Our family has been using Audible since 2006, and subscribers since 2011; we have quite a stash of audiobooks!  We have used Librivox occasionally, but I find that the quality and ease of use keeps me coming back to Audible.

Below are our favorites, based on story and narrator (narrator in parentheses).  I’ve listed them (roughly) in order of maturity.

If you are using Audible credits, make sure to look for the biggest collection of a series you can find.
