Your long-winded retired Aussie academic brings you yet another updated and lengthened book challenge from a credible source. At least 1.7 million votes have been cast so far.
As described by Amy Boal at Ranker: "There are some books that you will just never finish, no matter how many times you try. Maybe the authors of these hardest books to read are laughing at all of us right now, or maybe they didn't even mean to make the book so tough, but here we all are, slogging through these book swamps, trying to figure out what the hell James Joyce is even on about with Ulysses."
Do you (vehemently) disagree with any of the choices?
Note: It isn't clear from the source list whether item 167 should be 'Night Watch' by Sergei Lukyanenko or 'Night Watch' by Terry Pratchett.
