What would your average American family do with a fifteenth-century Renaissance genius? Take him to McDonald's, of course! And a lot more. It seems that Leonardo da Vinci will be staying with the Wagners, so the family takes a while to show him around twentieth century America. The Italian master learns much from his newfound family, experiencing the marvels of modern flight, communication, medicine, and more. But da Vinci discovers a dark side to the twentieth century, as well. Some people misuse science for evil ends; others reject it entirely. But da Vinci foresees a solution to the dilemma - his secret is revealed in The Millennium Man.
