You can buy Zen, Mississippi right now on lulu.com and have a copy in a week or so.
I’m calling this a “pre-sale” because it will be another 6-8 weeks before it will be available for general distribution. That doesn’t necessarily mean you’ll find it on the shelf in your local bookstore, though I’ll do what I can. What it DOES mean is that you will be able to go in your local bookstore and ask them to order it, and they should be able to easily get it for you. It will also be listed on Amazon.com and Barnesandnoble.com and possibly other websites where books are sold.
Even then, I make a couple of dollars more if you buy it directly from lulu.com, but I’m not concerned about how much money I make. I’m concerned about the easiest way to get this book in peoples’ hands, and if ordering it from Amazon is what’s easiest for you, then that is just fine with me.
