This is the story of a descent into Hell, still being read over 700 years after it was written. Whatever your religious beliefs, Dante wrote about a journey common to many; the downward spiral we can only escape from when we finally reach the very bottom.
The advantage of the D.L. Sayers translation is its readability. Miss Sayers was a best selling author; like Dante she knew how to keep the reader interested in the story. Her translation isn't always 100% accurate (which is why this edition gets four stars, and not five). But the technical accuracy was generally sacrificed for the more exciting read - if you want to read Dante for your own pleasure, this is the version to get.
