I generally have several books on the go at the same time, including audiobooks.
Mostly I listen to new releases, but occasionally I go back in time. I recently made an effort with Catch 22, but didn't get far.
Right now I'm listening to Anne Tyler's Dinner at the Homesick Restaurant, which comes highly recommended. Seems like a good summer book, good for lying down and enjoying in a leisurely way.
I am a huge audio book fan. I am currently listening my way through the Patrick O'Brien Aubrey/Maturin series (all 21 books) and I listen to something non-fictional between each one. I just finished "As You Wish" by Cary Elwes, an excellent retrospective on The Princess Bride.
Two audiobooks I just can't seem to delete from my mp3 player:
I absolutely love The Uncommon Reader, a novella by Alan Bennett, read by the author: what happens when Queen Elizabeth II's corgis lead her to the travelling library parked at Windsor...
The Testament of Mary, a novella by Colm Toibin, read by Meryl Streep.
I've discovered Librivox, and am cruising my way through old classic sci fi stories. Last night I had fun listening to H. Beam Piper short stories, and next I'm going to 'read' some Murray Leinster.
I just finished Bradbury's The Illustrated Man. A great short story collection I likely would never have read in paper.
I just finished Elizabeth Moon's Sheepfarmer's Daughter. It lasted through a few road trips, and I'm itching to start the next book in the series.
Anansi Boys by Neil Gaiman, which I enjoyed. With all the animal voices and accents it was a good one to do audio instead of print book.
And for falling asleep, re-listening to At Home by, and read by, Bill Bryson. The book is actually pretty interesting-- one of those history through a particular narrow angle books (in this case his house), and I listened to it the first time mostly while conscious, but the combination of detailed descriptions, lack of anything resembling plot, and his voice, makes it really a perfect sleep aid.
