Nate the Great and the Crunchy Christmas by Marjorie Weinman Sharmat and Craig Sharmat illustrated by Marc Simont*

I introduced Nate the Great to my first grader this weekend and he devoured the four books we own in a day and a  half!  We have requested more Nate the Great books from the library.  This is his review:
"I liked it because they cannot find a card for Fang.  His mother sends him a card every Christmas.  He gets the card but he scares the mailman.  He buries the card underground and then Nate the Great and Annie find it."
