Mark Powell doesn't cheat because he's unhappy. He cheats because he likes it. The secrecy. The control. The rush of getting close to the edge without ever going over. Sherri was never supposed to be anything more than convenient- someone willing, eager, and easy to keep in her place. But she's starting to want more, and Mark is beginning to push boundaries he never thought he would. At home, Sophie remains unaware-secure in a marriage built on years of love, trust, and shared history. Until one night changes everything. Because sometimes the most dangerous part of an affair isn't getting caught- It's believing you won't.
