Authors James Runcie and Naomi Alderman and the editor of The Bookseller Philip Jones join Mariella Frostrup to discuss the literary trends of 2012. Themes include EL James's 50 Shades of Grey and the rise of the bonkbusters, Hilary Mantel's historic second winning of the Man Booker Prize and what that means for historical fiction, and how self-publishing is helping to change what and how people read.
