Meddling Kids - Edgar Cantero: horror-comedy genre fusion, going for (as the title suggests) a grown-up Scooby Doo type thing, and does a surprisingly good job mixing that with a Lovecraftian style of horror
Universal Harvester - John Darnielle: deeply unsettling, kinda a character study, very confusing, but if you like The Mountain Goats (same John Darnielle!) it'll be hard to put down
Haunted - Chuck Palahniuk: I'll throw a trigger warning in front of this one, one of the most disturbing and disgusting things I've ever read. Combines short stories and an overarching narrative very well, but it is a tough read for sure
Skeleton Crew - Stephen King: His best short story/ novella collection, it's got "The Mist" and "The Monkey" (two of my favorites by him) and is just a great insight into his shorter-form storytelling
