Falling Angels by Barbara Gowdy
The three Field sisters live in the sanitized suburbs of the fifties and sixties, but their plastic world is askew. They are growing up crazy in a very eccentric, often miserable, sometimes hilarious family. Their home is a war zone ruled by an abusive father - a philandering used-car salesman hooked on booze, guns and discipline. And whenever their mother's coffee mug is empty they hurry to refill it with whiskey, for they know she's living precariously in the wake of the strange unspeakable act she once committed against the family.
These falling angels - tough-talking Lou; sensible, sentimental Norma; chic, naïve Sandy - go through rites of passage each in her own way. They turn to drugs, swinging sixties sex, schmaltzy fantasy - and, repeatedly, to one another. And, even after her death, they turn to their mother, and to the bizarre love they discover their father bore her, a love he must commemorate at Niagara Falls
