** spoiler alert ** 
 5/5 
 I can't even begin to put in words how much I love this book (and the series in general). I mean, Neal Shusterman has become one of my all-time favourite authors. 
 The plot and the characters... Each has their own distinct tone so you can tell who is narrating at the moment. The characters just continue to grow from Unwind and I can't wait to see how they will continue to develop. 
 Connor having to deal with being a leader and dealing with his rewound arm and trying to think for others instead of how he only thought of himself in the first book. 
 AND RISA. MY POOR RISA. I can't even begin to imagine how hard it was keep composure and when she broke down after the first interview? Oh my poor feels. But she is such a strong character and she is one of my favourite female characters. 
 And then here comes Lev. Damn that boy has grown and he's experiencing his first real interaction with a girl. I just loved seeing his relationship with Miracolina and how she kind of gave him the redemption he needed. 
 AND I DIDN'T THINK I'D LOVE CAM AS MUCH AS I CAME TO. He has found himself with the help of loving Risa and ugh. Enough said. 
 And the plot thickens. Oh, does the plot thickens. THE DEATHS IN THIS BOOK THOUGH. My little heart was breaking into tinier and tinier pieces each time. Like Trace? I just couldn't do it. The slaughter of all those storked kids in the crash. The amount of times I actually felt squeamish and wanted to cry and felt so scared that it is entirely possible that humanity could move towards that route. 
 I could go on and on with this book, but I applaud Neal Shusterman for creating a sequel that was as good, if not better, as the first book.
