I'm not much of an audio book fan -- I'll read it myself, thank you -- but I just downloaded the audio version of Ranchero (read by actor David Carpenter), and it's funny and engaging in ways I never expected. Not the novel so much as Carpenter's performance of it. He's dead on, droll, and hilarious. Carpenter does all the voices, and they sound just like I heard them in my head when I was writing the book. I was expecting to be bored and a little put off, but I spent the last hour cackling at my own stinking novel. I couldn't be more surprised or gratified.
Bravo to David Carpenter! I might have to rethink my audio book aversion.
