The guardian's forbidden mistress

Nick Coleman had made it to the top the hard way - from rock bottom. But now he was one of Sydney's most eligible and handsome billionaires. The memory of his impoverished childhood only served to remind him that life was tough and so was he - he would never let a woman touch his hardened heart. But he couldn't do the same with Sarah. He had promised her late father he would act as her guardian and protect her. But he wanted her badly. Sarah's twenty-fifth birthday and her inheritance were only weeks away, and she needed to wise up to the predators out there who'd be waiting for a rich but innocent girl like her. Perhaps it was Nick's responsibility to teach her personally how wicked and seductive a man could be?
