Lia no longer believes in before. Six months after the crash that killed her, six months after being reborn, Lia has finally accepted her new reality. She is a machine, a mech, and she belongs with her own kind. It's a wild, carefree life, without rules and without fear. Because there's nothing to fear when you have nothing left to lose.

One year ago Lia Kahn died. A few days later she woke up. She had a new body: mechanical, unfeeling, inhuman. She had a new family: mechs like her, who didn’t judge her for what she could no longer be. She had a new life, one that would last forever. At least, it was supposed to....

In the second book of the Uglies series, Tally's Pretty. And everything's changed. The new, Pretty Tally is totally happy right where she is. She doesn't think she needs any kind of cure at all. When someone from her Ugly life shows up with a message, Tally has a hard time listening. Did she really promise to give all this up? Is she bound by a promise she made when she was a different person?

Extras, the final book in the Uglies series, is set a couple of years after the "mind-rain", a few earth-shattering months in which the whole world woke up. The cure has spread from city to city, and the pretty regime that kept humanity in a state of bubbleheadedness has ended. Boundless human creativity, new technologies, and old dangers have been unleashed upon the world.

Tally lives in a world where your 16th birthday brings aesthetic perfection: an operation that erases all your flaws, transforming you from an "Ugly" into a "Pretty". She is on the eve of this important event and cannot wait for her life to change. As well as guaranteeing supermodel looks, life as a Pretty seems to revolve around having a good time. But then she meets Shay, who is also 15 - but with a very different outlook on life.
