“Having visited the Fairy Glen in Betws-y-Coed, Wales, I can tell you that places which claim fairies and their kin don’t seem out of the question. Certain places have that magical feel, as if they transcend what we know of life and reach beyond it into other realms. As for fantasy reaching nonfiction best-seller lists, I always tell attendees at conventions and festivals that I write nonfiction about elves.”
