Maeve Fly by CJ Leede - very dark humor but set in the happiest place on earth. After that I'll pick up a horror novel, it's that time of year.

I'm currently reading the new Michael Moorcock, Woods of Arkady, with new Justin Cronin novel The Ferryman on deck.

Last Days by Brian Evenson has really stuck with me, one of the best and most creative in the 'cultist' subgenre. Also seconding Negative Space by BR Yeager.
