Colm Tóibín: House of Names

On the eve of a great battle, a father commands the death of his daughter to save his army. Three years later, he returns home and his murderous action has set the entire family —- mother, brother, sister - — on a path of intimate violence. As his wife seeks her revenge, the remaining siblings must find a way to right the wrongs of the past even if it means committing themselves to a terrible, barbarous act.
