Query: Hard to put down

The 12th in the Harry Bosch series is the best one I've read so far, and they're all good. Took about 150 pages to get going but when it did it was captivating and hard to put down. Suspensful and a real page turner. Highly recommended. Connelly is the absolute best author in this genre.
