Cultures and Beyond (The Art of World Building, #3) is available!
That said, the paperback, hardback, and audio book are ready but it sometimes takes a couple days for Amazon to have them go “live.”
I was once again able to get Piers Anthony and Ed Greenwood to review the book, with Ed having giving his comments already:
“Ellefson continues his masterful overview of worldbuilding, carefully and coherently dealing with every last detail that Creating Life and Creating Places haven’t covered. All three are essential reference works. Ellefson is a master of this craft, and it shows. Highly recommended!”
