Antihero

Two problems: A tech-billionaire whose psychological crisis could have catastrophic implications for the global order. And the abduction of vulnerable young woman, Anca, seized from the New York City Subway, held, hurt, then discarded like trash.
One solution: Evan Smoak, a former black ops assassin codenamed Orphan X, now dedicated to helping the desperate with nowhere else to turn.
But saving the world from a powerful man who has lost his mind while pursuing justice for an innocent survivor will test Evan like never before. Especially when complicated by Anca's inconvenient insistence that he show some measure of mercy to the men who abducted her.
Because if the world's greatest assassin cannot kill, then this mission just got a whole lot more daunting and dangerous.
As lethal threats mount, Evan may have to choose between upholding a higher code . . . and his own life.
