Today, I chat to multi-award winning author, Joanne Harris about writing realistic settings. In her latest book, Orfeia, is set in three different worlds - Contemporary London, Alternative London and the Underworld - and the settings are sublimely written where everything can change at the twist of a well placed word. So. Joanne knows a thing or two about this and the show is bursting with hints tips and advice to help us write settings that pop off the page.
