make a good team, and have become close friends while working on countless homicide cases under the supervision of their tough-but-fair boss, Joe Bishop. Cat has also become close to another co-worker, the medical examiner Evan Marks, and they’ve developed a fun, flirtatious relationship that could easily turn into something deeper – if Cat would let that happen. However, much to the concern of her younger sister, Heather, Cat’s romantic inclinations tend toward bad boys...
