In a place and time unknown, two elderly sisters live in a walled garden, secluded from the outside world. Evelyn and Lily have only ever known 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.

When a nameless boy is found hiding in the boarded house at the center of their isolated grounds, their once-solitary lives are irrevocably disrupted. Who is he? Where did he come from? And most importantly, what does he want?

As suspicions gather and allegiances falter, Evelyn and Lily are forced to confront the dark truths about themselves, the garden, and the world as they've known it.
