I'm reading Dero Saunders penguin classic which I picked up from a used book store. It's fine, but I'm at the point where the last 6 books of the original should kick in and Saunders treats it as an epilogue. I didn't even realize there were multiple abridgements when I started, and reviews of the others seem to include more about that and retain more of that special "Gibbonness" that's been so much delightful effort to parse. It's been a slow and halting first read I'm looking forward to a more uninterrupted story the second run through. I'll probably go for the Wormesly one and try to spot the differences. You only really start to know a great book after the second reading anyway.
