Meet two writers whose new books have set the critics alight. Catherine Chanter's The Well is a gripping thriller built around a house that harbours some troubling secrets. Emily St John Mandel's sparkling Station Eleven is George R R Martin's favourite novel of the year. It is a story of love and nostalgia, 20 years after a flu bug has wiped almost everyone out. Both novels are set to be award-winning bestsellers.
