Poison Potion

"Do you believe in magic? Lottie and her friends do! When they meet the Star Animals, a whole world of adventure unfolds. The Star Friends still don't know who is using the woodland plants to create dark magic potions. Could it be the grumpy new school secretary? Meanwhile, Lottie's friend Essie is being mean at school, and none of the adults want to go to work! The girls must combine their powers to unmask the potion-maker - and defeat them once and for all."--Publisher's description.
