This book is memoir about Agnes and her best friend, Mary Lou. The diamonds belong to Agnes' celebrated grandmother, Harriet Bell Anthony. The story is a mix of characters, in place and out of place, in a peaceful town in Indiana in the late 1940's. The problems center on a sensitive, imaginative twelve-year-old girl who is caught in the inevitable struggle to understand and accept feelings, frustrations and loyalties. The conflicts intensify with the visit of a legentary grandmother in her diamond-heel shoes.
"Later, before they fell asleep, they swore everlasting friendship until the day they died and afterward in heaven."
Diamonds are definitely secondary.
