FACT
The world's largest scientific research facility-Switzerland's Conseil Européen pour la Recherche
Nucléaire (CERN)-recently succeeded in producing the first particles of antimatter. Antimatter is
identical to physical matter except that it is composed of particles whose electric charges are opposite to
those found in normal matter.
Antimatter is the most powerful energy source known to man. It releases energy with 100 percent
efficiency (nuclear fission is 1.5 percent efficient). Antimatter creates no pollution or radiation, and a
droplet could power New York City for a full day.
There is, however, one catch . . .
Antimatter is highly unstable. It ignites when it comes in contact with absolutely anything . . . even air. A
single gram of antimatter contains the energy of a 20-kiloton nuclear bomb-the size of the bomb
dropped on Hiroshima.
Until recently antimatter has been created only in very small amounts (a few atoms at a time). But CERN
has now broken ground on its new Antiproton Decelerator-an advanced antimatter production facility
that promises to create antimatter in much larger quantities.
One question looms: Will this highly volatile substance save the world, or will it be used to create the
most deadly weapon ever made?

PROLOGUE
P hysicist Leonardo Vetra smelled burning flesh, and he knew it was his own. He stared up in terror at
the dark figure looming over him. "What do you want!"
"La chiave," the raspy voice replied. "The password."
"But . . . I don't-"
The intruder pressed down again, grinding the white hot object deeper into Vetra's chest. There was the
hiss of broiling flesh.
Vetra cried out in agony. "There is no password!" He felt himself drifting toward unconsciousness.
The figure glared. "Ne avevo paura. I was afraid of that."
Vetra fought to keep his senses, but the darkness was closing in. His only solace was in knowing his
attacker would never obtain what he had come for. A moment later, however, the figure produced a blade
and brought it to Vetra's face. The blade hovered. Carefully. Surgically.
"For the love of God!" Vetra screamed. But it was too late.

H igh atop the steps of the Pyramid of Giza a young woman laughed and called down to him. "Robert,
hurry up! I knew I should have married a younger man!" Her smile was magic.
He struggled to keep up, but his legs felt like stone. "Wait," he begged. "Please . . ."
As he climbed, his vision began to blur. There was a thundering in his ears. I must reach her! But when
he looked up again, the woman had disappeared. In her place stood an old man with rotting teeth. The
man stared down, curling his lips into a lonely grimace. Then he let out a scream of anguish that
resounded across the desert.
