In a place and time unknown, two elderly sisters live in a walled garden, secluded from the outside world. For as long as they can remember, Evelyn and Lily have only had each other. What was before the garden, they have forgotten; what lies beyond it, they do not know. Each day is spent in languid service to their home- tending the bees, planting the crops, and dutifully following the instructions of the almanac written by their mother. So, when a nameless boy is found hiding in the boarded house at the centre of this new Eden, the reality of their existence is irrevocably shattered. Who is he? And where did he come from?
