Kim Iverson Headlee lives on a farm in the mountains of southwestern Virginia with her family, cats, fish, goats, someone else’s cattle, half a million honey bees, and assorted wildlife. People and creatures come and go, but the cave and the 250-year-old house ruins—the latter having been occupied as recently as the midtwentieth century—seem to be sticking around for a while yet.She has been a critically acclaimed author since 1999, channeling Mark Twain since 2007, and a student of Arthurian lore for more than half a century.
