We just listened to an incredible reading of Endurance, Ernest Shackleton's adventure in the Antarctic. I hear that another Endurance, Scott Kelly's memoir of his life as an astronaut and on the space station, is also excellent (and read by the author).
AJ Jabos' books (The Know It All, The Guine Pig Diaries, The Year of Living Bibilically) are fun, funny, and interesting. Though I can only listen to his voice for about 20 minutes at a time.
Munro's What If? is a good listen, as was a The Disappearing Spoon. We tend toward the geeky and memoirs in our family lol. Those two books were good when I was driving kids to school.
Gary Sinise (local boy!) reading Steinbeck's Travels with Charley was really good.
Other memoirs we liked include Steve Martin, Nora Ephron, Carol Burnett, Julie Andrews (that voice!), Martin Short, two by Amy "Ask Amy" Dickinson, and a couple by (local gal) Jen Lancaster.
You can get Terry Gross' NPR Fresh Air interviews on CD. Also NPR "Driveway Moments" and an NPR anthology of animal stories, they were a good listen.
We get all our audiobooks on CD from the library...free.
