Title: Callsign
Subtitle: King - Book 1
Description: The fabled Elephant Graveyard has been discovered. It contains enough ivory to make Ethiopia a wealthy nation. But the cave contains more than physical riches--it also holds the means to control the world. Fifteen scientists enter the cave. Only one leaves.

Jack Sigler, Callsign: King (field leader of the covert, black ops Chess Team) receives a cryptic text from Sara Fogg, his girlfriend and CDC "disease detective". A catastrophic disease has been reported in Ethiopia's Great Rift Valley, but Fogg suspects something more is going on. Her suspicion is confirmed when King's arrival in Africa is met by a high speed assassination attempt.

As King fights against two competing, high-tech mercenary forces, each struggling for control of the deadly discovery, Fogg disappears. Working with the surviving member of the science team that made the discovery, King begins a search for Fogg and the source of the potential plague that takes him back to the Great Rift Valley, back to the Elephant Graveyard, and brings him face-to-face with modern man's origins.
