Emma Caroline Blake is known at Ridgemont Academy for getting straight As, leading student clubs and winning at multiple sports. But her life falls apart when she loses her sister, along with any hope for the future. The high schooler is soon unrecognisable from the happy, active girl she used to be. When Emma’s assigned an essay in English class, all her pain and fear and sadness come pouring out in the form of a fierce challenge. You—all of you—are sleepwalking through global catastrophe. And I intend to wake you up. What Emma says she plans to do is horrifying. The students are in shock. So are the teachers. The only way to save her will be for them to study the page torn out of Emma’s own lesson plan – then act on it.
