Richard Yates - Easter Parade
Great first line
"Neither of the Grimes sisters would have a happy life, and looking back it always seemed that the trouble began with their parents' divorce."
That's how it starts and it goes downhill from there.
That is, the unhappiness, not the quality of the novel.
Richard Yates, mostly forgotten today, draws from the deep well of his own unhappinesses to pour forth this painful story.
