Other Times 

At the start of the war in 1939 James Bevan is a junior officer approaching middle-age, attached to a small anti-aircraft unit on the south coast.
Abandoned by his wife, the soldiers he command are his family: Bairnsfather, whose sexual encounters with his girl friend Muriel take place in an air-raid shelter; Cartwright, trying to keep two women on his gunner»s pay of a shilling a day; Hignet, cosily educating himself in the orderly room. It is a rude awakening when they are called upon for the real war.
Hugely absorbing, rich and rewarding, Other Times brims with history and experience, love, sorrow and humour.
