The Bluff (Calamity Montana, #2) by Willa Nash, Denver Perry

As Calamity's newest resident, Everly Christian thought life in small-town Montana would be dull and tame-and she needs a little mundane after the last few chaotic years. But one night, boredom drives her to the local bar, where she finds herself sitting beside a handsome and mysterious artist.

The man is anything but dull and tame, especially in the bedroom, and when she steps out of his shower and overhears his conversation, life gets interesting again.

Reese Huxley needs a wife.

And why shouldn't Everly be the bride?

She's got her reasons for agreeing to the hasty nuptials-reasons she's keeping to herself. As long as she can stop herself from falling in love with her husband, she'll make it out of this sham marriage in one piece. But Everly has a weakness for wayward men, and the more Hux pushes her away, the more she realizes this bluff is anything but a lie.
