Why do so many series books typically have the second book/middle books be written so poorly. I mean don't get me wrong it wasn't horrible and I still enjoyed it, but in comparison to the first book it wasn't as good. Obviously why I gave the first book 4 stars and this book only got 3 stars. I mean a love triangle? Ugh. (view spoiler)[ Specially it being between Sam, Four, and six (hide spoiler)] 
 This book caught you off guard a lot though. Any time that six and four felt as though they were finally safe. BAM! FIGHT SCENE ! RUN! Sam, six, and four are on the run not only from Mogs now but are also on the FBI's most wanted list! They have to remain extra sneaky, extra safe, and don't let anybody find them. When you have super power legacies though and an alien race stalking you and wanting you dead that's kind of hard. 
 This book has another point of view from Number Seven whose hiding out in Spain. Her cepan, Adeline, though is a major disappointment. I wish that she towards the end had some reasoning behind her actions and could justify herself. Nope. To me if felt as if she had lost hope after their years of searching for someone to open their door. That when someone finally did open their door despite how unjust their actions were toward Marina she ignored it. I guess it shows that not every garde was left on Earth with such great Cepans as John had. Marina though, number seven, never gave up unlike her cepan and it was really inspiring to see her strive to push forward no matter what. 
 Badass characters of this book: Six, nine, and Ella (view spoiler)['s cepan ! (hide spoiler)] They were all so fierce, motivating, and determined ! Even though nine only appeared for a few chapters you can still tell that he's a badass. 
 We find out in this book some of the questions left unanswered. BUT! Then there were more added (of course) (view spoiler)[Who was dead at the bottom of Sam's dad's well? Will we ever save Sam? Why would Sarah betray four like that? How are four and six going to find each other again? (hide spoiler)]
