After a disastrous first meeting, Morgan, 89, moves in with Dixie, age 79, strictly a business arrangement, both maintain. When a "lost" grandson, bent on vengeance for past wrongs, invades their lives, fear and suspicion threaten to ruin their plans. He becomes a catalyst, eventually bringing the couple the love and pride they'd lost decades before with the loss of their children. Award-winning author Mardo Williams completed the first draft of One Last Dance at age 95. His daughters, honoring their father's wishes, finished the book after his death.
