Guardian's Forbidden Mistress

An Australian billionaire playboy is ready to pounce on the one woman he can't have in this romance from the USA Today-bestselling author. Nick Coleman was one of Sydney's most eligible billionaires. Love 'em and leave 'em that was Nick's mantra. But he couldn't do that to Sarah; he had promised he would act as her guardian and protect her. Yet he wanted her, badly. . . . Sarah was soon to claim her inheritance. She'd be a sitting duck to predators looking for a rich, innocent girl. Perhaps it was Nick's responsibility to personally teach her how wicked and seductive a man could be. . . .
