Trained Marine sniper Nathan McBride is the sole survivor of Montez de Oca, the brutal Nicaraguan interrogator who tortured countless souls to death before vanishing fourteen years ago. Though McBride's body--as well as his soul--still bear the scars from the interrogator's blade, he dares to hope the worst is behind him.

But when the FBI recovers a mutilated body from a remote Utah lake, McBride needs just one glimpse to know the truth: Montez de Oca has resurfaced, this time on American soil. And McBride will be damned if he lets him escape again. So begins a quest for justice that will push McBride to the edge, pitting his capacity for mercy against his hunger for vengeance in a deadly game of cat-and-mouse that will reach into the highest levels of the US government.
