2nd book read lately, what do you think about polygamy?

Sister Wife by Shelley Hrdlitschka is a book that delves into a belief that it is okay to have multiple wives.  Nanette longs to become a sister wife, after all, it is essential to her salvation.  But her older sister Celeste, is not too fond of the idea of being told who she can marry, nor marry someone the same age as her father.  Celeste is only 15, but the oldest and the first to wed.  Jon, a boy Celeste's age, returns Celeste's affections.  But when Jon decides to leave the community, Celeste must decide if she is strong enough to go with him and leave behind everything she has ever known.
    Everyone at some point in their life questions what they believe. How would you feel if you had been raised in this type of religious family?
