Tripwire is a classic Jack Reacher story. This 3rd book in the series follows the usual plot line of Jack being pulled into some injustice despite minding his own business.
The book opens with Jack digging pools in the heat of Key West and ends with him convalescing in a New York hospital. Somehow, Jack's hard physical labor in Florida saves his life in New York. (Read the book to find out how. No spoilers here!)
Tripwire's injustice involves beautiful childhood friend Jodie, now a successful lawyer, a missing in action Vietnam veteran and a Peter Pan like hook. An enjoyable romp if you care for the genre. A bit of a trope if you don't.
