How do you hold on to heaven? There's an angel watching over cowboy Trey Wheeler. After a nasty accident during a snowstorm last spring, a mystery woman saved Trey's life…and disappeared. Since then, he's been looking for his sexy savior. Now the Last Chance Ranch crowd has taken over the Serenity Ski Resort for a Christmas wedding and Trey realizes there's something familiar about the exquisite ski instructor…. Elle Masterson has no halo—just the love of her footloose-and-fancy-free lifestyle. And when she finds out the sinfully hot cowboy she rescued is staying at the resort, she's happy to indulge in a little holiday hanky-panky. Just as long as she can still take off for Argentina in the New Year. But after three days of heaven between the sheets, will this down-to-earth cowboy be able to let his guardian angel go?
