President Reagan’s daughter’s personal farewell to her father In The Long Goodbye , Patti Davis describes losing her father to Alzheimer’s disease, saying goodbye in stages, helpless against the onslaught of a disease that steals what is most precious—a person’s memory. “Alzheimer’s,” she writes, “snips away at the threads, a slow unraveling, a steady retreat; as a witness all you can do is watch, cry, and whisper a soft stream of goodbyes.” She writes of needing to be reunited at forty-two with her mother, of regaining what they had spent decades demolishing. A truce was necessary to bring together a splintered family, a few weeks before her father released his letter telling the country and the world of his illness. The author delves into her memories to touch her father again, to hear his voice, to keep alive the years she had with him. Moving and honest, an illuminating portrait of grief, of a great man, a disease, and a woman and her father.
