From the Pulitzer Prize-winning New York Times journalist and author of A Deadly Wandering comes a pulse-pounding technological thriller—as ingenious as the works of Michael Crichton and as urgent and irresistible as an episode of 24—in which one man has three days to prevent annihilation: the outbreak of World War III.

Computer genius Jeremy Stillwater has designed a machine that can predict global conflicts and ultimately head them off. But he’s a stubborn guy, very sure of his own genius, and has wound up making enemies, and even seen his brilliant invention discredited.

There’s nowhere for him to turn when the most remarkable thing happens: his computer beeps with warning that the outbreak of World War III is imminent, three days and counting.

Alone, armed with nothing but his own ingenuity, he embarks on quest to find the mysterious and powerful nemesis determined to destroy mankind. But enemies lurk in the shadows waiting to strike. Could they have figured out how to use Jeremy, and his invention, for their own evil ends?

Before he can save billions of lives, Jeremy has to figure out how to save his own. . . .

Read an excerpt:


“Salam, your majesty.”

The woman taps on the quadruple-paned glass, well thick enough to swallow her whisper and the greeting of her index finger.

The beast behind the glass does not stir. It is rolled on its side, heavy eyes closed, heavy paws strewn before it, lazy with confidence, even in sleep.

A hat pulled tightly over the woman’s short black hair does little to protect her from the pre-dawn chill. Nor detract from her radiance. From the pocket of a wool black knee-length coat, she pulls a hard-earned skeleton key.

Without taking her eyes from the animal, she takes three steps to her left. She stops in front of the tall bars of the cage door. She inhales the scent of damp fur and old meat. She inserts the key. The lion twitches.

She thinks: San Francisco is supposed to be so humane. A zoo is a zoo. She turns the key. The lion lifts his head. He draws open an eyelid. Blinks.

The woman slightly bows her head. “Guardians of the City. At your service.” Her accent carries generations of migration, ports of call, millennia of weariness and duty.

The lion flops over, facing the woman now, but still in repose. The woman smiles. She understands this to be the most docile time of the lion’s day. She pushes open the door.

The lion springs. The door slams against its liberator.

“Salam,” she expels the word with a laugh.

Feels razor claws reaching her through the bars.

Salam, she thinks. At last. Peace.
