You could try Graceling by Kristen Cashore.
Here's a description (I hand typed it because I couldn't find it online, so any typo's are mine. Without further ado, the description:
His eyes. Kasta had never seen such eyes. One was silver and the other, gold. They glowed in his sun-darkened face, uneven, and strange. She was surprised that they hadn’t shown in the darkness of their first meeting. They didn’t seem human…
Then he raised his eyebrows a hair, and his mouth shifted into the hint of a smirk. He nodded at her, just barely, and it released her from her spell. Cocky, she thought. Cocky and arrogant, this one, and that was all there was to make of him. Whatever game he was playing, if he expected her to join he would be disappointed.
In a world where people born with an extreme skill --- called a grace --- are feared and exploited, Kasta carries the burden of a grace that even she despises: the grace of killing. She lives under the command of her uncle Randa, King of the Middluns, and is expected to execute his dirty work, punishing and torturing anyone who displeases him. Until one day, when she rebels.

You should try Delirium by Lauren Oliver:
They say that the cure for Love will make me happy and safe forever. And I’ve always believed them. Until now. Now everything has changed. Now, I’d rather be infected with love for the tiniest sliver of a second than live a hundred years smothered by a lie.

Try Uglies Series by Scott Westerfield:
Tally Youngblood is about to turn sixteen, and she can't wait for the operation that turns everyone from a repellent ugly into a stunningly attractive pretty and catapults you into a high-tech paradise where your only job is to party. But new friend Shay would rather hoverboard to "the Smoke" and be free. Tally learns about a whole new side of the pretty world and it isn't very pretty. The "Special Circumstances" authority Dr Cable offers Tally the worst choice she can imagine: find her friend and turn her in, or never turn pretty at all. The choice Tally makes changes her world forever.

Or perhaps Unwind, by Neil Shusterman:
The Second Civil War was fought over reproductive rights. The chilling resolution: Life is inviolable from the moment of conception until age thirteen. Between the ages of thirteen and eighteen, however, parents can have their child "unwound," whereby all of the child's organs are transplanted into different donors, so life doesn't technically end. Connor is too difficult for his parents to control. Risa, a ward of the state is not enough to be kept alive. And Lev is a tithe, a child conceived and raised to be unwound. Together, they may have a chance to escape and to survive

I haven't read Enclave by Ann Aguirre yet, but I hear it's good:
In Deuce’s world, people earn the right to a name only if they survive their first fifteen years. By that point, each unnamed ‘brat’ has trained into one of three groups–Breeders, Builders, or Hunters, identifiable by the number of scars they bear on their arms. Deuce has wanted to be a Huntress for as long as she can remember. (full description here
