Unfortunately I couldn't read this book as fast as I wished because I was in the middle of a move, but trust me when I say that this is the only reason why I had to put it down so many times. The book is so involving that all you wanna do is keep reading!
About the characters, as I wrote in my review for "Nightshade", every one of them is well developed and interesting, but I have to say that in this book sometimes I felt lost about some reactions... A few unexpected events happened and someone seemed not to react as he/she should have... Of course this could it be because there's still lots of mystery around so many things that we can't see everything clearly yet, but I really was expecting a different reaction by someone when something shocking was revealed... And mostly from Calla, as I thought her mind was elsewhere and she was completely astounded.
My big complain would be Ren... I really wanted to read more about him, but since the dynamic of the story I perfectly understand his almost complete absence... I mean, it's justified because we already know different things about Werewolves and Keepers but not so much about Searchers and this second book is all about them, or at least the biggest part. We knew their real place and role in the story and Gosh if it's intriguing! Maybe there were a couple of things predictable, at least for me, but that didn't make them less interesting.
At some point something has broke my heart, but in the end there's that final scene... The one I'm dying to read about! The beginning of "Bloodrose" is preannounced like something amazing and I hope it's just a taste of another great book of a beautiful series!
