Mandy and the Cowboy Mogul (Colorado Dreaming #5)
Angela Claire

Aidan Munroe has just taken over the railroad his family owns. When Mandy seems intent on seducing him, he decides to play a part himself, pretending to be a simple cowboy looking for work and claiming he just doesn't believe in "having relations" before marriage. He doesn't know what he enjoys more—the incredulous look on Mandy's face or her blatant attempts to disabuse him of the concept.
Will Mandy and Aidan ever stop playing their parts long enough to fall in love?
