Just what the title says. Not poorly written books, but books where something about it made you scratch your head. Maybe someone can explain.

For me it's Huis Clos/No Exit by Sartre. I still don't understand how people know the characters are in hell. I first read it in French. And when people were saying the characters were in hell, I was like, "Say what?" I totally didn't pick up on it.

So I read it in English. Still didn't pick up on it. How do you know?
