In a world that is rapidly descending into chaos, Frey and Rafi are twin sisters, but few people know of Frey's existence, because she has been raised to be her sister's body double and lethal bodyguard, while Rafi has been raised to further the family's political power--but when their father sends Frey in her sister's place as collateral in a tricky deal, Col, the son of a rival leader, gets close enough to begin to suspect something, and Frey must...

Assuming her twins identity, Frey works to destroy her father, but when a rebel uprising strands her in a city that comes under attack, Frey must step out of the shadows to find her missing sister and take action against her tyrant father.

After rebel Tally Youngblood brings down the uglies/pretties/specials regime, fame, instead of beauty, becomes the new world order, and fifteen-year-old Aya Fuse embarks on a dangerous plan to boost her popularity ranking.

Don't call them heroes, but these six Californian teens have powers that set them apart. Take Ethan, a.k.a. Scam. He's got a voice inside him that'll say whatever you want to hear, whether it's true or not. Which is handy, except when it isn't -- like when the voice starts gabbing in the middle of a bank robbery. The only people who can help are the other Zeroes, who aren't exactly best friends these days. Enter Nate, a.k.a. Bellwether, the group's...

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,...

In an alternate 1914 Europe, fifteen-year-old Austrian Prince Alek, on the run from the Clanker Powers who are attempting to take over the globe using mechanical machinery, forms an uneasy alliance with Deryn who, disguised as a boy to join the British Air Service, is learning to fly genetically-engineered beasts.

Continues the story of Austrian Prince Alek who, in an alternate 1914 Europe, eludes the Germans by traveling in the Leviathan to Constantinople, where he faces a whole new kind of genetically-engineered warships.

IT'S TIME TO COME OUT OF HIDING Frey has spent her life in a family of deceivers, a stand-in for her sister, manipulated at her father's command. Free from them at last, she is finding her own voice - and using it to question everything her family stood for. Tally was once the most famous rebel in the world. But, for over a decade, she's kept to the shadows, allowing her myth to grow even as she receded. Now she sees that the revolution she led has...

Alek and Deryn encounter obstacles on the last leg of their round-the-world quest to end World War I, reclaim Alek's throne as prince of Austria, and finally fall in love.
