Book excerpt: For centuries, the Chieftain of Wakanda (the Black Panther) has gained his powers through the juices of the heart-shaped herb. Much like Vibranium, the heart-shaped herb is essential to the survival and prosperity of Wakanda. But something is wrong. The plants are dying. No matter what the people of Wakanda do, they can't save them. And their supply is running short. It's up to Shuri to travel from Wakanda in order to discover what is killing the herb, and how she can save it. Aligned to Common Core Standards and correlated to state standards.
