I went to Denver yesterday. When in Denver, I go by the Tattered Cover bookstore because they're one of the few places who actually has one of my books. I take Gunslingers & Ghost Stories and turn it face out so people can see it better. So far, it hasn't made much difference. People just do not want to buy it. Still, I do what I can. Just remember, most stores list anthologies by the title, not by the name of the editor.
I sure wish a mob of 20,000 people would descend on the Tattered Cover and order my book. I'd even settle for a mob of two people. That's how many copies they have.
