Don't judge a book by its cover, they say. And yet of course, that's part of the decision making process for many of us. Lots of thought, work and talent go to creating a memorable cover, and our guest this week knows that better than most. Charis Loke is an illustrator whose work appears in and on books, magazines and games, and she joins us to discuss her process and inspirations. We also talk about the art of making maps for books and our favourite book covers.
