When 12-year-old intrepid explorer Chang discovered bear poaching near her home in Vietnam, she decided to do everything she could to become a wildlife conservationist. After training herself in wilderness survival skills, documenting her adventures in her field notebook, and disproving all the critics who thought she wasn't old enough, strong enough, or fluent enough in English Chang was finally accepted as a rescue center volunteer. But her toughest challenge comes when she's tasked with returning Sorya - the sun bear she raised from infancy - to the wild where she belongs. Because despite being a different species, Sorya is Chang's best friend. And letting a friend go is never easy, even when it's the right thing to do.
