Uglies by Scott Westerfeld
"Tally Youngblood lives in a futuristic society that acculturates its citizens to believe that they are ugly until age 16 when they'll undergo an operation that will change them into pleasure-seeking "pretties." Anticipating this happy transformation, Tally meets Shay, another female ugly, who shares her enjoyment of hoverboarding and risky pranks. But Shay also disdains the false values and programmed conformity of the society and urges Tally to defect with her to the Smoke, a distant settlement of simple-living conscientious objectors. Tally declines, yet when Shay is found missing by the authorities, Tally is coerced by the cruel Dr. Cable to find her and her compatriots–or remain forever "ugly." Tally's adventuresome spirit helps her locate Shay and the Smoke. It also attracts the eye of David, the aptly named youthful rebel leader to whose attentions Tally warms. However, she knows she is living a lie, for she is a spy who wears an eye-activated locator pendant that threatens to blow the rebels' cover. Ethical concerns will provide a good source of discussion as honesty, justice, and free will are all oppressed in this well-conceived dystopia."
