My rating: 3 of 5 stars
Wow! This book got some seriously mixed reviews. I personally liked it, thought I did have some trouble with the Clary/Jace thing while I thought they were related, I'd already read the summary of "City of Lost Angels" so I knew it got resolved.
Jace and Alec, though parabatti, don't seem that connected at all. This would have to be one of my biggest complaints about the book. They are supposed to be closer than brothers, yet they are both always running off doing their own thing. By contrast, I loved the loyalty we see in Clary and Simon. Now they more clearly define what I imagined a "parabotic" relationship to be. They finish out the book clearly and completely interested in others, but their friendship remains steadfast despite the fact that she is a shadowhunter and he is a vampire.
Isbelle grows some throughout this book. She keeps much of her pettiness, but still manages to become a deeper character. I liked that.
The Jace and Sebastian twist is very cool. As is the whole conveluted thing with demon and angel blood.
Clary and Lucian's ability to bring everyone together for the final battles is great. I could feel the tension in the meeting hall as she spoke and they debated and then the excitement as the rune was passed around and applied. AWESOME!
Overall, I think fans of the series will like this book. It brings so much to resolution because it was supposed to be the end of the series, yet it clearly leaves are characters ripe for another story. I for one, am glad Clare continued.
