Raised at the Institute for Paranormal Dysfunction to test Dr Alex Harmon's theories, Leeth's magic took everyone by surprise. And now, she and her abusive guardian have been taken by a covert government agency where Leeth is training to become their assassin.
But Leeth is both more dangerous than they know, and too innocent for her own good. Sent "back" to school to learn some much-needed social skills - under strict instructions not to kill - Leeth is singularly ill-equipped to deal with the challenges of a normal life.
She wants to belong, but has little idea how to fit in - let alone how mean girls can be.
Nor does she know that an uncanny and ruthless killer, the product of a madman's insane magic, hunts her.
Leeth has some harsh lessons to learn.
She'd better learn fast.
