The award-winning author of The Most Magnificent Thing introduces the value of science and inquiry to young readers with humor and heart. For fans of Ada Twist, Scientist and Hidden Figures. Esther the fairy doesn't believe in magic. But fairies are all about magic, despite Esther's best efforts to reveal the science of their world. No matter how she and her bird, Albert, explain that rainbows are refracted light rather than a path to gold, or that mist is water evaporating rather than an evil omen, or the importance of the scientific method, her fairymates would rather just do magic. So when the other fairies' solution to helping a dying tree is to do a mystical moonlight dance, Esther decides to take it upon herself to resuscitate the tree . . . with the scientific method, some hypothesizing, a few experiments and the heady conclusion that trees need sunlight to live! But while Esther manages to save the tree, she can't quite change the minds of her misguided fairymates . . . or can she?
