Ammi Leong, an independent freelance children’s book illustrator, joined forces with Jo Leen and her team of Langur Project Penang in voicing out for the dusky langurs and wildlife residents in Penang. Hence Ammi followed Jo Leen into the forest to learn about the lives of the dusky langurs and spent months illustrating the hard work of Jo Leen in pushing for the canopy bridge initiative in Malaysia. A portion from this book sale profit will be donated to Langur Project Penang (LPP) for dusky langur research, conservation, and education work.
