The Stone Angel Margaret Laurence

Hagar Shipley, a proud and irascible nonagenarian, retreats in the face of her approaching death and the bitter squabbling of her son and his wife to reflect on her past - her childhood marriage to tough-talking Bram Shipley, her two sons, the harshness of farm life on the prairie, her own failures and the failures and betrayals of others. A bloody minded and independent woman to the end, she embarks on a final wild escapade.
