In a Tirio village deep in the heart of the Amazon rain forest, the shaman Nahtahlah has a place of honor in his tribe. Young Kamanya wants to learn the healing secrets of the forest plants—he hopes that he, too, will become the tribe's shaman, so that he can cure his people. When the villagers fall sick with an illness that Nahtahlah cannot cure, many lose faith in the shaman's wisdom—until a foreign woman helps them understand its value while giving Kamanya an opportunity to realize his dream. Lynne Cherry returns to the rain forest with ethnobotanist Mark J. Plotkin to tell an important story about the healing plants of the earth-and why we must protect them.
