The Forgotten: John Puller series, Book 2.
John Puller is a clone of Lee Child’s Jack Reacher. Puller is a military cop too (but still in the service). Puller is not as tall or big as Reacher, but he likes to fight just as much. In this story John finds his beloved aunt dead in a town called Paradise. She was at the center of a mystery. John isn’t leaving until the mystery is solved and justice is served.. at the end of his fist or gun.
