Sixth Grade Secrets is a novel by Louis Sachar that follows sixth-grader Laura Sibbie and her friends as they create a secret club in violation of school rules. Laura aspires to be a leader and learns the three Rs of what leadership can entail – Relationships, Rivalries and Responsibility. In 2009 it was released by Bloomsbury Publishing in the United Kingdom under the title, Pig City.
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 (who 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.
