Years pass and the mystery persists: an enduring torment for the teenage Christine Gray, the last person to see Vivian alive. Perhaps if shed shown the girl a little kindness, and seen her safely home, Vivian might still be with them? Yet when someone claiming to be a grown-up Vivian returns to the land of the living, the enigma seems only to deepen, threatening to consume the wicked and innocent alike.
