Keely McKay knows Jack—and Jack Donohue is a certified pain in her Wranglers. The lone girl in the prolific McKay family, Keely needs another man giving her orders like she needs a hole in her boot. What she does need is a restoration specialist so she can open her physical therapy clinic—and prove she’s left her wild-child days behind. That means dealing with buttoned-down, uptight Jack.

Jack is this close to securing a career make-or-break project, until he learns his lack of marital status puts him out of contention. When the notoriously hot-tempered and hot-bodied Keely begs him for help, he proposes a crazy idea. He’ll oversee her project—if she acts the part of his loving fiancée.

Their sizzling lust makes it all too easy to go from butting heads to knocking boots—but outside the bedroom they’re as mismatched as ever. The McKays remind Jack of the humble upbringing he left behind, and cowgirl Keely feels she doesn’t measure up to Jack’s big-city lifestyle.

When the dust settles, Jack and Keely must face the fact they’re not fooling anyone but themselves—or they’ll risk losing the real deal.
