Different Seasons and 4 Past Midnight are also collections of novellas...material-wise I'm not sure how much tonal overlap there is...

Thanks I’ll check it out

Not as brutal. It’s probably my favorite novella collection from him. 1922 is a masterpiece imo.

Pet Sematary

If it Bleeds is a good one. Much tamer, but very good.

The darkness you seek? If you like it Darker…delivers. Just after sunset is pretty freakin good.

Night Shift or The Bazare of Bad Dreams?

So few recommendations here for Night Shift and I think it’s one of his best short story collections.

Nightmares and Dreamscapes
