Moral Disorder (ISBN 0-7475-8162-2) is a collection of connected short stories by Margaret Atwood.

All the short stories have the same female main character at different times of her life, except the last one, which is an autobiographical tale.

Remembering a vacation to Glanum, she imagines them as ancient Romans, discussing over breakfast the bad news about the Barbarian invasions.

The girl struggles to understand what her mother is experiencing, and resents the lack of household contribution throughout the pregnancy.

The young girl works diligently to complete all of the household chores, as well as knitting the baby a layette.

In the present, the main character and her sister talk about the past while driving to visit their mother, whose health is failing.

When the older sister was thirteen, the baby being two, she made a Halloween costume of the Headless Horseman.

Bill, whose strength is algebra and exact sciences, can't understand the poem.

Even when the sexual revolution happens and behavior like hers becomes common, she feels different because she has a seriousness that others don't show.

But she often dreams of being in an apartment similar to the one she had in Vancouver and of knowing that a child is locked away dying in one of the rooms.

She is a free-lance editor and gets a job helping an author, Oona, write a self-help book for women.

In a moment of confidence, Oona tells Nell that her marriage with Tig is in crisis and they stay together only for the benefit of their two sons.

When the lamb grows up, it doesn't adapt to living with the other sheep and becomes aggressive against Tig out of jealousy for Nell.

One night the white mare escapes from the barns, runs into the street, and is killed by a car; Nell feels guilty.

In an outlook into the future, the reader learns that Lizzie's crises eventually stop, and that she gets married, and that Nell and Tig move back to the city.

Their real-estate agent, Lillie, is an elderly lady, a survivor of a German concentration camp.

Oona, meanwhile, has become hostile and accuses Tig of being rich and hiding his money to avoid paying her alimony.

Nell, using a small inheritance, buys a house and allows Oona to live there for a nominal rent to make things easier for all of them.

Nell's mother reads him a book about the doomed Labrador exploration mission of Hubbard and Wallace.

Throughout this, the author attempts to relive the memories that her mother had experienced, however her fragile condition (being blind and one ear deaf) means she does not recall these events.
