Dr. Hunter Johnson is about to get a sign that will change his life forever. It begins with eighteen consecutive nights of the same disruptive dream, followed by eighteen seemingly random words, and ends with a telephone call from a non-human voice mandating his death. Hunter and his son, Scott, have been recruited to take part in a strange, otherworldly duel to the death, and they have no choice but to press on at great peril to their lives. So begins the partnership of Hunter and Scott, with a time-traveling alien named LEAX. Their mission is to locate a powerful new time travel technology hidden in the past along Route 66. They begin in Lupton, Arizona, and soon learn of the time-traveling Oent'rfazr race and their evil adversaries, the B'stri.. They search Route 66 for living, alien mapRocks and in the process become time travelers themselves. They visit Arizona's lost past, including the site of a shootout with the Clantons before they met the Earps at the O.K. Corral and a visit to a city where the federal government intended to detonate twenty atomic bombs. Their four hundred-mile journey across Arizona reveals more about history and time travel than either could imagine-and more about their pasts and futures than they can possibly understand or believe.
