Here, I propose you a very interesting list of audiobooks put together by Oprah's Book Club People.
The list includes a good variety of audiobooks for all kind of readers. For instance, there is:
(1) The Snow Queen by Michael Cunningham with Claire Danes as narrator.
(2) I Am Malala: The Girl Who Stood Up for Education and Was Shot by the Taliban by Malala Yousafzai with Archie Panjabi as narrator.
Listening time for these audiobooks varies between 3 to about 11.5 hours. Here is the link (click here) for Oprah's suggestions.
