Alice fell down a rabbit hole to Wonderland. Dorothy was whisked away to Oz by a tornado. Wendy, Michael, and John flew away to Never Land with Peter Pan, and Harry Potter could just go to Platform 9¾ whenever he needed to enter the wizarding world. Literature is full of examples of children who stepped (or fell. Or were dragged) into one of many different variations of fairyland..
Some children when they return are happy to have escaped alive. Most grow up and remember their adventure as a childhood daydream. A few get to stay in fairyland forever. Seanan McGuire’s Hugo-nominated novella Every Heart a Doorway is set in Eleanor West’s Home for Wayward Children, a school for those travelers who’d do anything to go back.
