Books with great plot twists that are NOT thrillers or mystery novels?

I've been reading a lot of thrillers lately because I'm craving twisty and surprising books such as The Last House on Needless Street and Agatha Christie's novels, but I'm starting to get a little burnt out and losing interest in the mystery genre.

To avoid that, I would like to find books with good plot twists that don't strictly belong to those categories. Stuff like The Marriage Portrait (historical fiction), On The Savage Side (more literary fiction than thriller), Sign Here (a mixture of horror and paranormal fiction) and so on. Thank you in advance!
