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.
I'm ready to download the next one in the series now. I enjoy the description that had me watching the action as a movie in my head.
yet again great action, good scenery, good storyline. will most likely purchase the next one
A thrilling, fast paced yarn.
