I have just tried Brad Thor for the first time, and love his book(s). I just finished The First Commandment, and read it almost straight through. The characters are both easy to feel part of you; that you love, hate are afraid of and afraid for the characters you don't want hurt...but you know are going to be.
I have already bought two more books. And, I'm so glad Brad Thor seems to be a very prolific author. I'm sixty nine and am planning on reading all of his books. I read most of the time and I hope to enjoy the rest as much as the first.
