** spoiler alert ** 
 When I first decided to read this book, I was sure I'd be reading a story something like a cross between 1999 television series Roswell and the 1999 television series Dark Angel. I was right. I was reminded so much of those shows throughout the entirety of this book. And I loved ever second of it. But it also gave me something different to take in. 
 The hero, Four (John Smith), is fearless and nonchalant and sure of himself. Not exactly what you would expect from an alien hiding on Earth from his enemies. I was surprised by it, but at the same time, it was kind of refreshing. 
 This book captured me early on and I had a hard time stopping to read it every night when it was time to go to sleep. The enemies, the Mogadorians, truly petrified me. The way they were described reminded me of "The Gentlemen" from a Buffy the Vampire episode I had seen in my youth. When the Mogadorians arrived in Paradise, Ohio, I was so scared I was literally holding my breath while reading the school scene. 
 This book is so well depicted and thought out, and just plain fun to read. It was such a wonderful story. 
 Last but not least, the romance aspect. I actually love the romance between Sarah and John. their 'lovy dovy gushiness' doesn't annoy me as much as I would have thought. It feels like he's bound to her in some strong way and I really like that. Of course, there was mention of his chosen other half on Lorien who just so happens to be one of the six aliens left of Earth. Could it be number Six? If so, she truly doesn't seem interested in Four/John in that way. I think she will develop a closeness to Sam. At least I think she should. 
 To say I'm excited for the second book of this series is an understatement. I can't wait for it's release. I'm so devoted and invested into these characters already. I think this is going to be an amazing series!
