Welcome to the Dungeon
Amazon is a huge storefront, not just for books of all genres but you can search, find, a purchase a variety of products via their one little search bar. It's easy, you can even use that search bar to find your favorite erotic books by your favorite erotica authors with some exceptions. The dungeon used by authors to describe when their book can no longer be found using the All Products on Amazon's website. The books listed below are by JACKL authors that are still for sale and in KU, but you can't find them via the main search page.
If you're searching for books on Amazon, always remembers to select "Books" or "Kindle Store" in the search bar.
