Being one of Santa's elves isn't all sugar plums and candy canes.At least not for Sosie. Taller than the other elves, she's always had a problem fitting in at the North Pole, so when the transport sled she's on breaks down in New York City on Christmas Eve, she can't resist slipping away to explore the world of the "big people." While she's having fun, the transport sled takes off, leaving the naive elf stranded.Fortunately, handsome police detective Derek Clayton comes to her rescue, offering to let her stay at his apartment. Having heard horror stories about the big people, Sosie is both surprised and relieved to meet such a kind, sweet man. Not to mention one so gorgeous and well-built.Even though Sosie expects the North Pole to send out a search party any day, she finds herself falling for Derek anyway. She desperately wants to tell him she's an elf, but knows he'll never believe her. When the lies and omissions start to pile up, Derek can draw only one conclusion - Sosie is working for the mob boss he's been after for years.Just when things seem like they can't get any worse, the chief of elfin security shows up to drag Sosie back to the North Pole. How is a runaway elf supposed to overcome a determined security elf, dangerous mobsters and a suspicious boyfriend all while keeping her pointed ears a secret?
