When two Dominants battle for supremacy, who gets to be on top? Joelle Mitchell is determined to overcome the loss of her submissive husband by taking a chance on a wild job at Dommes by Night as Mistress Elle. His loss left her unable to fulfill her last wedding planning contract, and she knows if she doesn't get back on track soon, she'll have to give up on her dream. Self-made billionaire and bored Dom, Spencer Van Ignes, has lost his passion. He's desperate to find anything to reignite his fire. So when he stumbles upon a phone sex company specializing in Female Dominants, he can't resist calling in. Finally, a challenge. Jo thinks she's finally on the right path when a local Fortune-500 Company hires her for an event. But as soon as she meets the CEO, he seems intent on breaking her. He challenges her at every turn with his ridiculous demands, almost as if he has a personal score to settle with her. Battling wits with her not-so-submissive caller leaves Joelle breathless, giving her the outlet she needs to bite her tongue during the day job. Perhaps she can let him wrest control from her grasp, if just for a little while. But when her new boss and her Dominant caller end up being the same man, she knows she's made a terrible mistake that jeopardizes everything.
