Rating: 2.5 
 Before I start, this IS a good book for readers who like science-fiction concepts and a little bit of cute, yet heartbreaking romance to go along with it. *It just wasn't MY type,* but I'd totally recommend it for sci-fi readers. ABSOLUTELY PERFECT FOR READERS WHO LIKED THE5THWAVE(not as good, but a close second) 
 This book is separated into 2 parts - the first one being extremely tedious, the second part much better with a lot more going on and a more suspense throughout. The ending with Tyler was extremely heartbreaking, and probably the only part I really enjoyed reading about. I liked the pace that the book went at(not too slow, not too fast) as well as those watching those little details add up in the story. However, there's something that I don't like about it, but I can't pinpoint one specific thing. The concept was good, the idea was good, but maybe a little bit overused. The characters, I didn't find very well developed, which could be a pretty big reason as to why I didn't like it that much; however, I liked the main character well enough to get through it. I enough *should* like this book, as I can't totally list anything I simply hated about it - maybe I just don't like sci-fi. I may or may not pick up the second book, depending how I feel the next time I'm trying to pick up a book.
