What are your favourite non-Christmas books, adult or childrens', that have good Christmas chapters or scenes in them?
Here are a few that I thought of, beyond the really obvious ones like the first chapter of Little Women, or the Little House books (addition: or The Wind in the Willows):
Almost anything by Jean Little: she practically made it a trademark to end her novels on Christmas (or in one case, on St. Nicholas Day). From Anna is one of our favourites and, I think, one of her best Christmas chapters. (There's an excerpt from the beginning of the book at that link.)
The Middle Moffat, where Rufus gets a letter from Santa saying, "Sorry, all the ponies are at the war."
The Five Little Peppers
The Fairy Doll, by Rumer Godden. This book could be called a Christmas book anyway, but it's not all set at Christmas time.
Ballet Shoes, by Noel Streatfeild
The Ark, by Margot Benary-Isbert. This book actually has two good Christmases in it, and I'm not sure which one I like better.
Anne of Green Gables, but also Anne of Windy Poplars, where Anne reluctantly takes her grumpy co-worker home with her for the holidays.
Last but not least: Father Christmas's appearance in The Lion, the Witch and the Wardrobe.
