Mercedes Fuentes, or Mousy Mercy as she often refers to herself, has buried herself in academia in order to avoid those frightening creatures that make up the other half of the human population: MEN! When an opportunity to pay off the majority of her student debt is offered to her by a family friend, Mercy has her doubts. But how can she refuse a weeklong date with a handsome man, at the end of which she will be nearly free of all debt? Enter the seemingly innocuous, over-worked oil tycoon Wulf Rheinhart, a man in need of a fake fiancée for a week in order to close a business deal with a family-oriented Texan. One charade leads to another in this fast paced car chase of a romance where no one is who they seem to be.
