FBI Special Agent Kim Otto and Carlos Gaspar's off-the-books assignment leads them to the surviving members of Jack Reacher's elite military unit. Five years ago, Reacher sorted and destroyed a team of arms dealers in Lee Child's Bad Luck and Trouble before he moved on. He made mistakes. Now, Reacher's bad luck and trouble legacy plunges Otto and Gaspar into the mine field of a grudge war between Reacher's fearless old friends and chilling new enemies. When Reacher's enemies take women and children hostage for ransom, Kim's relentless pursuit leads to deeper into the deadly war Reacher failed to finish. Mercenaries and Kim's unwavering heart push her through -- until she meets the wrong woman with nothing to lose.
