I love a good Christmas books thread, so let's have one 
I'm currently reading Winter Solstice - bought it last year in the Kindle Christmas sale specifically to read during this run-up, after seeing so many people here rating it so highly.
I'll also re-read The Mistletoe Bride by Kate Mosse - I love a good ghost story at Christmas. Which is why I'll also be re-reading all the Chilling/Thrilling/Mysterious Christmas Tales books - they're 90s children's/YA books but I bloody adore them, they're the ultimate comforting, nostalgic Christmas read apart from the Megowl which can sod right off
Christmas Carol, obviously. And maybe a bit of Sherlock Holmes.
Any other recommendations? I've just decorated the house and curling up with my Kindle, coffee, mince pies and twinkly tree lights is one of my favourite things about Christmas
