Everything you believe is wrong. Sixteen-year-old Alison wakes up in a mental institution. As she pieces her memory back together, she realizes she's confessed to murdering Tori Beaugrand, the most perfect girl at school. But the case is a mystery. Tori's body has not been found, and Alison can't explain what happened. One minute she was fighting with Tori. The next moment Tori disintegrated—into nothing. But that's impossible. No one is capable of making someone vanish. Right? Alison must be losing her mind—like her mother always feared she would. For years Alison has tried to keep her weird sensory abilities a secret. No one ever understood—until a mysterious visiting scientist takes an interest in Alison's case. Suddenly, Alison discovers that the world is wrong about her—and that she's capable of far more than anyone else would believe.
