I never thought I'd write this sentence....
My audio book just dropped this week on Audible.com
It's a bit of a surprise, but I'm happy that it came out, and in my initial listen, it seems pretty darn good! There are a lot of images in the book, but you can still get most of the book through the text. THAT's a huge surprise. Still, not bad!
Check it out. The Joy of Search... Audible style. (And, at that link there's a sample you can listen to.)
