Summer is headed to the Keys for winter break, but what should be a fun-in-the-sun holiday is becoming unbearable. Summer hasn't been able to stop thinking about her ex-boyfriend, Austin, since their summer romance fizzled, and she can't stand seeing him at the beach with his new girlfriend....

Now Austin is everywhere she goes. She's reminded of how much fun they had, how gorgeous he is, and what she really wants is what she can't have. Will it take a Christmas miracle for Summer to survive this holiday season? Or will the mistletoe work its magic?
