House of Windows by John Langan (The Fisherman, lit-horror short story collections).
Finished up John Langan's first book from 2009. Like The Fisherman and his short stories, it's very much a high-lit book. A haunted house story where the two main characters are English Professors. It's pretty lengthy and a good deal ambiguous, and falls much further on the lit genre side than the horror genre side, but in exchange you get a very well written book with well developed interesting characters. It's creepy at parts, but it's more a drama about relationships, family, etc... that has some creepypasta mixed in.
I wouldn't say it's one of my favorite horror books, but it was worth the page count and always enjoyable to read thanks to Langan's excellent writing. Very good 3/4 book. I'll definitely check out the couple of remaining short story collections of Langan's that I haven't read at some point. I very much enjoy his output.
