At the edge of a woods, on the grounds of a defunct free school, Ava and her brother, Fred, shared a dreamy and seemingly idyllic childhood - a world defined largely by their imaginations and each others presence. Everyone is aware of Freds oddness or vague impairment, but his parents fierce disapproval of labels keeps him free of evaluation or intervention, and constantly at Avas side. Decades later, then, when Ava learns that her brother is being held in a county jail for a shocking crime, she is frantic to piece together what actually happened. A boy is dead. But could Fred really have done what he is accused of? As she is drawn deeper into the details of the crime, Ava becomes obsessed with learning the truth, convinced that she and she alone will be able to reach her brother and explain him and his innocence to the world.
