Don't Know Jack (Hunt for Jack Reacher #1) by Diane Capri
FBI Special Agents Kim Otto and Carlos Gaspar need the help of rogue ex-military man Jack Reacher, now a wanted man. But is he their friend or foe?
It's been a while since we first met Lee Child's Jack Reacher in Killing Floor. Fifteen years and twenty-one novels later, Reacher still lives off the grid, until trouble finds him, and then he does whatever it takes, much to the delight of readers and the dismay of villains. Now someone big is looking for him. Who? And why? Hunting Jack Reacher is a dangerous business, as FBI Special Agents Kim Otto and Carlos Gaspar are about to find out. Otto and Gaspar are by-the-book hunters who know when to break the rules--but Reacher is a stone-cold killer and a wanted man. But whose side is he on? Only secrets hidden in Margrave, Georgia, will tell them.
