Forget everything you ever knew about unicorns. The fluffy, sparkly, friendly “horses” so popular the world over don’t exist. Real unicorns are killers.
Beasts the size of elephants, with cloven hooves that shake the earth, hides impervious to bullets, and horns that contain a deadly poison, unicorns can outrun a sports car and smell a human from a mile away.
And they can only be killed by virgin warriors descended from Alexander the Great. 
Sixteen-year-old Astrid Llewelyn has grown up with her mom Lilith’s tall tales about unicorns and their exalted family heritage, but figures her mom’s crazy. But the scary stories her mom told her about the monsters in her formative years left her with a firm phobia about unicorns, even the cutesy kind popular with young girls.
But when one of the monsters attacks her boyfriend in the woods—thereby ruining any chance of him taking her to prom—Astrid finds herself headed to Rome to train as a unicorn hunter.
“As swift and sure-footed as a killer unicorn, Rampant weaves a vibrant new mythology from venerable threads.”—Scott Westerfeld, bestselling author of the Uglies series

Beasts the size of elephants, with cloven hooves that shake the earth, hides impervious to bullets, and horns that contain a deadly poison, unicorns can outrun a sports car and smell a human from a mile away.
And they can only be killed by virgin warriors descended from Alexander the Great.
Astrid Llewelyn is now a fully trained unicorn hunter, but she can't solve all her problems with just a bow and arrow. Her boyfriend, Giovanni, has decided to leave Rome, the Cloisters is in dire financial straits, her best friend's powers are mysteriously disintegrating, and Astrid can't help but feel that school, home, and her hopes of becoming a scientist are impossible dreams.
So when she's given the opportunity to leave the Cloisters and put her skills to use as part of a scientific quest to discover the Remedy, Astrid leaps at the chance. Finally, she can have exactly what she wants—or can she?
At Gordian headquarters in the French countryside, Astrid begins to question everything she thought she believed: her love for Giovanni, her loyalty to the Cloisters, and—most of all—her duty as a hunter.
Should Astrid be saving the world from killer unicorns, or saving the unicorns from the world?

Rampant (Killer Unicorns, Book 1) (Killer Unicorns, 1)

Fans of Divergent will love Diana Peterfreund’s take on Jane Austen’s Persuasion set in a post-apocalyptic world. In the dystopian future of For Darkness Shows the Stars, a genetic experiment has devastated humanity. In the aftermath, a new class system placed anti-technology Luddites in absolute power over vast estates—and any survivors living there. Elliot North is a dutiful Luddite and a dutiful daughter who runs her father’s estate. When the boy she loved, Kai, a servant, asked her to run away with him four years ago, she refused, although it broke her heart. Now Kai is back. And while Elliot longs for a second chance with her first love, she knows it could mean betraying everything she’s been raised to believe is right. For Darkness Shows the Stars is a breathtaking YA romance about opening your mind to the future and your heart to the one person you know can break it.

For Darkness Shows the Stars (Stars, 1)

Balzer + Bray

Centuries after wars nearly destroyed civilization, the two islands of New Pacifica stand alone, a terraformed paradise where even the Reduction--the devastating brain disorder that sparked the wars--is a distant memory. Yet on the isle of Galatea, an uprising against the ruling aristocrats has turned deadly. The revolutionaries' weapon is a drug that damages their enemies' brains, and the only hope is rescue by a mysterious spy known as the Wild Poppy. On the neighboring island of Albion, no one suspects that the Wild Poppy is actually famously frivolous aristocrat Persis Blake. The teenager uses her shallow, socialite trappings to hide her true purpose: her gossipy flutternotes are encrypted plans, her pampered sea mink is genetically engineered for spying, and her well-publicized new romance with handsome Galatean medic Justen Helo... is her most dangerous mission ever. Though Persis is falling for Justen, she can't risk showing him her true self, especially once she learns he's hiding far more than simply his disenchantment with his country's revolution and his undeniable attraction to the silly socialite he's pretending to love. His darkest secret could plunge both islands into a new dark age, and Persis realizes that when it comes to Justen Helo, she's not only risking her heart, she's risking the world she's sworn to protect. In this thrilling adventure inspired by The Scarlet Pimpernel, Diana Peterfreund creates an exquisitely rendered world where nothing is as it seems and two teens with very different pasts fight for a future only they dare to imagine.
