This review can also be found hereI should probably start off by saying that I had my doubts about this book. I tend to dislike books everyone raves about and the hype surrounding this book (and the entire series thus far) has been insane. The hype almost scared me off from reading this and I'm actually really glad that I picked it up because I absolutely loved it.It was nice to see a book about aliens in YA instead of the usual vampires/werewolves/faeries which make up the stories for a lot of the genre. Really how many alien young adult books are out there? I can't think of many. And the fact that there were good aliens and bad aliens just made the story even better.I loved the plot. Also the story behind the aliens was extremely well thought out and didn't sound ridiculous and was completely original. I loved the fact that different aliens had different powers and no two had the same level of power. Yet even with this they all blended into human society quite well.I loved Katy. She was obsessed with books, had a book review blog and didn't put up with any of Daemon's crap. Because trust me there was a ton of crap from him. That boy seriously got on my nerves in the beginning, to the point where I wanted to smack him. He eventually grew on me when the other, nicer side of him made appearances.When I finished this book I went out and ordered Onyx, the second book in the series. I can't wait to start it and I hope this series just gets better and better.
