Each time, Mira refused to go.
“This won’t work,” Peter said. “We’ll have to go over the roof.” He turned to Hollis. “You go first. Olson and I can push you up.”
“I’m too heavy. Hightop should go, then you. I’ll lift Mira up.”
Hollis dropped to a crouch; Caleb climbed aboard his shoulders. The Humvee had swayed away again, Alicia firing in short bursts at the rear of the train. With Hightop on his shoulders, Hollis positioned himself at the edge of the door.
“Okay! Let go!”
Hollis ducked away, keeping one hand gripped on Caleb’s foot; Peter grabbed the other. Together they pushed the boy upward, propelling Caleb over the lip of the door.
Peter ascended the same way. From the roof of the car he could see that the mass of virals, having passed through the tunnel, had broken apart into three groups—one directly behind them, two following on either side. They were racing in a kind of gallop, using both their hands and their feet to propel themselves forward in long leaps. Alicia was shooting at the head of the central group, which had closed to within ten meters. Some went down, dead or injured or merely stunned he couldn’t tell; the pod closed over them and kept coming. Behind them the other two groups began to merge, passing through one another like currents of water, separating once again to re-form their original shapes.
He lay on his belly beside Caleb and reached down as Hollis lifted Mira up; they found the frightened girl’s hands and pulled, drawing her onto the roof.
Alicia, below them: “Get down!”
Three virals were on the roof of the last boxcar now. A blast of fire erupted from the Humvee and they jumped away. Caleb was already vaulting across the gap to the engine. Peter reached for Mira but the girl was frozen in place, her body pressed to the roof of the car, her arms hugging it as if it were the one thing that might save her.
“Mira,” Peter said, trying to pull her free, “please.”
Still she held on. “I can’t, I can’t, I can’t.”
From below, a clawed hand reached up, wrapping around her ankle. “Poppa!”
Then she was gone.
There was nothing else he could do. Peter dashed toward the gap, took it at a leap, and dropped through the hatch behind Caleb. He told Michael to hold the train steady and swung open the door to the cabin and looked aft.
The virals were all over the third boxcar now, clinging to the sides like a swarm of insects. So intense was their frenzy that they appeared to be fighting with one another, snapping and snarling for the right to be the first ones inside. Even over the wind, Peter could hear the screams of the terrified souls inside.
Where was the Humvee?
Then he saw it, racing toward them at an angle, bouncing wildly over the hardpan. Hollis and Olson were clinging to the vehicle’s roof. The big gun was depleted, all its ammo spent. The virals would be all over them any second.
Peter leaned out the door. “Bring it closer!”
Sara gunned the engine, drawing alongside. Hollis was the first to grab the ladder, then Olson. Peter pulled them through into the cab and called down, “Alicia, you go!”
“What about Sara?”
The Humvee was drifting away again, Sara fighting to keep them close without colliding. Peter heard a crash as the door of the last boxcar was ripped away, tumbling end over end into the receding darkness.
“I’ll get her! Just grab the ladder!”
Alicia jumped from the roof of the Humvee, hurling her body across the gap. But the distance was suddenly too great; in his mind Peter saw her falling, her hands grabbing at nothing, her body tumbling into the crushing rush of space between the vehicles. But then she had done it; her hands had found the ladder, Alicia was climbing hand over hand up the train. When her feet reached the bottom rung, she turned, stretching her body into the gap.
Sara was gripping the wheel with one hand; with the other she was frantically trying to wedge a rifle into place to brace the gas pedal.
“It won’t stay!”
“Forget it, I’ll grab you!” Alicia called. “Just open the door and take my hand!”
“It won’t work!”
Suddenly Sara gunned the motor. The Humvee shot forward, pulling ahead of the train. Sara was on the edge of the tracks now. The driver’s door swung open. Then she hit the brakes.
The edge of the train’s plow caught the door and sheared it off like
