When I was ten or eleven I read this series of children’s books in Urdu featuring a boy who travels with snake charmers and has a pet snake. He and his snake have many adventures. Subsequently I dreamed about becoming besties with a snake or two for years. I’ve been fascinated by them ever since. The Indian subcontinent, of course, has many myths about snakes who assume human shape after a hundred years. I wanted to write a story about that. The research and details naturally followed.
