L ~ Longest Book You've Read
I listened to the audio version of The Count of Monte Cristo. I started with a free version from Librivox.org. I got about a third of the way through, but had to stop because having different narrators made it difficult to concentrate. I didn't know if I'd ever finish it.
Then I found a library version by one narrator, Fred Williams, who was excellent. Suddenly The Count of Monte Cristo was alive and well on my MP3 player.
The complete audio was 46:56:39. Yep, that's almost 47 hours, but 47 hours of a great adventure story.
I started War and Peace at the beginning of this year, but work was too busy and I only got a few pages into it. Maybe I'll be ready to start that one, soon.
