Stephanie and Allie have a great way to double their Christmas fun. They're planning to spend every minute of vacation together! But then James comes along, visiting relatives on Stephanie's street. James is cute, James is cool, and Steph is set to be his number-one date. But so is Allie! And there's not much Stephanie can do about it.

Because Great Aunt Sophie is in town and she's taking up all of Stephanie's time. Something's got to give, before Allie gets James and Stephanie gets left out in the cold!
