Idk I thought it would be fun to make a list
Queer witch books I remember reading
All graphic novels for some reason
The Witch Boy (and sequels) by Molly Knox Ostertag (these books are so good)
Mamo by Sas Milledge (okay, I don't remember this one very well - it's been a while since I read it - but I remember enjoying it)
Beetle & The Hollowbones by Aliza Layne (cute middle grade book with Halloweeny vibes)
Brooms by Jasmine Walls (historical fantasy; quite good)
Snapdragon by Kat Leyh (one of my all-time favorite books, and an especially good one for Halloween. One of the main characters is Jacks, a motorcycle-riding lesbian old lady witch inspired by Granny Weatherwax from Discworld.)
Mooncakes by Suzanne Walker (just read this one this September. It's very cute and fun, the art is beautiful, and I loved the characters. Features romance between a nonbinary werewolf and a witch girl.)
