I loved this book! After reading the summary I just had to read it and I was glad that I pre-ordered and had it ready to read when I woke up. 
 I've read other books about aliens and stuff like that but the one that I remembered about was Obsidian (Lux series) but this one was much better. The romance was more believable since it wasn't instalove (view spoiler)[the L'eihr's and especially Aelyx hate the humans and are repulsed by them so it wasn't until the more time they spent together and he they fall in love with each other. And then that kissing scene in his room, hot damn indeed! (hide spoiler)] and there was no love triangle (view spoiler)[I mean sure Cara had a boyfriend but then they broke up because of his hatred for the L'eihr's and then he hooked up with her ex-best friend but that's too complicated to go into without ruining some important parts of the story (hide spoiler)] but that one is sort a little complicated to explain, considering that were some parts near the end where I thought a possible love rival turned up but then the inevitable happened... 
 The book just ended there! In a total cliffhanger! But in a totally good way, not those kind of cliffhangers where the action is barely starting and then bam it just ends and you're left wondering what the hell just happened and cursing the author for just ending it there. No, this book ended in a way that makes you want to read the next book that hasn't even come out and probably won't be out until one more year and so you'll pull your hair out in anticipation on what happens next, especially between all the problems they left behind on Earth. (Don't read too much into that). 
 Some of the things I found annoying were the fact that Aelyx should have just been honest with Cara but then again, him keeping that a secret helped his character development and same thing with her, I liked how much she changed into a better person despite everything that was going on at the same time. Another thing that confused me was the time period. From the way it was described, it sounded like modern 2013/2014 but I wasn't too sure. It certainly wasn't a far in the future dystopian novel but nonetheless, despite the small quirks of mine, I really enjoyed this book and will be impatiently waiting for the next book: Invaded that won't come out until February 2015, that's too far away! Guess I'll read the new books in my series that come out this year! 
 HIghly recommend this book tho, you'll be sorry if you miss it!
