Freshly dis-engaged from her fiancé, with her life at a crossroads, thirty-year-old Ruth quits her job and goes home to her parents. But their situation is more complicated than she'd realized. Her father, a prominent history professor, is losing his memory. Her mother, like Ruth, is smarting from a betrayal. But as her father's condition intensifies, the comedy in her situation takes hold, gently transforming Ruth's grief. Goodbye, Vitamin is the funny and inescapably moving debut of a wonderfully original literary voice.
