The best Christmas present

From a reader mom:

"Rapunzel's Revenge and Calamity Jack brought our Christmas present opening to a 10 minute full-stop. The girls were so engrossed they hardly acknowledged our presence. It took a lot of coaxing to get them to continue opening gifts! Thanks for helping feed my girls' love of reading with your excellent books!! Merry Christmas!"

EDIT: I just realized that the title makes it sound like I'm claiming that my books are the best Christmas present. What I meant was that the best present for me was hearing about these girls who loved the books! Shuffling myself off now...
