Lachlan Byrn just couldn’t unsee it.
It began as a routine paid kill, but then the assignment became a crusade.
Over the years Lachlan Byrn has evolved the act of turning his back on problems that don’t concern him into an artform. So, what’s different this time?
Byrn finds himself immersed in the sordid world of human trafficking. As dark as the assassin's nature is, the activities of those he's charged with hunting down do not sit well with him. The killer's own moral compass is challenged, yet he seems determined to deal with the low life operators he's been tasked to eliminate, no matter the personal cost.
As if the shear magnitude and power of the forces he's facing aren’t challenging enough, Byrn discovers that he’s working for a dead man. Yet step by step, death by death…
It appears you can’t keep a good man down… or a bad one.
