In A Parliament of Crows, the three Mortlow sisters are prominent American educators of the nineteenth century, considered authorities in teaching social graces to young women. They also pursue a career of fraud and murder. Their loyalty to one another and their need to keep their secrets is a bond that tightens with each crime, forcing them closer together and isolating them from the outside world. Their ever tightening triangle suffers from madness, religious zealotry and a sense of duty warped by trauma they experienced as teenagers in Georgia during Sherman's March to the Sea. As their crimes come back to haunt them and a long history of resentments toward each other boils to the surface, their bond of loyalty begins to fray. Will duty to family hold or will they turn on each other like ravening crows?
