A car flies out of the night, taking aim at a stranger crossing a lonely street, empty except for a single witness: Dr. Dallas Roark. In an instant, car and stranger meet, and the impact sends a stunned Dallas tumbling down a path that would change his life forever. Before dying, the mortally wounded man gives his briefcase to Dallas, along with a single message: "find the Guardians." This final request sets in motion a series of events that challenge Dallas, a linguist and archaeologist, to re-examine everything he thought he knew. Looking inside the case, Dallas finds a triangular emerald tablet engraved with an indecipherable cuneiform script. Along with the tablet, Dallas finds clues that lead him to the Guardians, an ancient organization dedicated to the protection of the human race. When Dallas reveals to the Guardians that he possesses the tablet, they are forced to divulge to him both humanity's hidden history, and the consequences of this knowledge; a reality that they feel the human race is not yet ready to face. He immediately becomes a target for their adversaries - another secret society called the Order. Now there is no turning back; Dallas must join the Guardians in their quest for the treasures of the Anunnaki. With the help of Jorge, Miranda, Raj, and the rest of the team, Dallas pursues the mystery from the United States, across Africa, and into the Middle East in a race to discover the ultimate truth about the history and fate of mankind. Dallas must summon all his skill, knowledge, and intuition if he is to rescue humanity from a fate decreed over thirteen millennia ago. Can he decipher the mysterious emerald tablet, solve its ancient riddle, and save both the worldand himself?
