Not just on Amazon
Yes, Amazon is the go-to place for authors.
However, I have now expanded to other platforms. You can get the book on sites such as Smashwords . This offers a larger distribution to places such as Apple Books, Barnes & Noble , the Smashwords Store, Scribd, and Kobo , OverDrive (world's largest library ebook platform serving 20,000+ libraries), Baker & Taylor Axis 360, Tolino, Gardners (Askews & Holts and Browns Books for Students), Bibliotheca CloudLibrary (3,000 public libraries), Odilo (2,100 public libraries in North America, South America and Europe) and Califa's Enki (powers ebook checkout systems for over 100 Califoria libraries)
So go get my books at the Smashwords website.
