Conversation: Louise Erdrich, Author of 'The Round House'

A woman is attacked, a family is altered forever, the only child, a 13-year-old boy, seeks to solve the mystery surrounding the crime. The dramatic outline of the new novel, "The Round House," is further complicated by its setting on a reservation in North Dakota, where tribal law and ways clash with state and federal jurisdictions. "The Round House" has been nominated for National Book Award.
