Tom Duncan—Callsign: Deep Blue, former Army ranger, former president of the United States and handler of the black ops force known as Chess Team, is visiting the team’s new secret headquarters. The underground facility, known as Alpha, once belonged to Manifold Genetics, a corrupt corporation shut down by Chess Team. But despite being abandoned for years, Alpha still hides secrets. Security doors slam shut and lock, sealing Duncan and his assistants inside. As Matt Carrack, the leader of Duncan's security team, attempts to gain access, Duncan discovers they are not alone inside the abandoned facility. High tech intruders have infiltrated the base, their goal unknown. But a far greater threat rises from the subterranean depths beneath Alpha—failed regenerative experiments from the days of Manifold, and they’re fast, hostile and hungry. While the security team are beset by ingenious death traps, determined mercenaries and vicious creatures that defy their imaginations, Duncan and his personal bodyguard must battle the growing tide of creatures, stave off the incursion of enemy forces and prevent the violent intruders from releasing the horror currently contained inside Alpha, to an unsuspecting outside world. And as the battle rages, a bomb quietly counts down in the shadows. THE CALLSIGN BOOKS: Callsign: Deep Blue: (38,000 words) part of a series of Chess Team novellas being released in 2011.
