A Christmas Seduction — Amanda Browning

The millionaire...
Being forced to spend Christmas with his godfather's mistress was not Quinn Mannion's idea of fun. Laura Maclane might be beautiful, but Quinn had no doubt she was a heartless gold digger. Why else would his godfather have left money to an attractive younger woman?

...and the mistress
Laura had never wanted money -- she'd just wanted to get to know her father. Unfortunately, now that he was dead, who would believe she was his daughter? Certainly not Quinn. Infuriated, Laura decided to play up to his expectations of her -- and soon Quinn wanted her as his mistress....

Hero: Quinn Mannion
Heroine: Laura Maclane
