Okay, so this book isn't perfect. The war it depicts is simply logically unsustainable, particularly on the planet it takes place on. But really, such points are quibbles, for this is an outstanding work of science fiction. Hurley's world building is outstanding, her characterization if her leading cast is powerful, her narrative is sparking.Don't think that this is an easy book to get into, it really isn't. Like Mieville's Perdido Street Station, it confronts the reader rather than welcomes you in. It is hugely rewarding to the careful reader who allows their mind to inhabit the world of Nyxnyssa and her band of violent murderers. Outstanding.
