Kyle Kirby has planned a cruel and unusual revenge on Cass McBride, the most popular girl in school, for the death of his brother David. He digs a hole. Kidnaps Cass. Puts her in a box--underground. He buries her alive. But lying in the deepest dark, Cass finds a weapon: she uses the power of words to keep her nemesis talking--and herself breathing--during the most harrowing 48 hours of her life.
