William Boone. When the Taelons came to Earth, he was tapped to be the human who would work most closely with Da'an, the mysteriously powerful and enigmatic leader who speaks for the alien Companions.

Boone became many things: confidant, bodyguard, interpreter...and undercover agent for the human Resistance. But little has been told of Boone's past, of the events that prepared him for this perilous assignment.

Now it is revealed: from his duty overseas during the S/I War to his life in the United States, from the arrival of aliens on Earth to his first encounter with the mysterious Augur, here for the first time is the story behind mankind's first double agent in the underground war between human and alien--and the Resistance's first martyr.
