A Bond-like villain; the last general of the alien Airlia intended in punishing the human race while intended in make a device to ask for reinforcements; a mysterious being looking for ways to uncover the hidden truth of Lisa Duncan past; renegade watchers that don't limit themselves to watch; these are some parts of the book that I liked, which are enriched by the militar expertise of the writer who was a special forces soldier, so the tactics go beyond the limitations of writers that usually only get to imagine the Troy Horse. But what made me love this book was the final, all the things that bugged me, as the contempt the Airlia had in regard of humans, the superiority of Aspasia's Shadow toward the best humanity could do against him, the why the Airlia are in this planet, all those things have a very good answer in just a short statement, which makes it the most shocking.
Somehow I consider this book the last one of the series. Not that the rest are not interesting, they are and a lot as I loved the eighth book "Nosferatu," is that the next books in the series seem to be quite different from the world it portrayed in the beginning. The books after this one show a bit more of the past, answer some additional questions, but they are another world apart from this one.
