Santero is a rookie officer who reeeeealy wants to make detective. When a serial killer pops up in true area Santero‘s chief enlists his old partner, Rein, to help them. Rein is pretty damaged and broken after some events that went on while he was still a detective. Can they stop him before more people are killed? The book moved at a good pace and kept me interested the entire time. I listened to the audio book and the narrator was excellent.
