Alright, so probably like everyone else on this planet I decided to read this book after watching the tv show (which yes I know isn't my usual order of things and yeah sure the show has problems but really it's fab and I love it). Moral of the story: I'm so glad I watched the show first. 
 Firstly, I don't think the two are comparable in end products so let's throw that care out the window. I just wanna say I'm glad I had already seen the show because it at least gave me some characterization to apply to the novel's characters. While that sounds like I'm not being fair or had some show bias, I found the lead characters all to have personalities that fell flat. Only the characters who crossed over into the show held some appeal and that was largely cause I was projecting their tv personality over top so, not great. Overall I found the characters to be hardly developed, shallow, unbelievable, and constantly feeling inactive in their own story. 
 Now I don't want to spoil the plot for you, but who am I kidding? There's barely any plot to this novel. At least not one that doesn't concern whose kissing who over the fact that WE ARE LIVING ON AN ESSENTIALLY ALIEN PLANET AND ARE NOT PREPARED FOR THIS. Now don't get me wrong, I love a good romance in any story; zombie comedy? Give me a romance! Sci-fi horror? The scientists are in love! Whatever, I love me a good romance. Unfortunately the central romance very quickly became a doomed love triangle and the other was the only dimension explored of Glass. 
 This book has an awesome premise: put 100 juvenile delinquents on post war earth and see if they can help the survival of mankind. It in no one delivers on that. Granted the first in a series has to lay a lot of groundwork, I don't feel as though this one successfully provided a more than vague back story told largely through flashbacks that mostly acted to expand upon the romances of the novel. 
 Overall, I felt like it had promise, but was unable to deliver. It had no central plot it seemed, but it didn't instead expand its characters. Though I can't fault the book too much since it did bring about the show, which while it does its own problems, definitely delivers.
