I can't summarize the plot without spoilers so I will only say that it follows two threads: tracking Harry Bosch as he testifies and helps the DA out during a sensational murder trial and re-introducing Terry McCaleb of "Blood Work" who takes on a profiling assignment as a favor for a friend.

The two threads eventually tangle up in surprising ways and also eventually untangle in equally surprising ways. Connelly's characters are, as usual, flawed but in non-fatal ways. I am in awe of his ability to crawl into the heads of his characters as they struggle with their own morality and mortality.

While undemanding of the reader, this book is, nevertheless, a fascinating story and well worth the time to read.
