Like many readers, maps in books have always fascinated me. I once knew someone who collected books only with such maps. One of the most famous maps, the treasure map found in Stevenson’s Treasure Island, was drawn first, and the story written around it. One of my own early books, Who Stole the Wizard of Oz?, a mystery, has, as its primary clues, maps from well-known childrens’ books, The Wizard of Oz, Winnie The Pooh, Treasure Island, Through the Looking Glass, and The Wind in the Willows. My book was inspired when I came upon an atlas of fantasylands. What a book by which to travel! This comes to mind because my forthcoming book, Sophia’s War, will have not just one map, but two. Such maps not only illuminate the story, but seem to give a singular sense of reality to a narrative. In a very special and literal way, maps provide a way of following a story. Or perhaps the best stories follow a map to explore new worlds.
