Uglies by Scott Westerfield 

Part adventure, part warning: Scott Westerfeld’s Uglies is the first in a trilogy of books set in a world in which everyone has an operation when they turn sixteen, making them supermodel beautiful. Big eyes, full lips, no one fat or skinny. Tally Youngblood will soon turn sixteen, the age she's been waiting for her entire life, to be transformed from an Ugly into a Pretty. As well as beauty, life as a Pretty seems to revolve around having a good time. What could possibly be wrong with that? But not everybody wants to have the operation. Sometimes, they run away, to a community in the forest, the Rusty Ruins, a place where “Uglies” go to escape “turning”. Tally’s views change when she is forced by the State to infiltrate this bunch of radical teens. What she discovers in the Ruins reveals that there is nothing 'pretty' about the transformations...

Just in Case by Meg Rossof 

Meg Rossof’s Just In Case is a different tale of reinvention, darkly comic but no less sinister. What if Fate were out to get you? The day David Case saves his brother's life, his whole world changes. Suddenly, every moment is fizzing with significance, full of 'what if?s'. He must hide, become an entirely new person to escape Fate... if he can. This is a boy in search of a makeover to save his life. Will changing his name, befriending an astrophysicist and gaining an imaginary pet be enough? Bewildered and obsessive, he'll try anything to survive.
