Finn Brennan is used to his brother playing practical jokes, but this time he's gone too far—sending Finn a woman as a ranch hand. And not just any woman, but a Marine. When 1st Lt. Camilla Walker's commanding officer asks her to help out at his family's dude ranch until he returns from deployment, she never expects to be thrust into a mistaken engagement to his sexy, cowboy twin—a former Navy SEAL who hates the Corps. But before long, Cammie is wishing their fake engagement could be real. The Corps took Finn's father, his girlfriend, and threatened his naval career. He's worked hard for another shot at getting back to active duty. The last thing he needs is a headstrong, unyielding, hot Marine who not only tempts his bed, but soon has him rethinking his goals.
