OUT OF HIDING. INTO DANGER.
 
Luke Garner is an illegal third child. All his life has been spent in hiding. Now, for the first time, Luke is living among others. He has assumed a deceased boy's identity and is attending Hendricks School for Boys, a windowless building with cruel classmates and oblivious teachers. Luke knows he has to blend in, but he lives in constant fear that his behavior will betray him.

Among the Hidden by Margaret Peterson Haddix

Luke has never been to school. He's never had a birthday party, or gone to a friend's house for an overnight. In fact, Luke has never had a friend. 

Luke is one of the shadow children, a third child forbidden by the Population Police. He's lived his entire life in hiding, and now, with a new housing development replacing the woods next to his family's farm, he is no longer even allowed to go outside.

Then, one day Luke sees a girl's face in the window of a house where he knows two other children already live. Finally, he's met a shadow child like himself. Jen is willing to risk everything to come out of the shadows -- does Luke dare to become involved in her dangerous plan? Can he afford not to?

Extras by Scott Westerfeld

Fame

It's a few years after rebel Tally Youngblood took down the uglies/pretties/specials regime. Without those strict roles and rules, the world is in a complete cultural renaissance. "Tech-heads" flaunt their latest gadgets, "kickers" spread gossip and trends, and "surge monkeys" are hooked on extreme plastic surgery. And it's all monitored on a bazillion different cameras. The world is like a gigantic game of American Idol.

Whoever is getting the most buzz gets the most votes. Popularity rules.

As if being fifteen doesn't suck enough, Aya Fuse's rank of 451,369 is so low, she's a total nobody. An extra. But Aya doesn't care; she just wants to lie low with her drone, Moggle. And maybe kick a good story for herself.

Then Aya meets a clique of girls who pull crazy tricks, yet are deeply secretive of it. Aya wants desperately to kick their story, to show everyone how intensely cool the Sly Girls are. But doing so would propel her out of extra-land and into the world of fame, celebrity...and extreme danger. A world she's not prepared for.

Specials by Scott Westerfeld

"Special Circumstances":

The words have sent chills down Tally's spine since her days as a repellent, rebellious ugly. Back then Specials were a sinister rumor — frighteningly beautiful, dangerously strong, breathtakingly fast. Ordinary pretties might live their whole lives without meeting a Special. But Tally's never been ordinary.

And now she's been turned into one of them: a superamped fighting machine, engineered to keep the uglies down and the pretties stupid.

The strength, the speed, and the clarity and focus of her thinking feel better than anything Tally can remember. Most of the time. One tiny corner of her heart still remembers something more.

Still, it's easy to tune that out — until Tally's offered a chance to stamp out the rebels of the New Smoke permanently. It all comes down to one last choice: listen to that tiny, faint heartbeat, or carry out the mission she's programmed to complete. Either way, Tally's world will never be the same.

Pretties by Scott Westerfeld

Gorgeous. Popular. Perfect. Perfectly wrong.

Tally has finally become pretty. Now her looks are beyond perfect, her clothes are awesome, her boyfriend is totally hot, and she's completely popular. It's everything she's ever wanted.

But beneath all the fun -- the nonstop parties, the high-tech luxury, the total freedom -- is a nagging sense that something's wrong. Something important. Then a message from Tally's ugly past arrives. Reading it, Tally remembers what's wrong with pretty life, and the fun stops cold.

Now she has to choose between fighting to forget what she knows and fighting for her life -- because the authorities don't intend to let anyone with this information survive.

Uglies by Scott Westerfeld

Tally is about to turn sixteen, and she can't wait. Not for her license -- for turning pretty. In Tally's world, your sixteenth birthday brings an operation that turns you from a repellent ugly into a stunningly attractive pretty and catapults you into a high-tech paradise where your only job is to have a really great time. In just a few weeks Tally will be there.

But Tally's new friend Shay isn't sure she wants to be pretty. She'd rather risk life on the outside. When Shay runs away, Tally learns about a whole new side of the pretty world -- and it isn't very pretty. The authorities offer 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.

The Red Pyramid by Rick Riordan

Since their mother's death, Carter and Sadie have become near strangers. While Sadie has lived with her grandparents in London, her brother has traveled the world with their father, the brilliant Egyptologist, Dr. Julius Kane.

One night, Dr. Kane brings the siblings together for a "research experiment" at the British Museum, where he hopes to set things right for his family. Instead, he unleashes the Egyptian god Set, who banishes him to oblivion and forces the children to flee for their lives.

Soon, Sadie and Carter discover that the gods of Egypt are waking, and the worst of them —Set— has his sights on the Kanes. To stop him, the siblings embark on a dangerous journey across the globe - a quest that brings them ever closer to the truth about their family and their links to a secret order that has existed since the time of the pharaohs.
