I'm a huge fan of Uglies, and decided to pick up some of Scott Westerfeld's other work.
Unfortunately, I was quite disappointed. The world building was great, but something about the actions of the characters did not quite ring true. I came to the conclusion that Westerfeld is simply better at YA fiction than when writing for adults. Mostly, the romance simply...did not work.
On the other hand, the way he draws you into the society itself did. It's still worth a read and would probably have seemed to be a better duology if I did not know Westerfeld could write a lot better. Also...it doesn't end. It stops. Is there going to be a third volume, maybe? I sort of hope so.
