A spooky or eerie story that’s atmospheric and involves lots of details about a house…BUT

Here's the kicker: I don't like stuff that's too scary, gore is a no-no, and I'd prefer a happy or at least hopeful ending.

The "fear" should come more from the atmosphere and maybe the backstory of the house.

Here are some suggestions I don't want:

Rebecca–I already know what happens
Turn of the Screw–I've already read it (plus it's a short story, I'm looking for a novel)
House of Leaves–I tried to read it, but I couldn't handle the formatting.

Thank you!
