Roddy Doyle’s eleventh novel, Smile, is the kind of book that is difficult to talk about unless it’s with someone else who has read it; a powerful novel with an ending that forces you to look at the whole book anew. Waterstones got the chance to speak to him about the real-life event behind this book, his love of dialogue and his work to help the writers of tomorrow find their own voices. Smile is available now here.
