I actually had a long solo drive this past weekend for the first time in a long time. Took the opportunity to listen to the first 5 hours of the audio book of The Upstairs House by Julia Fine.
The narrator in the book has a new baby and an unfinished dissertation on children's literature. She is very ambivalent about both of those things. The result is that Margaret Wise Brown's ghost (author of Goodnight Moon and Runaway Bunny) has moved in upstairs.
There's just a touch of horror, and I'm not exactly sure where the story is going in the final third. I'm almost reminded of Victor LaValle's The Changeling, which is maybe my favorite horror fantasy novel, so that's a good sign.
