As usual in MIchael Connelly's books, there's more than one mystery. The book, however, seem to only have space for one, causing things to feel a little rushed.
The attempted surprises seemed pretty obvious to me.
Overall, it was entertaining, but less than previous books.
The best thing for me was that I bought a Kindle e-book that came with an Audible narration. When I needed to stop reading and run errands, I could just pop the book in my car and keep listening. It was cool how Audible synchronized with Kindle - I popped my phone in and it started exactly where I had stopped on Kindle.
