This is a remarkable book. And, beyond remarkable, it's a good book.

I had a big review all written up full of glowing praise for marvelous world-building, and of admiration of the twisty-turny plotting and intricate scene-setting, and of deep satisfaction with the sheer, frustrating humanity of the protagonist -- but as I know the author, it seemed more than a bit over the top, even if all of it was sincerely felt.

So all I can say is that this is a deeply-crafted urban (or perhaps rural) fantasy that will carry you, like its protagonist, on a white water ride of discovery and drama and horror and hope. It was well worth reading, and will be well worth rereading multiple times in the future.
