Calculating Christmas — Kristee Ravan

A month after Lily and Calo rescued the characters from Cinderella and The Candlemaker's Daughter, they've been assigned to a new case. Santa's rebellious daughter, Carole, has had enough of her family and needs a change. And if that change isn't handled carefully, it could wind up derailing Christmas for everyone -- a fact the will equal lots of unhappy citizens potentially vanishing. So, no pressure for Lily, right? Wrong. In addition, Lily is dealing with the ever-increasing demands on her time, leaving her very little time for her beloved math. Multiply that by the fact that she can't seem to please her parents, her friend Corrie is mad at her, and her unsolvable relationship status with Calo, and you're left with a pretty stressed out Lily. Will she and Calo manage to save Christmas? Will Lily find a way to be the Princess the kingdom expects? And how will things turn out with Carole, who is openly naughty in front of Santa Claus?
