There are many excellent books about Malta at war. Fortress Malta is one of the more recent and it is an enjoyable read. For an RAF fighter pilot's very honest perspective try Dennis Barnham's Malta Spitfire Pilot, originally published as One Man's Window.
The 1952 film, Malta Story, despite some inaccuracies, tells a good story and there are some strong performances from Jack Hawkins, Alec Guinness and Muriel Pavlov. The love interest in the film between the Pavlov and Guinness characters is fictitious but it has many similarities to the true but ulimately tragic (for both) romance between Adrian Warburton, the RAF's most highly decorated recce pilot, and the vivacious English dancer Christina Ratcliffe who became Captain of D Watch and the Assistant Controller in the Lascaris Fighter Control Room at the height of the battle
Tony Spooner's excellent biography, Warburton's War, makes fascinating reading, while Christina's story is one of two retold by Frederick Galea in Women of Malta.
