True to the young adult genre, there is also a love triangle, but I like Westerfield's take on it. Instead of love being the force that drives Tally, it exists outside the main plot line. It is a secondary plot to a much bigger cause.
Finally, the adult take on this is that it teaches a lesson that most teenagers forget. It is admirable to walk your own way, to be independent, and to never let anyone else think for you. Seeing teenagers lose their individuality on a daily basis inside the walls of a high school has helped me see the value in this novel. After all, we are all Uglies, and the book shows that there is no superior race.
