Quick read as most Young Adult books are. Newberry Award winner and a decent read. Not sure if I will request the second book in the series or not. I'd give it two stars out of 5 because I liked it but didn't love it. The main character, Jonas, was a little flat to me until about the last 25% of the book. But then again, I guess you'd be flat too if no one in the world except for one person had any memories of the past. I would recommend this book for young readers. There was nothing racy in it at all and I'm sure that younger people could relate to Jonas.
