I recently read the second book in a thriller series, called "Dead List: A Thriller" (Amos Carver Book 2)
I have to admit this book was much better than the first book, which I found to be bad and boring. This sequel actually has an interesting plot and setting (Miami - with a high end party crowd) and the hero in the book has a very skilled fellow assassin after him, for once. (and in a nice twist, its a female assassin, and in close combat she is even deadlier than he is) (whereas in the previous book, the main hero guy was untouchable to the point of being absurd - no competition - and so a rather dull "thriller" type book)
The fighting scenes were pretty good in this book, especially the male assassin/hero vs female assassin showdown. I also am reading a kind of "extreme" horror book, which is kind of unpleasant, because it involves a rather grimy subject, but that said, I have to admit, the writer is a good writer.
There is a thriving "extreme" horror genre now on Amazon, most of it just "gore porn" with graphic over the top scenes, designed to make people feel nauseous when they read it or something... but this book, I found, is different. Despite the low-rent type of horror plot, the writer knows how to write compellingly. It's the kind of book where you want to keep reading it, it keeps you interested, despite the very unpleasant subject matter that its about. This writer actually has good taste, in that he knows not to put in too much of the nastiness like in other books typical of this genre - in other words, he understands "restraint".
