The "ski instructor" beautiful, innocent Milly Mayfield thought she was giving herself to in a sumptuous, secluded French ski chalet! And now she's livid!  Arrogant playboy Lucas is bewildered by Milly's decidedly unusual reaction to the revelation of his substantial wealth—he's never had complaints before! But even Milly cannot ignore the sexual chemistry between them. So when a family emergency means he needs a willing woman by his side, Milly suddenly finds herself whisked away to Spain…and engaged!
