Sixth Grade Secrets
Louis Sachar
 When Laura Sibbie starts a secret club at school, she makes the other members give her something totally embarrassing as "insurance," to make sure they don't tell anyone else about the club. She promises to keep the insurance secret, unless someone blabs. Gabriel wants to join, but when Laura asks him, there is a misunderstanding and he storms out to form a rival club, Monkey Town. The pranks they play on each other escalates into ugly and destructive acts. It gets to a point where Gabriel steals the insurance, and reveals it to the school. Sheila (whom hates Laura) and a friend, Howard, corner Laura on her way from school and cut a large chunk out of her long hair. Laura gets a new, short, curly hair style which Gabriel, arriving with daisies, likes. The sheared Laura sees how foolish they've been, and the truth of Gabriel's affection comes to light.
