Ten years ago my novel, A Tangle of Roots, was published in paperback with a price tag of more than £8. It was a POD release. Today, the story has been reissued as The Long Road to Sunrise in Kindle format for £1.96. An example of how technology has made a book purchase very much cheaper. You need an Amazon Kindle to make the download, of course, but the ubiquitous Kindle seems to be everywhere these days. If you have one, use it, and you don’t have to spend a lot of money to buy e-books.
