I have to ask for those who read the divine comedy: Did anyone else get through the Inferno, start reading Purgatory and quit reading? The Inferno was awesome, then it felt like Dante quit trying. I even skipped forward to Paradiso thinking Dante saved the best for heaven. Nope. Boring.
This version may be relevant to the modern reader, especially if you like SF. It's inspired by Dante's version and shares the topology, much of the background, but is a lot lighter overall (not to mention shorter) than the real thing.

"Inferno is quite literally a cake walk through , with a science fiction writer as Dante and Benito Mussolini as Virgil. I kid you not, Pournelle and Niven have had the chutzpah to re-write Dante's Inferno as if they were some unholy hybrid of Roger Zelazny, Robert Heinlein, and Phil Jose Farmer. You are right there in the nether-reaches of the ultimate Sam Peckinpah movie with all the matter-of-fact solidity of a Hal Clement novel. It gets to you, it really does. This being lunacy of a transcendent order."--Norman Spinrad
Interestingly Niven and Pournelle released a sequel in 2009 - odd as their "Inferno" has been out for 20+ years.
