The best book in the series by far. I loved Cyan! Her back story was just totally cool. I have to say that this series got better and better with each book and this one just topped them all off nicely. My only real peeve with this series is the failure to update readers on the previous main characters in other books. Would it have killed her to add a little snippet with Flint, Steel, Ice, Coal, ect ect? Other than that I loved the book, loved the series and think there must be more because the whole Markus model thing has yet to be resolved. So yay for that. Mabye a lady for Deviant?
