I read this the first time when I was somewhere between 16 and 20, I think. But to be honest, I understood fuck all about it then. I only re-read it now, several university degrees later and after 2 more decades of reading, and pheww... this book, this author: so far ahead of its/his time: structure, voice, topics, everything is so different from things that came before. And now I can see how much authors that came after him owe Faulkner. 
 Only now I can place this in the proper context. 
 What an overpowering book this is.
