Need some Christmas season joy

Okay, bookish people, it's coming to that time of year again. And this year, I'm in need of some escapist joy during a not-so-joyful time for me. Holidays are hard for a lot of us. So, hit me with your best Christmas book recs! I'm looking for pure Christmas joy and magic. Any genre — I love a good fantasy, magical realism, romance, whatever. Just make 'em happy and joyful, like a hug from the universe. I need to believe in holiday magic again.
