Here's the deal. This book kept me reading and entertained, but it reminded me more of fanfiction. Which is not an insult. I read fanfiction regularly. However, there are some things I'm willing to go with in fanfiction that become detractors in a novel. 
 1) Characterization- These characters felt kind of bland overall, and very much archetypes. Oh look a girl who is "special" but seems to have not many other discernible qualities. The nice guy who's been around kind of forever. And quirky girl has a crush on. The bad boy who swoops in out of nowhere. Quirky human friends. Random mean girl taunting from the sidelines (Who is the only other human girl apart from Layla we really see. And friend Stacy is approached as oversexed in a way that's more annoying than empowering. So, what this books has to say about teenage girls is a road I'm somewhat afraid to travel down.) 
 These familiar character types are all well and good. Just give me more. Let them be a little more than that. To go with the fanfiction thing, often in fanfiction I am willing to go along with a more basically drawn character because I already have a history with that character. I know who they are. Unfortunately, I don't really get the same feeling here. Needless to say, if I continue the series (and I may very well), I look forward to seeing these characters grow. 
 2) Plot- Just the previous reveals there is not really much too surprising here. Neither do the stakes really feel all that high. 
 3) World creation- This did not feel like a fully flushed out world. It has a hell of a lot of potential, and I was ready to be all in. But I just wasn't. 
 4) Writing style- The prose here was very too the point. I didn't have any worlds crafted before me. The tone was somewhat middle of the road. Some of the internal thoughts of the heroine made me want to smack things. 
 This book was pretty formulaic. And you know what, that can be okay. Comforting even. I enjoyed myself fine. It just felt somewhat like an outline that hadn't been colored all the way in.
