Memory board

For forty years David Crown has kept his twin sister Diana a secret. Until his wife's death, not even his children--Diana's nieces and nephews--have known about Diana and her lifetime companion Constance. But now David seeks to bridge over those years and recapture the closeness of childhood, to become part of Diana's life, to have her be a major part of his. For the independent, irascible Diana, the overtures from her brother are an unwelcome intrusion. Retired from her medical practice, she spends her days fully occupied with Constance, for whom memory is increasingly a sometime thing. David, growing ever more fond of the enchanting Constance, struggles to win her trust... And Diana is inexorably drawn into the event and drama of David's family life.
