Pulitzer Prize-winning Michael Chabon said ‘great literature respects no borders or boundaries’. Stephanie Merritt talks to him and two other writers whose work challenges and extends traditional notions of form and genre. Mark Haddon’s The Curious Incident of the Dog in the Night Time has won more than seventeen literary awards in five countries, including the 2003 Whitbread Book of the Year, and was the bestselling novel of that decade by a British writer. Eimear McBride’s debut, A Girl is a Half-Formed Thing, is bold in style and breathtakingly intense and won the first Goldsmiths’ Prize in 2013.
