Query: An Excellent, Gripping Read

I picked up Lee Child's The Enemy based on a number of recommendations, but not really knowing what the novel would be all about. The Enemy is an excellent thriller/mystery and I can see why Child's Jack Reacher series has so many followers (but don't understand why there aren't more). This is an excellent, well-written novel, with enough plot twists to keep you interested, some out of left field, some you may figure out on your own, but none that will disappoint. The novel opens on New Years' Eve 1989. Jack Reacher is an MP who has just been reassigned to an army base in North Carolina, and investigates the death of a general in a motel nearby. It looks like a heart attack, but things aren't adding up. Other, seemingly unrelated deaths and Reacher's got to figure it all out. The ending is both satisfying and plausible. Very well done. Enjoy.
