The animals of the forest are all getting sick and no one can figure out why. Determined to get to the bottom of the mystery and help her friends and family, Charlotte dives into some serious medical science. But when the doctors and other scientists don't take her work seriously, she sets out to find a cure on her own, determined to show that she can make a difference. This empowering story about a smart, confident bunny encourages girls to be persistent and believe in themselves.

Charlotte is a serious scientist. She solves important problems by following the scientific method. She has all the right equipment: protective glasses, a lab coat, a clipboard, and a magnifying glass. What she doesn't have is space. She has so many brothers and sisters (she is a rabbit, after all) that she is too squished to work on her experiments! Can she use science to solve her problem?
