The Two Worlds of Billy Callahan

The Two Worlds of Billy Callahan

Lost relics buried beneath the Israeli desert are supposed to be from human cultures-not aliens.
Billy Callahan, the son of Jack Callahan, one of the most recognized anthropologists and archaeologists the world has ever known, just stumbled upon something impossible: an ancient artifact from a civilization born among the stars. Before Billy can tell the world what he's found and change the course of human history, tragedy strikes, silencing him for decades.
Who would believe a kid? No one. But the message left by the alien race is a dire one, and the fate of humanity rests in Billy Callahan's unproven hands. Can he convince the world to listen? Or will the leaders of his own country simply destroy him and ignore the message?
