I enjoyed this enormously. There were some surprises and some poor reading on my part (my earlier race comment was wrongish, because of my failure to notice and/or remember the race of characters, but also kind of accurate given later developments - it's complicated). Anyway, nice work with archetypes and fairy tales and a premise that is clearly fantasy, but also very grounded and concrete. There's a large cast and lots of plot. But also really nuanced and generous, kind even. Stephen has always showed an understanding of and sympathy with abused women, so a whole lot of compassion towards the inmates of a women's prison is no surprise. But there is also a lot of anger, some of it directed at people behaving badly and some of it directed at society for creating and exacerbating iniquity. Dickensian.
Good on these two for writing a book that is absolutely entertaining, but more than just entertaining.
Good for many squares, and recommended to those who don't care for horror in general.
