Rose and Lissa become enmeshed in forbidden romance, the Academy’s ruthless social scene, and unspeakable nighttime rituals. But they must be careful lest the Strigoi—the world’s fiercest and most dangerous vampires—make Lissa one of them forever.

It’s winter break at St. Vladimir’s, but Rose is feeling anything but festive. A massive Strigoi attack has put the school on high alert, and now the Academy’s crawling with Guardians—including Rose’s hard-hitting mother, Janine Hathaway. And if handto- hand combat with her mom wasn’t bad enough, Rose’s tutor Dimitri has his eye on someone else, her friend Mason’s got a huge crush on her, and Rose keeps getting stuck in Lissa’s head while she’s making out with her boyfriend, Christian! The Strigoi are closing in, and the Academy’s not taking any risks.... This year, St. Vlad’s annual holiday ski trip is mandatory.

But the glittering winter landscape and the posh Idaho resort only create the illusion of safety. When three friends run away in an offensive move against the deadly Strigoi, Rose must join forces with Christian to rescue them. But heroism rarely comes without a price…

He’d rather die than be one of them, and now Rose must abandon her best friend, Lissa—the one she has sworn to protect no matter what—and keep the promise Dimitri begged her to make long ago. But with everything at stake, how can she possibly destroy the person she loves most?
