AS Byatt is a writer and recognised as a distinguished critic, contributing regularly to journals and newspapers including the Times Literary Supplement, The Independent and the Sunday Times, as well as to BBC radio and television programmes. A. S. Byatt's first novel, Shadow of a Sun, the story of a young girl growing up in the shadow of a dominant father, was published in 1964 and was followed by The Game (1967), a study of the relationship between two sisters. Her most successful book, Possession: A Romance (1990), won the Booker Prize for Fiction and the Irish Times International Fiction Prize, and continues to enjoy enormous critical and popular success. Part romance, part literary thriller, the story involves two contemporary academics, Roland Michell and Maud Bailey, whose research into the lives of two Victorian poets, Randolph Henry Ash and Christabel LaMotte, reveal inextricably linked destinies, like those of their researchers. The Children's Book (2009), was shortlisted for the 2009 Man Booker Prize for Fiction and won the 2010 James Tait Black Memorial Prize (for fiction). Ragnarok: the End of the Gods was published in 2012.
