There are currently two free audiobooks from
Zondervan available for download. Both are in mp3 format. The first, "Unlocked" by Karen Kingsbury, can be found at BooksOnBoard
here. The second, "Hostage in Havana" by Noel Hynd, can be found at GoBible
here.
Neither of these books are Christian-based (in the sense they are not about the Christian religion), but they are written somewhat from a Christian viewpoint so they have some elements of faith in their perspective.
Hope you enjoy!
