Family drama at Hay Festival

In front of an audience at this year’s Hay Festival Helen Lewis talks to three prize winning authors about their work. Damon Galgut’s Booker-winning The Promise tells the story of a family and a country – South Africa – and the failed promises that destroy them both. The exciting promise of a super-connected world where memories are currency is set against the quest for privacy in Jennifer Egan’s new novel The Candy House. And Margo Jefferson examines every passion, memory and influence – from family to jazz to art – in her new memoir, Constructing a Nervous System. Producer: Katy Hickman
