“That’s just a taste of what’s to come,” the Overseer warned.“Now throw down your weapon and I’ll tell them you have promise. That you belong with us.”

No statement he made could have enraged Deci more. With his face twisted into a mask of hate, he lunged again, raising his wounded arm as a shield and thrusting the primitive knife toward the Overseer’s stomach. He managed to rip into the safari vest and draw some blood, but the Overseer shoved him aside and brought the machete down hard.

Deci’s hand was taken off at the wrist, and he tumbled to his knees. He scuffled away, retreating like a beaten animal.

Tired of the game, the Overseer looked at the dogs. “Mord!” he shouted, issuing the command to attack.

Two of the dogs shot forward, charging at Deci without hesitation. They hit him nearly simultaneously and he rolled with the impact. Another roll seemed deliberate, and then all three went over the edge.

They heard barking and howls as the animals fell. It was followed by sudden silence. An eerie quiet spread across the clearing. The men seemed unsure what to do.

The Overseer moved to the edge of the cliff and glanced downward. Deci and the two dogs lay battered and broken a few feet from each other, splatters of blood marking their impact points.

Looking down, it dawned on the Overseer that Deci had sacrificed himself. More than that, he’d come up with a complex plan, made a weapon, led a mini-rebellion, and chosen to die for a concept he couldn’t possibly understand: freedom.

They were learning things they hadn’t been taught. And doing so faster than anyone had a right to expect. This, he would have to report.

“Fan out,” the Overseer snapped. “Find the others. Look in the trees and the bushes. Look under every rock. They have to be here somewhere.”

With new urgency, the men, and the surviving dogs, rushed into the tropical brush, desperate to pick up a new trail.

The Overseer lingered at the cliffside, silently impressed with Deci’s choice to go out fighting. He gazed at the ocean. The sunlight was streaming through a line of clouds on the horizon, its beams visible in the contrast between light and dark. There was nothing else to see. No ships, no land, nothing but the endless, golden sea.

It made him wonder where they thought they were escaping to. This island,the rooms, the Overseer, and the Providers—this was all they knew. All they had ever seen.

He briefly wondered what their primitive brains would think if they did reach the web of complexity, chaos, and madness that men calledcivilization. Probably, he guessed, they would wish they never had.

Howls and barking from deep in the brush interrupted his reverie, and the Overseer reverted to the task at hand. He turned away from the sea and went back down the path, pleased to know that the hunt was still on.

Chapter 1

Reunion Island, Southern Indian Ocean

The island of Reunion—orLa Réunion, as the locals called it—sat in the tropics five hundred miles east of Madagascar and nearly two thousand miles due south of Saudi Arabia. A domain of France, it was a natural paradise as dramatic and beautiful as the famed island of Tahiti. It boasted stunning volcanic peaks, rainforests of brilliant green, and smooth, black sand beaches made from eroded lava that had been ground to dust by the waves.

Despite the appearance of a deserted tropical isle, Reunion was home to nearly a million French-speaking citizens. It drew tens of thousands of tourists every month and, according to some, nearly as many sharks.

Because of its location, Reunion acted like a rest stop on an oceanic path linking the waters of Australia and those of South Africa. Marine biologists called the route Shark Highway, as it was traveled heavily by great whites, bull sharks, makos, and hammerheads. As a result, the little French island in the Indian Ocean had become the shark attack capital of the world, dealing with dozens of attacks every year and scores of fatalities.

Unhappy with the nickname their island had earned, Reunion’s government took action, stringing nets around certain beaches to cordon them off from the sea while imposing strict no swimming/no surfing rules outside the protected zones. The program reduced the number of attacks dramatically, eventually culminating in a full year without any fatalities.

It was a stunning success, but no one really believed the ocean-dwelling predators were gone. No one, that is, except an American named Kurt Austin.

Kurt was a tall man of around forty, with broad shoulders and a lean build. He was the director of Special Projects for an American government agency known as NUMA, the National Underwater and Marine Agency, which operated around the world performing scientific research, locating sunken ships, and working with other nations on issues involving the sea.

In a joint effort with the University of Reunion, Kurt and his colleague Joe Zavala had spent the last six weeks in, on, and under the waters around Reunion, running a study on the shark population. Strangely enough, they’d had a hard time finding any, traveling farther and farther out to sea in search of significant examples to tag.

Bait hadn’t drawn the sharks. Recorded sounds of struggling fish hadn’t drawn them in. Even buckets of blood and a floating tuna carcass they’d come across hadn’t brought anything larger than a few juveniles to the table. It was as if the rest stop had closed its doors and all the adult sharks in the community had moved on.

It was a puzzling discovery, one that Kurt wrestled with even as he stood in the main departure lounge in Roland Garros Airport, waiting for the arrival of the long-haul aircraft that would take him and Joe off the island and away from the mystery. Had there not been other obligations waiting for them back in Washington, he would have canceled the trip home and stuck around in search of answers.

A tap on the shoulder broke his reverie. Turning to look, he found no one behind him, only a small metal pointer with four rake-like fingers protruding from it. The telescoping device led back to his closest friend, Joe Zavala, who sat at a high-top table with a hefty club sandwich and a stack of pommes frites in front of him.

Having drawn Kurt’s attention, Joe retracted the lightweight aluminum back scratcher and tucked it in his pocket. Kurt recalled Joe buying the device for five dollars at a kiosk the day they arrived. “I can’t believe you got through security with that thing.”

“This,” Joe insisted, “is a useful tool. It’s made my life easier in every way. For example, I didn’t even have to get off my seat to bother you.”

“Not sure that’s a good thing.”
