In the late summer of 1913, George Sawle brings his Cambridge friend Cecil Valance, a charismatic young poet, to visit his family home. The weekend will be one of excitements and confusions for everyone, but it is on George's sixteen-year-old sister Daphne that it will have the most lasting impact. As the decades pass, Daphne and those around her endure startling changes in fortune and circumstance and, as reputations rise and fall, the events of that long-ago summer become part of a legendary story.
