Xandra Bingley, Antonia Quirke & Salena Godden. What drives a writer to write an autobiography? What makes a memoir unique? And what is it about them that so appeals to publishers and readers? Three outstanding memoirists talk about their very different experiences of writing about their own lives. They are joined by Arabella Pike, Publishing Director of Harper Press and the event is chaired by Observer interviewer and writer Rachel Cooke.
