sleeping bag, frantic to move away from the pain. It was a re†ex as basic as lifting your hand off of a ‚re, but these embers were inside her. The machine plague. She knew that but she moved anyway, screaming in the dark.
“Get up! Get up!”
The stars were intense, close and sharp, like a billion fragments of light. Even through the bronze lens of her goggles, Ruth could see the neat, open canyon of the residential street around her—but as she tried to stand, she cracked her knee on something. Then the ground rocked and clanged beneath her. She nearly fell. She grabbed with both arms and struck Newcombe as he sat up.
The two of them were in the truck bed of a big Dodge pickup, she remembered. They’d found a boat at last, well before sunset, but spent forty minutes looking for a vehicle capable of towing it. Negotiating the truck through the ruins cost them another hour. By then they were losing daylight and Cam suggested using the truck itself for camp, two of them sleeping as the third stood guard. The tires were as good as stilts and they’d soaked the road beneath with gasoline in case ants or spiders came hunting.
“What—” Newcombe said, but he stopped and stared at his gloved hands. “Christ.”
He felt it, too.
“We’re in a hot spot!” Ruth cried, wrenching her bad arm as she staggered up again. “Cam? Cam, where are you!? We have to get out of here!”
A white beam slashed across the darkness from inside the long, thin ‚shing boat, parked on its trailer. Then the †ashlight jogged higher, re†ecting on the beige paint as Cam stepped onto the bow. “Wait,” he said. “Take it easy.”
“We can’t—”
“We’ll go. Just wait. Get your stuff. Newcombe? We’d better splash ourselves with more gasoline. Who knows what the hell else is awake right now.”
His methodical voice should have helped Ruth control herself. He was right. There were too many other dangers to run blindly into the night, but the pain was bad and growing worse and every breath carried more nanotech into their lungs.
Their ski gear was only designed to repel snow and cold. Jackets, goggles, and fabric masks could never be proof against the plague. In fact, the masks were nearly useless. They wore their makeshift armor only to reduce their exposure, but it was an impossible battle. Thousands of the microscopic particles covered each short yard of ground, thicker here, thinner there, like unseen membranes and drifts. With every step they stirred up great puffs of it, yet even holding still would be no help. They were deep within an invisible ocean. Airborne nanos blanketed the entire planet, forming vast wells and currents as the weather dictated, and this fog would be its worst down here at sea level. The wind might sweep it up and away, but rain and runoff and gravity were a constant drag on the subatomic machines. Newcombe hadn’t wanted to drink the water because he was afraid of bacteria, but even if he’d had puri‚er tablets, Ruth would have stopped him because this shoreline must be dense with the machine plague.
Their only true protection was the vaccine nano. But it could be overwhelmed. In an ideal scenario, it would kill the plague as soon as the invader touched their skin or lungs. In reality, its capacity to target the plague was limited, and it functioned best against live, active infections. That was a problem. Inhaled or otherwise absorbed into a host body, the plague took minutes or even hours to reactivate, and in that time it could travel farther than was easily understood. A human being was comprised of miles upon miles of veins, tissue, organs, and muscle—and once the plague began to replicate, the body’s own pulse became a weakness, distributing the nanotech everywhere.
The vaccine was not so aggressive. It couldn’t be. It was able to build more of itself only by tearing apart its rival. Otherwise it would have been another machine plague. Ruth had taught it to recognize the
