What an amazing book! I was surprisingly glued to the pages of this book and I just couldn't stop reading. This book, and this series really, is what an awesome paranormal series should be like. I haven't read too many books about wolves, but of those I have read, none really resonated with me like this series. It also helps when each book is better than the last, which is definitely the case with this series. There was so much suspense and action scattered throughout the book and the plot moved lightening fast without rushing. Things were more intense and bigger than the characters originally thought and all of the truths behind the on-going conspiracies finally come to light. 
 Something about Kyle and Mac's relationship totally made me swoon. I loved it. They were still so hesitant and fragile, it was sweet watching them explore their feelings. I also loved how protective they were of each other. They faced a lot of danger in this book and my heart stopped so many times during those scenes, hoping they'd make it out okay and end up safely in each other arms. I thought they balanced each other out very nicely and I also liked them as individuals. Kyle has that protective quality I love so much and Mac is fiercely loyal to her friends. 
 I have to say that I also really liked Jason. Even bigger than the romance element, I really appreciated the friendship element. Mac, Kyle, Jason, and Amy have all been friends for so long and even though there's tension, they all love each other so much and I respected the hell out of them for being so protective and caring for one another. 
 Willowgrove throws you for plenty of loops, let me tell you. The twists and turns. The lies and betrayals. The deaths! Ugh, quite a few of them broke my heart. And I loved every minute of it. It's not often that I can't put a book down long enough to even go to the bathroom. I swear, I didn't want to let this book go. 
 If you haven't given this series a try yet, then you definitely need to add it to the list. If you're already a fan of the series, then you will love how it all goes down in this last book. I haven't read a lot of good YA paranormal books recently, so it was definitely refreshing to finally read an amazing one. This series had a good balance between being plot-driven and character-driven, and since both elements were done so well, it made for a very impressive read.
