There are many reasons why a book might be unavailable.
Sometimes a book goes temporarily out of print - and sometimes no audio version has ever been recorded. Audible wants to give you the most complete selection we can and we'll keep adding series and filling in gaps as quickly as possible.
The performer made me cringe every time Maddie spoke. I learned to dislike Maddie because of it. Very painful and unnecessary.
Listening to the performance of Maddie is painful--fingernails on a blackboard. I can't grasp why it was allowed.
I like the story line and love Maddie, she so sweet and fresh always adding something extra.
