The Men of the Vault series continues with Johnny's story. After watching all his friends pair up and move on, Johnny doesn't have a lot going on in his life. He goes to work at The Vault, running the place with Asher and make sure the clients are safe. But safety can be a relative thing. Ronin is a good man. Well controlled and a prominent member of society in all aspects of his life, except for one. His only vice, a kink if you will, is that he likes to play rough. The Vault has always been a safe haven for him to fulfill his needs without judgment or fear. But that all changed when the man he was with had a psychotic episode and ran screaming from the room, completely naked and threatening to take his own life. What happened between Mateo and Ronin wasn't Ronin's fault. Mateo was dealing with a lot of demons and wasn't ready for the kind of scene Ronin needs. But Ronin can't forgive himself for what he did. He promises to never hurt another person again...but by denying the need inside him, he risks losing the carefully constructed walls of control in all the other areas of his life. Johnny is the only man who can break through to him before Ronin loses it all. But will it be enough for either man to get what they need?
