Sometimes salvation comes from the most unlikely hero. When Tate Gillespie is marked for death for a crime he didn’t commit, his life crumbles. In a world where "justice" is meted out by a relentless military force, he’s going to need more than a mythical guardian angel. His life down to seconds, he’s saved by the mysterious X, a knife-wielding man he's never even met before. But who is X? Is he the man who threatens and kills without a second thought? Or the strangely gentle man who only seems to act that way around Tate?

When I gave up life as a hitman, I thought everything was going to be better. I was going to become a PI, help people, and live normally…and then I met Jeremy, the most perfect man to have ever saved my life (I mean, he might be the only one who has saved my life, but he’s still the best at it). From that point on, it was all over for me - I knew we were meant to be. The issue is that he doesn’t…quite seem to realize that. But when he’s targeted by criminals (literally, someone just shot at his head), he needs to rely on someone, so why not me?
