Describe the plot of the next book you want to read, even if the book doesn't exist yet.
I'll just describe the one I intend to read next, since I'm not creative enough to make anything up about a book I'd like to read that hasn't been written yet. It's a detailed history of the neo-Pagan subculture. It talks about rituals, lifestyles and the people who practice neo-Paganism. It was the book that helped me realize that what I believe has a name & that I wasn't alone in the world believing that way.
