Damn, this is a good book. Hard to read, in some ways, because it's the story of two girls and their mother, who fled the (literally) burning temple of their cult, ran as far as the mother could take them, and washed up somewhere in Oklahoma. Because the story is told from the inside - the education of the girls doesn't include reading, for example, so clearly their lives and backgrounds are dramatically different from that of the average reader - the story of the history of the cult, the polygamous family that it constituted, unfolds from their perspective, slowly. Hard to read, because they believe so hard, and that belief is fundamentally corrupted at its very heart, and you know it reading from the outside.
Anyway, damn. Good book. Very good book.
