Some books that are $0.00 (not all the ones in the linked list are $0.00), maybe others can post more...
Alice's Adventures in Wonderland
A Tale of Two Cities
The Mysterious Affair at Styles
The Three Musketeers
Just a note, you don't need one of the new fires for these to work with Whispersync for Voice. You need to listen using Audible for iPhone (iPod Touch), Audible for Android or a Kindle Tablet and read with any Kindle E Ink reader, Kindle tablet or Kindle reading app...
Oh thanks for clearing that up. I guess it's just the reading, listening, and highlighting at the same time that requires the new Fires.
