Mallory McDonald is going green! As an official member of the Fern Falls Elementary Environmental Committee, Mallory is super excited to make her school and home more environmentally friendly. She s even selected to be class representative for the all-school Green Fair. But the minute Mallory goes green, everything goes wrong. No one wants her "expert" opinion on how to help the environment. Her classmates don t want to participate in the Green Fair project she s created. And worst of all, by the time the fair rolls around, many of them aren t even speaking to Mallory. Can Mallory find a way to save the planet and her friendships?
