Twins Jeanie and Julius have always been different from other people. At 51 years old, they still live with their mother, Dot, in rural isolation and poverty. Inside the walls of their old cottage they make music, and in the garden they grow (and sometimes kill) everything they need for sustenance. But when Dot dies suddenly, threats to their livelihood start raining down. Jeanie and Julius would do anything to preserve their small sanctuary against the perils of the outside world, even as their mother's secrets begin to unravel, putting everything they thought they knew about their lives at stake.
