Dealer of Secrets by Davidson King

If you have a secret you don’t want anyone to know, Zaire Vicario can find it. And if it’s worth something? Well, that’s currency to him. When things get desperate, the shadiest people call him in, and he makes their troubles go away with all the knowledge he’s acquired. He’s confident, powerful, and ready for anything. At least, he thinks he is. All it takes is one evening at The Anonymous and a man cloaked in lies to change Zaire’s whole world.
Carter Merrill enjoys his life healing people. As a traveling nurse, he brings light to a dark and gritty town. Until one phone call changes all he knows and all he is in the blink of an eye. Carter has never used his hands to harm, but when his twin brother is brutally murdered, he makes the decision to uncover who did it and seek revenge. The only problem is, he has no idea how to do that. When a stunning man approaches and offers to help, Carter has no other option but to walk into the lion’s den.
Deep dark lies, unrelenting lust, and dangerous liaisons thrust Zaire and Carter into treacherous territory and unfamiliar circumstances. They find their lives connecting, as well as their bodies, when one secret reveals layers of atrocities neither of them ever expected. Can they survive the savage storm ahead or are they doomed to the same fate as Carter’s brother?
