The Girl Who Ruined Christmas — Cindy Callaghan

Award-winning middle-grade Christmas novel from the author of Just Add Magic and Saltwater Secrets . . . . 
Imagine you're a tween visiting a small town that loves nothing more than its prize fir -- a perfect Christmas tree destined for the White House. Now picture yourself accidentally destroying that tree, making you public enemy number one. Lastly, imagine that to repay your debt, you have to remain in said town for the Christmas season.

That's what happens to Brady Bancroft.

When Brady ruins Harper Hollow Fall's prize tree, she's sentenced to stay in the holiday-festooned town for the month of December. At first, she couldn't be more depressed about the whole situation; but during her month there, she is surprised to discover that there's much more than pine needles to the little town holding her captive. In the end, Harper Hollow Falls reminds Brady of the true meaning of Christmas -- and she, in turn, saves the town.
