Los Angeles police detective, Harry Bosch, has been placed on The DROP, (the Deferred Retirement Option Plan) and is facing retirement in three years. But never one to slow down, Bosch seeks challenging cases to test his mental, physical and moral strength. Good for Harry! He gets two new cases: the DNA match of an eight-year-old boy associated with the rape of a teenage girl in 1989 and the surprising death of a city councilman’s son who was pushed from a hotel window. Connelly tightly twists the two cases, still giving a light touch of family, romance and many unexpected snafus. This is the 17th book in this police procedural which began with , the Black Echo.

>The double story line made this book interesting as well as the development of the relationship Bosch has with his daughter.
