The obvious nonfiction pick here is the Bible 🙂
Fiction is a little harder to pick, partly because there is so much fiction (especially Christian fiction) featuring Christmas. Some authors feature Christmas in all their stories because it’s popular all the time.
I can see the appeal, although I prefer summer stories. Lots of authors combine to produce Christmas collections. My favourite was the An Aussie Summer Christmas collection, where all the novellas were set in Australia. As a Kiwi, I loved the summer Christmas stories 🙂
I have read a couple of Christmas stories in recent months, although some are more “Christmas” than others (if that makes sense). My favourite was You Make It Feel Like Christmas by Toni Shiloh, which is an expanded and republished version of I’ll Be Home. Click here to read my review.
I’ve also recently read and enjoyed All Fair in Love and Christmas by Sarah Monzon. While it centers around Christmas, I read it during the New Zealand winter to get the seasonal feeling. But it’s still centered around Christmas, with a neurodivergent main character and a fun workplace rivalry. Click here to read my review.
