Panther Shifter Jahzara Diouf has always wanted to be like her mother: become a doctor, save the world. Lately, though, she'd just like to survive until her eighteenth birthday. When caracals with purple eyes attack her tribe, Zara realizes there's more to the world than she thought. Before she can investigate, she's shipped off to a secret boarding school for Shifters, one that promises to be a safe haven. Until the students begin turning on one another, anyway. And it's not just teenage hormones and the threat of midterms. A creature lurks in the third-floor corridor-neither human nor Shifter. And only Zara can see it. Even worse, it's not the only one of its kind. They've been attacking Shifters around the world with one goal in mind: extermination. If she plans to see eighteen, Zara must take matters into her own hands and find a way to stop them. She always did want to save the world.
