One of my favorite Christmas authors is Melody Carlson. I know she writes non-Christmas fiction, but I've never read any of them. Her Christmas stories are fun and inspiring.
Debbie Macomber is one of my favorite authors. I've read her fiction, her non-fiction, and her Christmas stories. She's an author that I run to the bookstore to purchase her new release the day it is published!
I read Christmas books year around, whenever I'm in the mood for a little Christmas spirit!
