I am mystified by all the 5 star reviews. I've read and enjoyed almost all of Michael Connelly's novels. Some I have read multiple times. I think he's a great crime novelist. That being said, this is absolutely one of his worst books. He uses a plot device that John Sandford used in a novel 20 years ago. That book is one of my all-time favorites. Connelly's attempt is mediocre and lackluster. Harry is shoehorned into the plot and again we are reminded (several times) that he is old and his health is an issue. He and Renee Ballard make numerous boneheaded mistakes while tracking a killer. It's so disappointing to see a favorite character treated this way. There are also a few ancillary cases that aren't interesting, as well as a long portion of the novel devoted to Mickey Haller's courtroom antics. Also, Renee Ballard is just not compelling enough to carry a series and her continued animosity for Olivas is boring. Her lifestyle choices are ridiculous. An LAPD detective sleeping in a tent on the beach? Just can't suspend disbelief about that. Ballard's case work on the late show isn't interesting and takes up a lot of pages in the book. If Connelly has lost interest in writing novels because he's been working on the Bosch TV show and his podcast then maybe it's time to take a break. I know I will be taking a break from buying his books.
