Scientists call them "Inia geoffrensis," an ancient species of toothed whale whose origin dates back about 15 million years. To the local people of the Amazon, pink river dolphins are "botos," shape shifters that, in the guise of human desire, can claim your soul and take you to the Encante, an enchanted underwater world.As tributaries braid into a single river, "Journey of the Pink Dolphins" weaves ancient myth and modern science into one woman's search for these elusive creatures. Over four separate journeys, Sy Montgomery follows the dolphins, tracing their spiritual, historical, and environmental past, present, and future. Ancient legends tell us that dolphins have guided humans for millennia, and in "Journey of the Pink Dolphins," Montgomery answers their call, taking us to that perfect place where the Amazon melts into the forest, dolphins swim among treetops, and the twenty-first century dissolves into the beginning of time.
