In today's Read On, Robert Kirkwood chats to the Map Men, also known as Jay Foreman and Mark Cooper-Jones about their debut book This Way Up - When Maps Go Wrong (and why it matters). In this first part of a two part show Jay and Mark talk about accents, breaking the fourth wall and addressing the listener directly and about turning a very visual book into an audiobook. Plus we'll find some festive books in the RNIB Library.
