The Bait by N.R. Walker

When three men turn up in their sleepy little town of Tallowwood, Harry and Asher know something’s wrong. Not because someone could find them, but the fact that Asher’s informant and oldest friend, Yunho, failed to alert them. Messages and phone calls unanswered; Harry and Asher go to Thailand to find Yunho is missing.
Harry and Asher find themselves thrown back into the game of shadows and murder, in a race across the globe to find him and find who’s behind the kidnapping.
The list of their enemies is long, their web of entanglement even longer, and Harry and Asher are about to find out once and for all who is predator and who is prey.
