The Library at Mount Char came from a Reddit recommendation for weird/bizarre fiction, and it did not disappoint. It's about kids who were abducted by a very powerful person, and that's all I'll say about it. If you like house of leaves or some of the strange chuck palahniuk stuff, you'll like this.
I also read The Library at Mount Char this year. I picked this up off the shelf at the library somewhat randomly. I didn't know anything about the book and so I was a bit skeptical. It took me a while to crack it. But wow, once I did...this is one of the strangest books I've ever read. Super messed up. But it was hard to put down.
