As I've heard stated a few times in regards to this series, it gets better and better with each book. This statement it very true. Each character has grown so much since the first book that I almost want to go back and re-read the first novel just to see where everyone has come from. There's only one more book left in the series and I think everyone can guess what the big confrontation will be next. This book took a slight detour from dealing with Calvin Malone to dealing with Thunderbirds. While Rachel Vincent has not gone the usual route in her books by introducing vampires and werewolves (not a bad thing) the Thunderbirds (and the one bear shifter) are the only other species we've seen in this world. It's nice that the books don't take the normal lead in this regard. 
 I would say one of the big issues in this outing is that between Faythe, Marc, and Jace. This is the story were events from the previous book are revealed and we get to see what the consequences are. Honestly, I liked the way Rachel Vincent handled the whole situation. I was afraid going into this book that there would be a lot of "I love him, but I love him too" thought going on. Don't get me wrong, there are plenty, but it didn't get annoying for me like it has in previous series where a love triangle pops up. I think it has mainly to do with the men's reactions to the knowledge. They both obviously care, and they are not too happy either, but they both realize the job that needs to be done. They are willing to let Faythe make her own decision. Lets just hope it stays this way in the next book too and does't turn into a "choose me, and let me show you why you should choose me" type of a fight. 
 I really have to give credit to Rachel Vincent for Faythe's alteration throughout the course of this book. In the first novels she was a spoiled brat who didn't want anything to do with the Pride and wanted to be free to make her own choices. She really cared about no one but herself. In these last couple of novels, however, she has grown into a think-before-you-speak type of person and you can really see how she could be a great Alpha one day. This comes through clearly especially in this book where she does have to weigh some choices with the good of the whole Pride or werecats vs. the good of her Pride / family. 
 It will be strange that the story will be ending with the next book, but it feels right, and I'm glad there's a definite end in sight. Sometimes to continue a series on too long ruins the characters / world that was built. I look forward to the last installment, and even after that I believe this will be a series I read over again in the future.
