May is at a crossroads. Although her career as a gardener for the university is flourishing, the rest of her life has narrowed to a parched routine. The missing element, she realises, might be friendship. As May sets off on a journey to visit four neglected friends one-by-one, she holds herself (and them) to humorously high standards, while at home she begins to confront the pain of her past and imagine for herself a different kind of future. May's quest becomes an exploration of the power, and perhaps limits, of modern friendship.
