Justine McKeen is back, and she's on a deadline. With only days left before Earth Day, Justine enlists the help of her classmates to count flower buds, frogs, spiders and ants in their natural habitat as part of an environmental science project. But there's a species right in her own classroom that she'll have to tackle first: a class bully. Savannah Blue, aka the Queen of Mean, criticizes Justine's secondhand clothes and calls being green a waste of time. Their teacher, Mrs. Howie, gives the girls a new assignment for Earth Day. They must present together to the class on why it's important to care for the environment. In the sixth book in this bestselling series, Justine is up against her biggest challenge yet. Can she convince the Queen of Mean to go green?
