This is the third book in the Alex Delaware thriller series by Jonathon Kellerman. This I did not feel was as R rated, few scenes but still for a mature audience. I did enjoy the novel. It has good pacing and lots of twists as you unravel the plot. Presented in a believable fashion that keeps you very engaged. If you are looking for good read this would be a great choice, but be aware that this is book deals with death, homosexual topics, murder, sex, and similar topics.
