Tehya is a young girl living on a Native American reservation in Washington State. One day, she notices a shiny, black liquid floating on the river near her home. Having her late grandmother's journal for comparison, Tehya knows that the liquid is out of place.
Meeting a team of environmental engineers, Tehya realizes that she must act quick. Each part of the ecosystem is connected, regardless of whether it is living or non-living. She knows the water cycle connects the land and water, and that the food web connects all living organisms.
Using a wide variety of materials, Tehya learns about how each technology could either contain or remove the oil from the river. Before long, Tehya is able to help save the ecosystem from further destruction!
