Everyone knows that Amazon is by far the biggest book seller in all formats, so of course the DS Pete Gayle books are on there, in both e-book and paperback formats. But I am aware that some people don’t like e-books and some don’t like Amazon. So, for that reason, the books are also available on a variety of other platforms as well. They are all on Apple Books, Barnes and Noble, Google Play, Kobo, Lulu and Smashwords as e-books. The first three of the series are also available as paperbacks wherever Harper Collins sell their products, including high-street retailers like Waterstones. Book 4 onwards are on Amazon as paperbacks internationally and on Lulu.com as paperbacks in the UK only. They are also now on Amazon.com as well as Google Play as audio books. Books 4 to 13 are on Barnes and Noble in paperback format for international sale but, for now at least, they won’t allow me the ISBN codes for the rest of the series.
