After decades of being the world's top hired gun, Michael Bullets needs a vacation. But when he steps aboard a plane to the island of St. Joseph the Lesser and comes face to face with the world's second-best killer, Pistols Wickett, he realizes he might miss his appointment for that beachside massage.

It's all-out war as Bullets faces the secretive Third Hand network, the treacherous Baker's Union, his former partner in a fast casual sea urchin restaurant, a scuba-diving cannibal, up-and-coming killers looking to grab some glory, a deadly game of tiddlywinks, and more, leading toward the final confrontation with Wickett. It will be his toughest mission yet: saving his own life, confronting his souring legacy, and trying to keep his mostly mechanical body running, all while keeping his promise to never kill again--though no one said anything about handing out a multitude of butt-whuppings.
