The 19th Wife. David Ebbershoff

An excellent book.  Follows two adjacent stories of a young man who was ejected from the extreme mormons, called the Firsts.  His mother is accused of murdering his father (she is the 19th wife).  It also follows the life of Eliza Anne Young who was the 19th wife of Brigham Young.  Really intersting to learn about the history of the church and the conditions within polygomous marriage.
