Description:

Receiving a manuscript and request for feedback from her vengeful ex-husband of fifteen years, Susan Morrow is drawn into the life of the story's fictional character and confronts a devastating parallel darkness from her own past.

Austin Wright's novel is a disturbing and dazzling work: it describes a special reading experience, combines the suggestiveness of a thriller and the depth of a psychological novel. He talks about fear and regret, revenge and maturation, marriage and failure.
