Wolf Hall, the Booker Prize-winning novel by Hilary Mantel, has been shortlisted for the Costa Book Awards. Mantel's novel, set in Henry VIII's Tudor court, is up against Penelope Lively, Colm Tóibín and the little-known Christopher Nicholson - for The Elephant Keeper - for the Costa novel award. This year's Costa shortlists include two posthumous nominations - for Simon Gray in the biography category and Siobhan Dowd in the children's book shortlist - while veteran broadcaster Clive James is nominated in the poetry category for his reminiscences of his Australian childhood.
