Rainbow's End — Rebecca Forster

Life seemed perfect for Bridget Devlin. Her first nursing job had transported her from a provincial Irish Village to the sophisticated world of San Francisco's moneyed elite. She hadn't anticipated that the family matriarch who had been placed in her care would become a warm and welcoming friend...or that she would secretly lose her heart to the dowager's handsome grandson. But then the elderly woman died - and left the bulk of her vast estate to Bridget. the family's reaction was swift and cold...and suddenly life wasn't so perfect anymore.
Richard Hudson suspected the blue-eyed Irish lass worshipped him from after, and while he carefully shielded his emotions, he grew to love her in return. But now a sudden millionairess, the once warm and caring Bridget had turned indifferent and aloof. Was she unaware of the real reason behind his grandmother's surprising bequest...or had she been a cold and calculating fortune hunter all along? He realized only time would tell if she would learn that life's greatest legacy was love!
