This story was a little different take on the theme of post collapse and had a lot of realistic scenarios.
I loved listening to this it's a great book, and was narrated well would recommend to anyone.
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.
