http://www.fantasticfiction.co.uk/ If you go to this site and type in an author you have enjoyed previously you can find links to similar types of books toward the bottom of the page. It also lists the author's books chronologically, so if you are like me and have to read a series of books in order, it makes it easy to find the titles you want. Then it's a matter of finding out if the books you like are available in audio format. I put books/CDs on hold through my library via the internet, and it shows if they have the audio format available.
