I'm not a big fan of multiple points of view, but I thought this was a perfect example of how it can be essential to telling a story. Each viewpoint, even the journal entries, moved the story forward with necessary information. The voices could have been a little more distinctive, but still, very well done. Also, the author did a good job regarding Lilith and Ms. Tripp.
The romance felt genuine with none of the weepy love stuff. Their strong attraction is clear from the start, and it grows in a realistic way. I also loved the interaction between Reese and Nick, and Nick's reactions to Silla's tears. Very authentic.
That said, I didn't buy the harshness that the other kids showed Silla after the Wendy fiasco. If anything, people would be telling Wendy that she's catching Silla's crazy virus. I also got really irritated with the convenient withholding of information. That makes the tension feel contrived. Though, I am glad that most of it got resolved in a few pages as opposed to half the book. :)
The Reese at the end was over the top for me. Not only was it way too harsh on Silla, it also felt like a contrived way to get Reese where the author wants him to be. I think that could have been handled better.
I really liked the Philip/Josephine thing, though, and what Philip did in order to escape her. It made the plot extra complicated, which I love. Even though we knew there was a connection, it was practically impossible to guess.
Regarding Josephine, though, her motivations weren't clear regarding a number of things. Why did she want the spell book so badly? Why wouldn't she just commit murder right off the bat in order to get what she wants (especially since that seems to be her character)? And, why would she wait so long to retrieve the main ingredient in her precious carmot? It felt like a contrived way to create conflict, because she's clearly smart enough and powerful enough to get what she wants in an easier fashion.
I really enjoyed the beginning of this book, but then all the plot holes (and the weird, zombie animals) brought it down a notch. I still like the characters, so I'll read the next book. But I do hope the plot is tighter. :)
