I loved this book and tore through it in a day. I really liked the main character Jane McKeene as an action hero with depth, and I liked Kate's development throughout the book, although I'm still iffy on her. The structure with snippets of correspondence between Jane and her mother starting each chapter worked really well. I appreciated the author's attention to historical detail (Reconstruction, creation of white havens in the west, and the industrial schools) when creating this new world. My only complaint was it felt like some reveals went nowhere (Mayor Carr, the tinkerer, electricity), but maybe they'll have more meaning in later novels.
