The writing was pretty good, the book was interesting - just like the Uglies series, it draws you in. But I couldn't really relate. (Maybe it has something to do with the fact that I'd get classified as a Laggard... :P) 
 Jen (Main character #2, aka love interest) didn't really feel like an innovator. Or I guess Innovators are technically Early Adapters (They're technically cool)/ Laggards (in the sense that they don't follow trends) who end up getting followed? It hit me the wrong way when Jen and Hunter laughed at some girls for wearing the previous year's fashion - I mean, technically since Jen was an innovator, she didn't really care about fashion trends, right? That's what the book explained "Innovators" as - people who wove their own trends instead of following others - but Jen seemed like a combination of both. 
 Unlike the Uglies series, this book doesn't take place in the future. It could've happened today or next year. The book solidifies the "Cool" hierarchy: Innovators at the top (people who come up with the trends); Trendsetters (people who spread the trends); Early Adapters (people who get the good stuff before everyone else); Consumers (people who buy them after being convinced from watching an ad a thousand times; and Laggards (people who go out of their way to not follow fashion trends). And this is pretty much what everyone in the book is judged by. It's shallow - especially the labeling - but does it have a grain of truth to it? That side of the book made it especially boring for me. 
 There is a mystery-ish concept in this book, in the sense that there are a bunch of mysterious people trying to mess up the pyramid. That was the good part of the book - Hunter and Jen end up doing some pretty crazy things trying to find them. ;) This book was roller coaster interesting, snore-yourself-to-death boring, and and somewhat crazy. While I am interested in finding out what happens next, I'm not particularly enthusiastic.
