I did,t feel the character development was very strong, though the story line seems fine. Not a big fan of the language used in the novel. The robbery and tunnel rats description could have been more gripping and leaves a lot to the imagination.
Usual semi-predictable climax which might disappoint if you are expecting an ecstatic one.
*SPOILER*
In the end you realize that Bosch is again one of those goody-goody, moral stick stuck up his ass, kind of a guy, which is not for me. I would prefer if Bosch had intentionally shot the Dollmaker and sympathetic and appreciative towards Wish and her plan to take down the assholes who killed her brother.
Overall not very impressed with the novel to continue with the series. So, time to jump to next thrillers in search of Dexter or Jason Bourne kind of a character...
