Find lots more (80+) lesbian and bi Christmas books on the Goodreads list!
Note: this is just a round up of the most promising sapphic Christmas books I have come across-I haven't read them all myself. I can personally recommend Mistletoe Mishap by Siri Caldwell and Christmas Days: 12 Stories and 12 Feasts for 12 Days by Jeanette Winterson. The Winterson title doesn't have a lot of sapphic content (only one story talks about her and her wife), but it's my favourite Christmas book: the stories feel like timeless Christmas fables.
