I was using up all of my accumulated credits on Audible.com just now, and realized I've listened to several great audiobooks over the last year. Here's a list of what I've listened to in 2011, along with a link to the book on Audible.com. I recommend them all.
Judas Unchained, Peter F. Hamilton, Part 2 of the Commonwealth Saga (link)
The Gun, C. J. Chivers (link)
The Windup Girl, Paolo Bacigalupi (link)
Snow Crash, Neal Stephenson (link)
Embassytown, China Mieville (link)
Pattern Recognition, William Gibson (link)
Spook Country, William Gibson (link)
Zero History, William Gibson (link)
I'm pretty excited about my reading list for 2012 (and likely beyond--I had 12 credits to use), which I will share soon.
