When Adam Park's former mentor recruits him to locate a vulnerable loved one, he learns very quickly that the girl is either the victim of an ex-con's manipulation or the brains behind the robbery of a major criminal enterprise. Whatever the truth may be, she is in mortal danger.

Tracking the pair from the UK to Paris, then Paris to Asia, Adam delves into the murky and violent world of human trafficking and extortion, where he must draw upon the darkest corners of his psyche to survive. But these are facets of himself he has long denied exist. Bubbling just beneath the surface, Adam has kept his anger and violence caged all his life. Because he's a good person. Isn't he?
