While not the most gripping or memorable thriller of all time, I was pleasantly surprised by The Killing Tide. I was very critical of the first book in the series, mostly because I felt the characters in that book were underdeveloped, unlikable, and honestly kind of cheesy; the second book had a lot to make up for if there was any chance of redemption. I'd started The Killing Tide knowing that if the writing hadn't significantly improved from the previous one, I would have to give up on finishing the series. I was ultimately satisfied enough and will eventually continue onto the next.
To begin with, a lot of the issues I'd previously had with main character Deputy Marshal Alexa Chase were not so much a problem for me this time around. She was a lot easier for me to root for as a much more respectful and open collaborator with her partner, Special Agent Stuart Barrett. This approach was much more enjoyable as I felt it allowed me to connect more with each of them.
The hunt for the main suspect felt more exciting this time, too; it had the element of mystery that Killing Game didn't. Whereas we knew all along who the perpetrator was in Killing Game, it's a complete unknown in Killing Tide. The plot centers around the detective work Alexa and Stuart put into identifying and aprehending their suspect, whose character and motivations were a lot more fully fledged out and multi-dimensional than in the previous book.
I did have to roll my eyes as early in the book Alexa confronts a serial killer she was responsible for putting in prison. He refers to her (the former FBI agent and current US Marshal) as his "hero," making this the second serial killer in as many books to outwardly admire and idolize her in this way. A bit of cop-aganda is expected in a book like this, but I mean, come on...
Overall, I enjoyed this book more than I had expected to. Since I consider Killing Tide to be a big improvement from its predecessor, I would be willing to give then next in the series a chance.
