The 19th Wife: Three-Sentence Book Review

The 19th Wife, by David Ebershoff
Polygamous ("plural marriage") Mormonism, from the nineteenth-century perspective and the twenty-first-century perspective.  I liked the different ways he told the story: chapters from another book, a letter, first-person narration.  But some of it was too slow, so recommended if you have a lot of time and are good at persevering.
