Sixteen-year-old Sage is a lonely child. Her adoptive parents watch her obsessively, as if studying her for warning signs of...something. And maybe they're right to-even she can't make sense of the strange things she sees and hears. She possesses knowledge that other teenagers don't, that her parents and teachers-no adult-could possibly have. So when Sage finally makes a friend who understands her alarming gift, he becomes her confidant, a precarious link to the truth about who she really is. For Sage and the alluring new boy at school share many things in common. Perhaps, they'll learn, far too many things.
