Her Sexiest Mistake by Janelle Denison

Grey Nichols wants a lover, not a wife. But after he meets beautiful Mariah Stevens, he can’t get her out of his mind. Lucky for him, she isn’t out of his bed much, either! In fact, he’s so captivated by her, he considers the unspeakable—asking Mariah to move in with him.
Mariah Stevens wants a husband, not a lover. No matter how incredible the nights are with Grey, she needs more. So she gives him an ultimatum—no more private pleasures without a public ceremony. But resisting Grey is much harder than she ever imagined . . . and if she’s not careful, he might just become her sexiest mistake . . .
