The latest version of Audiobook Wizard supporting OSX Lion is available for purchase for $4.99 from the Appstore. Hit this link to go there. Version 1.1 continues to be free and you can download from C|NET download.com. Click on this direct link or search download.com for Audiobook Wizard.  Do note this version supports Snow Leopard and lower version of OSX only.

Do consider purchasing the latest version from the Appstore though. It will help to support my work on Audiobook Wizard. Besides, it is twice as fast and simply better!
