Very good, diverting read. I'm impressed at Ms. Saintcrow's alternate Britain, and how fully she immerses the reader therein. The plot is strong with the tension ratcheted up all the way to the end. Her characters are all memorable, though Ms. Bannon is a bit of a Mary Sue, with magical resources that seem to get more limitless are the book progresses, but her reliance on regular recharges of magic at "tideturn" mitigates this somewhat. Her male hero, Clare, thankfully has his own POV and is not just an extension of Saintcrow's heroine. In fact, all her characters seem fully realized, with one exception(sorry - spoilers) All in all a good read, highly recommended.
