Two hundred years before Columbus, the cliff-dwelling Anasazi Indians built great stone cities in the American Southwest. Hunters and mystics of many clans roamed the desert. Viking explorers made their way across the territory while, from the vast Toltec kingdom of the south a mysterious trader, acclaimed as a fertility god by the clanswomen he visited, traveled from tribe to tribe. Kwani is driven from her tribe and embarks on a journey through the Southwest looking for her Viking forebears.
