Every one of his "Reacher" novels is good. I have read them all, some twice. Right now I'm reading The Fifth Vial, By Michael Palmer. good so far.
I just finished the last Reacher book. I didn't realize it was the last one until I was done. I spent all morning trying to figure out what to read next. I went back to the fantasy genre which I read mostly. So I am reading Gardens of the Moon by Steven Erikson. I hope its good.
