Giles, Gail. What Happened to Cass McBride? 2006.
This was a great book! This book alternates perspective between Cass, who is currently buried alive; Kyle, who is now in jail; and Ben, the cop working the case. Kyle has buried Cass alive because he blames her for the death of his brother David. David was a shy kid who had a hard time at home, dealing with constant criticism from his mother. When he asks Cass out on a date, she is polite to him but writes a note to her friend telling her how David was a loser and had just asked her out. David read the note and then killed himself by hanging himself from the tree in his front yard. Blaming her for the death, Kyle decides to bury her alive to torture her like her brother had been tortured his whole life.
This was a great novel that really gets into the heads of all of the characters. The reader will be fascinated by all of the characters and won't want to put the book down until they get to the end.
