The Far Hills Junior High war of the sexes is about to begin

Spring has sprung, but Madison has the seventh-grade superblues. She's behind on her homework, each of her parents has started dating again, and she forgets to have her mom sign the permission slip for the science-class field trip. Her feelings for her crush, Hart, get even more confusing when their science teacher divides the class into two teams for the trip—boys vs. girls—with a competition at the end. Now Madison is teamed up with the girls—including her nemesis, Poison Ivy—against her BFF Egg and, worst of all, Hart! But sometimes, even enemies have to come together to take first place.
