Heading to Tucson, Arizona with his son Grant, Wolter is eager to investigate a mysterious cache of crosses, swords and other relics pulled from the desert in the 1920s. One sword has a date–800 AD–written in Latin, which would suggest a group of Europeans was in the American Southwest hundreds of years before Columbus made it to America. Wolter’s investigation is particularly important for one man–the grandson of the man who helped discover the items. The investigation could determine whether the artifacts are part of an elaborate hoax or part of a find that could change history.
