Is she his worst nightmare.... No relationships, that's billionaire Garth Solen's rule - especially not with a woman like his new employee Melissa Bencher, who thinks with her heart and not her head. But all bets are off when Melissa's attempt to make her jerk ex-boyfriend jealous by suggesting that she's dating Garth. To protect his ailing grandmother, he is forced to play the part of Melissa's adoring fiancé - or a dream come true? Melissa couldn’t begin to imagine all the trouble one impulsive act could cause. Now she's trying on rings and posing for the paparazzi with her gorgeous boss. The game is clear: for one month, they play the part of an engaged couple, and then they part ways. No emotions. No entanglements. But when it comes to matters of the heart, Melissa's never been good at following the rules.
