Sleeper, Volume 3: A Crooked Line by Sean Phillips
Holden Carver was a superpowered doubleagent working for John Lynch,the world's most calculating spymaster, until he was left out in the cold for nearly a year. Running from his own people, and living amongst the enemy has changed Holden. He's turned his back on the things he once believed in and truly embraced his dark inner self... Or has he? Now Lynch is back in Holden's life, and trying to bring him back to the side of the angels. But is it too late for Holden's soul to be saved? And if it's not, can Lynch even be trusted, since Holden is little more than a pawn in the great game of superpowered espionage?
