Lee Sullivan has really got her life together, as the mayor's publicity chief and the respected Domme, Mistress Star. She doesn't foresee any bumps in her life until she meets Branch Colby, self-made millionaire and a man who pushed her buttons. She has no idea that he is a full-out Dom who sees women as a challenge and this one more than most. When Branch's friend Max bets him he cannot get Lee to submit to him, Branch agrees to a high-stakes wager. The problem is he never expected to fall for her or what the consequences would be when she learned the details of the bet. He has to find a way to repair the situation, and she has to decide whether giving her heart is worth the risk.
