I really enjoyed this one. Etta of the title is Etta Place, the reputed girlfriend/wife of the Sundance Kid. Very little is known of this young woman's life before or after her association with the outlaws of the Hole in the Wall Gang. Koplan has written an entertaining tale of who Etta may have been - based on speculation and news stories of the time. He tells the story with alternating chapters of narrative, diary entries, letters, and news stories. All these help ground the novel in the time depicted. Koplan stays true to history where possible, but does have his Etta rub elbows with some of the mighty of the time. Recommended to anyone who enjoys a good Western.
