The paperback versions of "Rock and Roll Love Story: The Two Volume Set" and its follow-up "The Beach" will remain on sale until Halloween. After that, the books will be exclusively available in the Kindle e-Book store on Amazon for $2.99 and 99 cents respectively.
I think the paperbacks are too expensive for what they are and despite the relatively high costs, my own profit after the retailers take their cut is so small that's it's really not worth me trying to market the paper books anymore.
You do not need to buy a Kindle to read the Amazon e-books. Just download the free reader app for your computer, smartphone or tablet and go to it!
