Anna Wulf is a young novelist with writer's block. Divorced, with a young child, and disillusioned by unsatisfactory relationships, she feels her life is falling apart. Fearing the onset of madness, she records her experiences in four coloured notebooks. The black notebook addresses her problems as a writer; the red her political life; the yellow her relationships and emotions; and the blue becomes a diary of everyday events. But it is the fifth notebook -- the Golden Notebook -- which is the key to her recovery and renaissance.
