This was my second time reading this book, and let me tell you, it was fantastic. Haddix is definitely one of my favorite authors, and I'll just say that I loved this book again and again. This series has been one of the only ones that I never want to put down. And by never, I mean never. The books are short, but oh boy, are they beautiful. This one...I loved this one. 
 Plot: The plot is superb. The plot is lengthy and complex, surprising for a book its size, but don't worry, the book hardly seems very rushed at all. The plot was so much different from any other book today, and in that way it was very fresh. Plus, it isn't just important thing after important thing so that it makes your head spin. Mostly, the book lets you relax for a little bit, so both the reader and the characters can adjust themselves. The plot is a fantastic A+. 
 Characters: The characters were very fleshed out too. We really got to know Luke, and even some of the supporting characters, such as his brothers. And plus, you're bound to like at least ONE character in the bunch. All of the characters have unique personalities and actually seem realistic. Jen is one of my favorites (personally). And speaking of Jen, her family is described to be excellent bribers, and they actually display this trait, apparently. Obviously, since this book is the first in a series, we haven't gotten to know the characters TOO much yet, but we definitely will. Eventually. 
 Writing/Humor/Style: There wasn't much humor in this book, but there is still some. I definitely smiled at Luke's brothers' antics, as well as Jen's. And it makes sense that there isn't much humor, because this is like a dystopian setting here. It's meant to be somber, not humorous. But anyway. 
 I LOVED the pacing. It's a quick pace that makes sure you don't get bored of the book at any moment in its story. And the pacing was perfect for a story like this. The writing was beautiful, too, and definitely suited the situation. The formality of the letters from the Government, Luke's anxiety, it was all grand. 
 Overall, I adored this book the second time around. I'm trying to reread the whole series, so I'm adding Among the Imposters to the top of my to-read list now. 
 5/5.
