In a future where faith is obsolete and the mentally ill are removed from society, Tess Eckhart is terrified she's losing her mind. After a public breakdown at a high school party, her parents are terrified too-enough to uproot their lives and move across the country, next to a private facility that might be her only hope.

Tess is determined to fit in at her new school, to ignore the whispers and stares. But when it comes to Luka Williams, a reluctantly popular boy in her class, she's unused to a stare that intense. Then the headaches begin. The prophetic dreams. The creeping sense that something inside her is unraveling. As Tess fights to keep it together, she can't shake the suspicion that Luka knows what's happening-that he might even be responsible.

But what if she's wrong? What if Luka Williams is the only thing standing between her and a madness too terrifying to fathom?
