Evan Nichols likes his nice, quiet life in Boston. An established and respected Dom in the BDSM scene, he isn't looking for a sub, a slave, or a 24/7 relationship. Then a phone call from his best friend and fellow Dom, Rhys Calhoun, shakes up his comfortable routine. Rhys needs Evan's help to rehabilitate an abused sub-a sub Rhys has fallen in love with. Evan has misgivings, but he could never say no to Rhys, any more than Rhys would ever refuse to help him. Before he knows it, Evan finds himself at Rhys's home in Las Vegas with a sub who can barely stand to be in the same room with him and a Dom whose emotional involvement threatens his control. Add in the sexual attraction that's always simmered between Evan and Rhys, and it's a situation that has the potential to go very, very wrong. Determined to heal both Takoda and Rhys, Evan doesn't realize how many assumptions about his own life will be called into question as he tries to help them find their way forward together.
