I've given 5 stars which is a rarity for a Patterson book. I was somewhat skeptical on reading as his track record of late hasn't been that good. Not sure how much Patterson actually contributed to the writing, but, was pleasantly surprised just how great this book was. Fast paced, believable characters, storyline, suspenseful with a touch of humor. This is one of those "can't put down or wait to pick back up" books.
