The 11th Harry Bosch novel marks the detective's return to the LAPD after nearly three years of retirement, when he joins a unit of 'closers' who specialize in using new technology and improved police techniques to find the answers to long-unsolved cases. His first assignment at the Open Unsolved unit involves the 1988 kidnap/murder of 16-year-old Rebecca Verloren. DNA found on the gun proves to be that of a white supremacist, suggesting that Rebecca's biracial heritage may have prompted the killing--a possibility which, curiously enough, was not pursued during the original investigation. In the course of his inquiries, Bosch discovers hints of a police conspiracy, and also learns just how much and how painfully Rebecca's death affected the future course of her parents' lives.
If you are looking for a story that grabs you from the first chapter and is so exciting that you can't put it down, this is not the book for you. The pace is very slow and plodding. Probably more realistic in the pace of the story but if that is not the kind of book that interests you, choose another book.
