Just finished my third read through this series. And it keeps getting better with each read. I'm really excited for the release of 
 at the end of May. 
 This book is a little darker than the previous ones. Kate has to make some life changing decisions in this book and for the majority of the book she is brooding about her decisions and her relationships. It's not a bad "pity-me" brooding. She doesn't let it control her whole life, she still has her work with the order to do and it doesn't get in the way of that, but she does have to take it into consideration because these things will effect everyone around her. Mainly I'm talking about her realtionship with Curran. She was always told not to form relationships because they would make her vunerable and here she's in love. So, do you give up potential happiness to keep him and everyone safe? Or, do you voluntarily sign them up for potential torture and death at the hands of your "ready-to-kill" father? It's definitely something Kate ponders. 
 A lot of changes occur by the end of the book and there are a couple of open story lines that will hopefully be explored in the next book. Overall, however, the book has a nice HEA and it's hopeful and not biting-your-nails waiting to see what happens to the characters. 
 The next book will keep the same major storyline going (Kate and eventual Roland confrontation) but for the majority of the characters they were put into new situations in this book that will be nice to see what direction they are taken. Keeping the story fresh. 
 I absolutely love these characters. This will be a series that I will come back and read time and time again. I love what the authors have created and I hope they continue to do so.
