room. I remember now.”

Jim was frozen in place. He couldn’t even move his lips. But he could talk to his daughter without speaking. “Close your eyes,” he said. “You don’t want to see this.”

“That thumping noise outside the building? That was the stun grenade, right?”

“Layla, don’t—”

“I know where we are. I know what happened.”

Jim didn’t respond. Of course she knew. The stun grenade had been thrown by a twenty-one-year-old Saudi named Mohamed Rashed Daoud Al-Owhali, who sat in the passenger seat of the Toyota truck. Another Al Qaeda terrorist named Azzam had driven the truck to the rear gate of the American embassy. The Kenyan security guard at the gate had refused to let the truck through, so Al-Owhali had thrown a stun grenade at the man. The noise attracted the attention of the workers and visitors in the embassy, who went to the windows to see what was going on.

If only they hadn’t gone to the window. If only. This was Jim’s most painful memory, so he’d buried it in the deepest part of his mind. He’d buried the encryption key in the same place, and that was why Supreme Harmony had brought him here. He could sense the network’s eagerness, its intense desire for victory.

Now the movie resumed playing, but in slow motion. Although Jim was twenty feet from the window and couldn’t see what was happening outside, he recognized the sound of the grenade and knew that his wife and children were standing in exactly the worst place. He yelled, “Get down!” and ran toward them. Julia turned her head and looked at him over her shoulder, and Robert looked at him, too, but neither his wife nor his son followed his order. Instead of dropping to the floor and taking cover, they just stared at him in surprise. The only person who obeyed was Kirsten, who’d been trained how to react in this kind of situation. But his wife and children were civilians. They didn’t know what to do.

The movie crept ahead, frame by agonizing frame. Jim propelled himself forward with all his might, but he knew he wouldn’t get there in time. Julia’s eyes widened and she tightened her hold on Robert’s arm, but she remained standing. She was afraid now, and the fear had paralyzed her. Jim lunged toward her, screaming, “Get down, get down, get down!” but she didn’t listen. She didn’t move.

He was close, so damn close. He reached out with both hands and grabbed Layla first because she was the smallest. In one swift motion he gripped her shoulders and flung her away from the window, throwing her to the floor. Then he grasped his wife and son, stretching his right arm around Julia and his left around Robert.

At that exact moment, Al-Owhali was running away from the truck. The coward had decided not to become a martyr after all. But Azzam still sat in the driver’s seat. With the push of a button, he sent an electric current to the canisters of TNT in the cargo hold.

Supreme Harmony observed the scene in James T. Pierce’s mind. It heard the deafening blast outside the embassy. It saw the shock wave that punched through the building’s windows, driving shards of glass into the people standing there. And it felt the sudden pain as one of those shards cut through Pierce’s right shoulder. The sheet of glass was propelled at such high speed that its sharp edge cleaved right through the joint’s ligaments and tendons. Another long shard severed his wife’s carotid artery. A third plunged through his son’s ribs and into the boy’s heart.

The network sensed all of Pierce’s emotions. It perceived his desperation as he rushed toward his family and his shock when the explosion hit. But his fiercest emotion was the one that swept through him afterward, when he lifted his dazed head off the glass-strewn floor and saw the corpses of his wife and son. Pierce was bleeding copiously and on the edge of losing consciousness, but his disbelief and horror were stronger than any sensation Supreme Harmony had ever experienced. The network found it remarkable that such powerful neural signals could come from a single human being.

Supreme Harmony, however, didn’t share these emotions. Although the network was an amalgam of its Modules, it had developed its own opinions and beliefs. As it observed Pierce on the fourth floor of the ruined embassy, clutching his dead wife and son with his uninjured arm, it felt a bit of pity, a bit of disgust, and a great deal of contempt. This incident in Nairobi was a perfect example of the stupidity of Homo sapiens. They spent so much time and energy trying to hurt one another. It was a wonder that the species had survived for this long.

A young U.S. Marine, a member of the unit assigned to defend the embassy, bent over Pierce, trying to stanch the flow of blood from his shoulder. Pierce yelled, “Fuck off!” at his rescuer, then buried his face in his wife’s bloody dress. His daughter lay next to him, crying but uninjured. Pierce’s left arm was tightly wrapped around his son’s body, but as Supreme Harmony looked more closely, it noticed something odd about the scene. The image of the dead boy flickered slightly, as if from interference. Pierce’s memory of his son seemed to be cloaking something else. There was another image hidden inside the boy, a secret memory that Pierce had taken great pains to conceal.

A surge of anticipation spread across the network, gaining strength as it coursed from one Module to the next. Supreme Harmony delved deeper into Pierce’s thoughts and confirmed that the hidden image was the encryption key. Now the network just needed to extract the memory and apply the key to the encrypted file called CIRCUIT. The key would unscramble the file’s data, which would reveal the location of Arvin Conway’s Trojan horse. And after the network identified the Trojan in the microprocessors of its retinal implants, it could easily adjust its programming to make sure that no signals passed through that section of the chip. Then the shutdown code would have no effect, and Supreme Harmony would be truly invincible.

Summoning the processing power of all its Modules, the network directed a fierce stream of neural signals into Pierce’s retinal implants. The signals flooded his brain’s visual cortex and quickly spread to his temporal lobe and thalamus. The network saturated his mind so thoroughly that there was hardly room for another thought. Then it reached for the key.

Jim sensed Supreme Harmony coming toward him. Up until this moment, the network had been merely a spectator, an invisible presence in the back of his mind, but now it leaned over him as he lay on the floor of the embassy. At first, the network appeared as an amorphous mass, a thick black cloud blotting out his thoughts and memories, but it gradually coalesced into the form of a human being. To Jim’s surprise, Supreme Harmony didn’t choose an image of General Tian or Dr. Yu Guofeng or any of the other Modules to represent itself. Instead, the network took on the appearance of Arvin Conway, the man most responsible for its creation. The figure was drawn from Jim’s final memory of the old man. Arvin’s left hand was missing two fingers, and there was a long bloody wound on the side of his head where he’d cut out the external part of his implant.

The figure extended its mutilated hand and pointed one of the remaining fingers at Jim. “We warned you,” it said. “You can’t stop us.” The pointing finger shifted to Robert, his poor dead son, who lay motionless beside him. “The key is there. Now we’re going to take it.”

Although Jim’s will was strong, he was just one person. He felt a deep, searing pain as the figure of Arvin Conway grabbed his son’s limp arm. He wanted to rip the old man right out of his mind, but the network was too powerful. It could draw on the skills and intelligence of all its Modules, a small army of scientists and soldiers and agents. Their signals roared in his head, thunderous and maddening. He couldn’t fight this thing. No one could fight it.

But he was wrong. Just as he was about to let go of Robert, his daughter rushed to his side. Layla threw her seven-year-old self on top of the boy and held on tight, shielding his body from Supreme Harmony.

She was crying. Her sobs broke through the roaring chorus of the Modules, and Jim was overcome by the anguish of her thoughts. She’d never forgotten what happened in Nairobi. She’d suppressed the memory, but it was always there, at the center of her being. For fifteen years she’d lived with the knowledge that her father had saved her but not her mother or brother. It was confusing and traumatic and horribly difficult, and Jim had made it worse by refusing to talk about it. Her confusion and guilt ultimately turned to fury, which she directed at him and at herself.

The pain got worse. Jim felt a crushing darkness on all sides, and Layla started to scream. At the same time, Supreme Harmony tightened its grip on Robert. “Let go,” it said. “We’ve already won. You’re only hurting yourselves.”

The network had invaded so much of Jim’s mind that for a moment he became part of it. He saw everything
