Her Missouri Master by Karen Nappa

A woman with a past. A man guarding his future. It’s the perfect arrangement — until it isn’t.

Trust is the one commodity Zeren Demir can’t afford to waste. And when it comes to the women lining up to be the next Mrs. Demir, he refuses to spare an ounce of it.
Until he meets Marian, a woman who guards her heart more closely than Zeren guards his fortune. The contract they sign at the exclusive Club Zella seems like the perfect answer for both of them. Zeren can punish and pleasure his gorgeous new submissive at his whim without risking more than he’s willing to pay.
But with every scene, he grows more invested in learning the secrets she keeps so carefully tucked away. By the time he is through, he’ll know everything there is to know about Marian Jenkins — or he’ll lose her forever.
