This year the Orange Prize for Fiction is celebrating its 10th year in association with Woman's Hour. To mark the occasion we're inviting you to vote for your favourite winner. Each of the Orange Prize judges will try in turn to persuade you that their winning novel deserves your vote.
Today, co-founder of the Orange Prize for Fiction, Kate Mosse, discusses the merits of Helen Dunmore's 1996 winning novel, A Spell of Winter.
