The elderly Claudia Hampton, a best-selling author of popular history, lies alone in a London hospital bed. Memories of her life still glow in her fading consciousness, but she imagines writing a history of the world. Instead, Moon Tiger is her own history, the life of a strong, independent woman, with its often contentious relations with family and friends. At its center — forever frozen in time, the still point of her turning world — is the cruelly truncated affair with Tom, a British tank commander whom Claudia knew as a reporter in Egypt during World War II.
