This picture book biography tells the story of Meg Lowman, a groundbreaking female scientist called a real life Lorax by National Geographic, who was determined to investigate the marvelous, undiscovered world of the rainforest treetops.

Meg Lowman was always fascinated by the natural world above her head - the colors, the branches, and, most of all, the leaves and mysterious organisms living there. Meg set out to climb up and investigate the rain forest tree canopies - and to be the first scientist to do so. But she encountered challenge after challenge. Male teachers would not let her into their classrooms, the high canopy was difficult to get to, and worst of all, people were logging and clearing the forests. Meg never gave up or gave in. She studied, invented, and persevered, not only creating a future for herself as a scientist, but making sure that the rainforests had a future as well. Working closely with Meg Lowman, author Heather Lang and artist Jana Christy beautifully capture Meg’s world in the treetops.

Meg Lowman or ‘Canopy Meg’ is a true hero, a courageous explorer, who made amazing discoveries high in the forest canopy. The Leaf Detective captures the magic of that little-known world with its clear, informative text and fabulous illustrations. Young readers everywhere will be fascinated and inspired to learn more about nature. -Jane Goodall, PhD, DBE, Founder of the Jane Goodall Institute and Pioneer of Peace

Margaret Lowman is a pioneer scientist in a discipline that demands exceptional imagination, courage, and physical rigor. But of equal importance, she has created an extraordinarily important branch of environmental and conservation research. Heather Lang and Jana Christy, in this charming introduction, have invited us to climb on up and visit her. -Edward O. Wilson, Pulitzer Prize winner and Professor Emeritus, Harvard University
