Heather Whitestone's life is too full for romance. Twenty-four hours shifts as an EMT and time with her brother's family leaves precious few moments to worry about a man. Her priority: To pull down as much overtime as possible to save up and become a paramedic. The last person she expects to see when she rushes into the emergency department with a critical patient is her brother's best friend, the new doctor at the hospital. And the last thing she expects is for him to propose marriage.

Zach Miller has a problem. After an internship in Las Vegas, he returned to his hometown of Addam's Ridge, Ohio, for a position as an emergency room physician. He's barely had time to settle in when he learns that he's the father of a two-year-old daughter. He wants nothing more than to raise her in his hometown, but her Nevada grandparents are insisting on keeping her. His best hope to gain custody is to be married. And when he sees Heather with her nephews, he decides a business arrangement might be in order: A temporary marriage with him paying for her paramedic training as a reward.
