Hello, ageing parents. Hello, dementia. Goodbye, vitamin.... Ruth is 30, and her life is falling apart: she and her fiancé are moving house, but he's moving out to live with another woman; her career is going nowhere; and then she learns that her father, a history professor beloved by his students, has Alzheimer's. At Christmas her mother begs her to stay on and help. For a year. Goodbye, Vitamin is the wry, beautifully observed story of a woman at a crossroads, as Ruth and her friends attempt to shore up her father's career; she and her mother obsess over the ambiguous health benefits - in the absence of a cure - of dried jellyfish supplements and vitamin pills; and they all try to forge a new relationship with the brilliant, childlike, irascible man her father has become. 1.
