The 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. . . .
