I just started listening to audio books on Audible.com during the past couple of months. I wasn't sure that audio books would be for me, but I find that I really enjoy listening to stories. Professional narration makes all of the difference. I do like some authors reading their work; I find I'm in love with Michael Ondaajte's voice. 

Here's my current line-up:

 

River Town by Peter Hessler

 

The Looming Tower by Lawrence Wright

 

Team of Rivals by Doris Kearns Goodwin

 

The Cat's Cradle by Michael Ondaatje

 

Revelations by Elaine Pagels

 

I'm also trying out Amazon's whispersync on some of these books. It allows you to move back and forth seamlessly between audio and digital form. That comes in quite handy.
