Twins, Luc and Logan Ramsey, are Doms. They run Club Mystique, the BDSM club they co-own with their three brothers. They agreed to remain single until age thirty-two. When they meet secretive Cassandra "Cassie" Edwards, Logan decides she's the woman for them, but Luc decides she has too many secrets and refuses to get involved with her. Cassie blames herself for her father's death and has protected the people she loves by distancing herself from them, until she meets Luc and Logan. Tempted by Logan, who pursues her at every turn, and intrigued by Luc who wants her but keeps his distance, Cassie has to decide if she can be their temporary sub without endangering them. All bets are off when Luc and Logan discover the secrets she's been keeping and decide to protect her from the men who abused her and killed her father.
