In this splendid collection of short stories, Margaret Atwood maps the human motivation we scarcely know we have in a startlingly original voice, full of a rare intensity and exceptional intelligence. With brilliant flashes of fantasy, humour and unexpected violence, these stories reveal the complexities of human relationships and bring to life characters that evoke laughter, compassion, terror and recognition.

Marriage a la mode, Marian discovers, is something she literally can't stomach.

Margaret Atwood is acknowledged as one of the foremost writers of our time. In Moral Disorder, she has created a series of interconnected stories that trace the course of a life and also the lives intertwined with it, those of parents, of siblings, of children, of friends, of enemies, of teachers, and even of animals. As in a photograph album, time is measured in sharp, clearly observed moments.
