Hi, due to driving a lot I listen to audiobooks and the odd play sometimes, and I love it. I will listen to just about anything but like to listen to things that I wouldn't necessarily read.
Most recently I loved: Anna Karenina The Moonstone (although I've read it about a hundred times - I won't be listening to The Woman In White though) John Grisham - The Last Juror - excellent and I wouldn't really read his books. The Woman In Black - Susan Hill (scared the crap out of me, even though I've seen the play)
Not so good John Grisham - The Appeal Guillermo del Toro - The Strain (er, really not sure why, don't read it and don't listen to it, unless you are really into vampires)
I have struggled with historical audiobooks such as biographies.
There's a great American author, Lilian Jackson Braun, who writes a series of books called "The Cat Who...". They're mostly murder mysteries, based around a reporter living in New England with his Siamese cats. They're very "easy listening", and you can more or less pick one at random as they are all self-contained and you don't need to read them in order.
I love audio books when driving, ironing etc The narrator is really important though as some voices just grate on you. Titles I have enjoyed recently and would recommend are The Kite Runner by Khaled Hosseni read by him too, The Cutting Room by Louise Welsh read by Robert Carlisle, The Shipping News by Annie E Proux can't recall the narrator but was fab. Loreli King is quite good too but it's often modern american stuff which is not always to my taste.
