I just put on an audiobook, almost sure it was this one. And it may have been hard to understand at first but I didn't care, I was just talking a long walk and decided to leave it on, and by the end I was understanding everything and it was a pretty cool experience.
I have not tried to actually read his books. I actually just got started with reading Alan Moore's "Providence", graphic novel series. What I have is a collection of all of his graphic novels in that universe I think, it's a huge, very heavy book. My copy is in Spanish (link), not sure if this exact collection exists in English but as an English author all his graphic novels are obviously available.
Anyway, I wish I had more time to try and read his works. I just found a download link for 13 of his books for free on Project Gutenberg.
