For thirty years David G. Campbell has explored the Amazon, an enchanting terrain of forest and river that is home to the greatest diversity of plants and animals to have ever existed, anywhere at any time, during the four-billion-year history of life on Earth. With great artistic flair, Campbell describes a journey up the Rio Moa, a remote tributary of the Amazon River, 2,800 miles from its mouth. In elegant prose that enchants and entrances, Campbell has written an elegy for the Amazon forest and its peoples-for what has become a land of ghosts.
