Maps have the power to transport us, filled as they are with wonder and possibility. Here, internationally acclaimed writers and illustrators share their personal insights, encompassing not only the maps that appear in their books, but also the maps that have inspired them and the sketches they create in writing. Philip Pullman recounts a map he drew for an early novel; Robert Macfarlane reflects on his cartophilia, set off by 'Treasure Island'; Daniel Reeve describes working on 'The Hobbit' films; Miraphora Mina recalls creating 'The Marauder's Map' for 'Harry Potter'; David Mitchell leads us to the Mappa Mundi by way of 'Cloud Atlas'. And there's much more besides. Amidst a cornucopia of beautiful images, including unpublished sketches by authors, there are maps of the world as envisaged in medieval times, maps from classics of literature and cherished stories, as well as maps of adventure, sci-fi and fantasy, from Atlantis to Westeros, Narnia and Utopia, from Mercator to Tolkien.
