Any suggestions for fantasy science fiction audio books?

Best Answer - Chosen by Asker: Try these (most of them can be found at Recordedbooks.com or Amazon.com):

Ender's Game by Orson Scott Card
Berserker by Fred Saberhagen
Battlefield Earth by L. Ron Hubbard (the movie was horrible, but the books is a lot of fun)
Doomsday Book by Connie Willis (this is an incredible time travel story)
Invasion of the Body Snatchers by Jack Finney (classic sci-fi thriller)
Time and Again by Jack Finney (another great time travel novel, with incredible attention to detail--a great mystery story, too)
