I read pretty much anything, from fantasy (City of Stairs by Robert Jackson Bennett) to romance (Bared to You by Sylvia Day) to classics (Heart of Darkness by Joseph Conrad). The only genres I don't read are self-help and comic books/graphic novels.
According to the introduction, this is a book that no normal person would be able to fully, or even partially, understand on the first reading. I can't imagine many people even making it all the way through the first reading, I certainly didn't. I'm sure it's a great and important 19th century piece of American literature, but the pages long stream-of-consciousness style Faulkner used became incomprehensible and very tiring to read. The blurb on the back of the book makes the plot sound interesting, but the stream-of-consciousness style in the second "chapter" along with the strange back and forth "time travel" between different unnamed times made it almost impossible to follow, I was just reading the words, not comprehending the story. I have taken his other works off my list of books to read.
