  McCarthy is the only shortlisted author to have been nominated before, having been shortlisted for C in 2010.

  The shortlisted authors each receive £2,500 and a specially bound edition of their book. The winner will receive a further cheque for £50,000.
  Australian author Richard Flanagan won last year's prize for his wartime novel The Narrow Road to the Deep North.
