I'm beginning to get used to the idea of one book having two themes/plots. I still think they should be separate, but I know better than to beat a dead horse…
This book had a new main character, and she's good. There were again to concurrent stories, but the combination was not as jarring as is sometimes the case. The two stories were both important and complete. There was nothing hanging at the end, and Michael Connelly has regained his position in my good graces! The book was not obvious, but it was definitely consistent. Good job.
