4.0

It was a good read with two exceptions. The switching back and forth was a major distraction for me in this book. Maybe because the switches were quick and short. It made keeping track of the characters difficult. Then the ending was not satisfactory. The crime was solved, but many other things were at loose ends and you were even left with a cliffhanger. Since it was 8 years between the last books, that's a long time to wait for resolution.
