The first in this series was pretty good, the second even better, and this one improves upon both. Thanks to the independent subplots, it almost felt like I was reading 2 or even 3 parallel novels at the same time without getting lost or confused by it. # 4 is already on my to-be-read pile. (# 4, "Hell's Aquarium", is currently the last in the series, although Steve Alten keeps hinting at a 5th - oh, and a prequel novella is out there, but only for electronic reader.)
I thought they dragged it out a bit could have been much shorter and still would be an exciting, thriller about Jonas Taylor, a paleobiologist who crossed paths with Megalodon eighteen years ago. Now he is middle-aged, with teenage children and a wife---strunggling to pay his bills. When he is made an offer he can't refuse but will live to regret. For those readers who love scary, action-filled scenes...they will love it.
Another great scary shark story, the megalodon 'Angel' on the loose. This will grab you from the beginning and keep you on the edge to the end. Even if you don't read about the Jonas Taylor family from the beginning each book is it's own story, there are references to the other books but you won't be lost and it will make you want to read all of the them as soon as you can get them!
