Uglies
by Scott Westerfeld
Three hundred years in the future, After the operation, new Pretties cross the river that divides the city and lead a new life with no responsibilities or obligations. There are two other operations available, one to transform Pretties into “Middle-Pretties” (adults with a job), and another to transform Middle-Pretties into "Crumblies".
Former cities have decayed after bacteria infected the world's petroleum, making it unstable. The old society, so dependent on oil, fell apart when cars and oil fields exploded and food could no longer be transported. People who lived before this catastrophe are called "Rusties."
Tally Youngblood is almost sixteen. Like every other Ugly, she awaits the operation with great anticipation. Her best friend, Peris, has already had the operation and, motivated by her desire to see him, Tally sneaks across the river to New Pretty Town. There she meets Shay, another Ugly. They become friends and Shay teaches Tally how to ride a hoverboard. Shay also mentions rebelling against the operation. At first, Tally ignores the idea, but is forced to deal with it when Shay runs away a few days before their shared sixteenth birthday, leaving behind cryptic directions to her destination, a “renegade settlement” called the Smoke, where city runaways go to escape the operation.
On the day of Tally's operation, she is taken to Special Circumstances, a division that is likened to “gremlins” and, “[blamed] when anything weird happens." is the head of Special Circumstances. She gives Tally an ultimatum to either help locate Shay and the Smoke, or never become a pretty. Tally cooperates and Dr. Cable gives her a hoverboard and all the needed supplies to survive in the wild, along with a heart locket that contains a tracking device. Once activated, it will show the location of the Smoke to Special Circumstances. Following Shay's clues, Tally sets off to find her friend.
When Tally arrives at the Smoke, she finds Shay, her friend David and an entire community of runaway Uglies. She is reluctant to activate the pendant and it eventually becomes clear that David is in love with her. David takes her to meet his parents, Maddy and Az, who are the original runaways from the city. They explain how the operation does more than “cosmetic nipping and tucking.” It also causes lesions in the brain to make the people placid, or “pretty-minded.” Horrified, Tally decides to keep the Smoke secret and throws the locket into a fire to destroy it. However, the flames' heat causes the tracker to activate, giving away the Smoke's location.
The following morning, Special Circumstances arrives at the camp and Tally makes an effort to escape. She does not succeed and is caught and taken to a rabbit pen, where other caught Smokies are kept, tied up. Eye scans are taken of all the captured Smokies, identifying from which city they fled. Tally is then taken to Dr. Cable, who explains how they found the Smoke. Because of how long it took to activate the pendant, Dr. Cable suspects that Tally betrayed her but activated it by accident. Dr. Cable tests Tally by ordering her to retrieve the locket, which should be intact. Tally escapes on a hoverboard. After a long and stressful chase, she manages to hide in a cave where they cannot track her heat signature. There she finds David also hiding and together, they begin to plan a rescue.
Tally and David go back to his house, where they find evidence that Special Circumstances took Maddy and Az. David leads Tally to a secret stash of survival equipment After meeting Dr. Cable, David knocks her out and takes her work tablet, which contains all the necessary information to reverse the brain lesions created by the Pretty operation. Tally and David then free all the Smokies held in the complex. As they escape the complex, Maddy tells David that his father, Az, is dead.
Once everyone is safe, Maddy begins working on a cure using Dr. Cable's tablet.
