Enhanced descriptions from Syndetics:

'A beautifully written coming-of-age debut, dreamy and funny ... flawless ' Independent

'Khong is a magician... Brilliant ' Lauren Groff , author of Fates and Furies

'Khong's first novel sneaks up on you - just like life, illness and heartbreak. And love. A million small, human and often deeply funny details gather force to tell a tale that is ultimately, incredibly poignant' Miranda July , author of The First Bad Man

Ruth is thirty 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.
