Our non-fiction list is a veritable cornucopia of delights: top history and military titles from Antony Beevor, Andrew Roberts, Martin Gilbert and Antonia Fraser rub shoulders with giants of science such as Richard Dawkins and Susan Greenfield. An impressive collection of gardening and cookery titles vie for space with philosophy from A.C. Grayling, Thomas Pakenham's stunning 'Trees' series and sports and popular culture titles such as the Manchester United books. We can boast the best in travel writers – with Michael Palin, Robert Twigger, A.A. Gill, Nicholas Crane and Carol Drinkwater; and who can forget our sartorial bestselling guides by Trinny & Susannah?
