Query: Will not work on a kindle without $15 a month!

This book is a favorite of all three of my boys. We are traveling and looking through the kindle store it was available. Too bad for us, we are unable to read or listen to a book we found using the kindle, because I am not a member of yet another $15 a month waste of money. If this is ONLY for listening, it should not come as a choice to one-click purchase on my kindle. I was given an option to join a club or buy separately... why give the option if there really isn't a choice. I am disappointed Amazon. Kindle books should be available to be read on the kindle.
