I really enjoyed this book. The Study series was so fun to read and I can tell that this spin off series is going to be just as good or even better. I love the world that Maria V Snyder has created. There are some really great new characters in this book and it was exciting when a character from the Study books entered the story. I can't wait to read the next book. The ending of this one left you with some unanswered questions andI think that it will lead Opal into some exciting new adventure. I hope that story keeps her in Ixia.
