Unfortunately, the book is not available for purchase on Amazon US and UK. Instead, it shows as "the Kindle title is not currently available for purchase." It's happened a few times in the past that people login into their account and notice that the majority of their books have vanished.To purchase Kindle books, you can select the device or app you want the book sent to in the deliver to: drop-down. This guide focuses on books downloaded from Smashwords, but the information is equally relevant no matter where you're getting them. Go to Your Account then click on manage digital content. You will then see a list of all the books you have bought or downloaded for your Kindle. Before you make your ebook available to the public, make sure you have a tax identification number. From the Digital Orders tab, select the Return for Refund button next to the title you want to return. Amazon states quite clearly that you cannot turn off 1-Click ordering for Kindle books. It's very intentional.
