"Billy Summers es un asesino a sueldo y el mejor en lo suyo, pero tiene una norma: solo acepta un encargo si su objetivo es realmente mala persona. Ahora Billy quiere dejarlo, pero todavía le queda un último golpe. Y siendo uno de los mejores francotiradores del mundo, un veterano condecorado de la guerra de Irak, un auténtico Houdini cuando toca desaparecer después de finiquitar un trabajo, ¿qué podría salirle mal?" -- Page 4 of cover.

"When Billy Summers was twelve years old, he shot and killed his mother's boyfriend after he kicked Billy's sister to death. At 17, he enlisted in the army. At 18, he was a sniper in Iraq and involved in the deadly battle to recapture Fallujah. For nearly twenty years, he's worked as a paid assassin. He's a good guy in a bad job, and he wants out. He takes on a very complicated, very lucrative job that he hopes will be his last. He's got a perfect new identity lined up and a scrupulously orchestrated, flawless escape plan. And then something happens that changes everything for Billy. A stranger needs rescuing, and Billy sacrifices the safety of his own perfectly devised new life to offer her protection. And then the two of them--the most compelling and surprising duo in King fiction--set out on one last mission, to rectify the injustices of one extraordinarily evil man" -- Publisher.
