Here is a perceptive coming-of-age story about rivalry, trust, betrayal, and blackmail among a precocious group of sixth graders who are vying for popularity. Laura and her girlfriends create the Pig City Club at her school. But the club is secret, and to ensure that no one spills the beans, the members take out "insurance" and tell Laura one secret about themselves. Anyone who talks about the club will have her secret told to the entire school. But when Laura allows Gabriel, a boy in her class, to join the club, a rival club is formed, and the Pig City girls are embarrassed when their insurance secrets are revealed. A web of betrayal is spun! Sachar uses his trademark humor to reveal a common social phenomenon in adolescent life, and readers in this stage of their lives may recognize their classmates or themselves in this engaging read.
