What an odd little book. Essentially a psychological analysis of how one person (in this case the obdurate matriarch of a clan) can inflict emotional damage across generations. The titular Great Granny is stuck in the "correctness" of her own Victorian youth. Her daughter is driven mad and talks to the fairies. Her granddaughter parties all night, smokes all day, and parties obsessively. She also constantly attempts suicide. Deceptively concise, this one is a sleeper.
