Alek's shoulder. "That sword is two centuries old! Your father - "
"Can't help us," Alek said. "Reload the machine guns in case those scouts come back."
Without waiting for a reply he pulled himself up and out.
Up top, branches slapped at his face, and the machine rocked beneath him like an unbroken horse. Klopp was doing his best serpentine. The hot metal of the engine casing burned Alek's fingers even through his piloting gloves.
The marker flare was stuck among the Stormwalker's exhaust pipes, hissing and spitting, driven brighter by the machine's speed. Red smoke trailed out, spreading as it rose into the brilliant sky.
Alek drew the saber and clutched it with one hand, holding the scabbard with the other. He raised the sword high, then brought the blade down hard.
The flare split open under his blow, but only blazed brighter, like a burning log jabbed with a poker.
Alek raised the sword again and saw flames running along his blade - the fire was clinging to the metal! He swallowed, wondering what would happen if the infernal substance were stuck to someone's skin.
"AN HEIRLOOM SAVES THE HEIR."
Lights flickered through the trees. Alek looked up and glimpsed the frigate in the distance, smoke pouring from her guns. As he knelt for a firmer handhold, the cannon's rumble followed at the tardy speed of sound.
Long seconds later the shells hit. The shock wave battered his ears, spraying dirt into his face and lifting the walker beneath him.
Alek felt its massive feet hit the ground again, the machine staggering like a newborn colt. He opened his eyes - just in time to duck beneath a tree branch whipping across the walker's head.
Now there was no sound except the ringing in his ears, and his eyes stung with debris and smoke. But he could feel Klopp righting the walker, regaining control.
The frigate would have their range now. Each time they fired, the shells would land closer.
Alek stooped again and raised the saber, hacking at the sticky flare, sending up sparks and angry gouts of smoke. Embers fell from the blade onto his uniform, burning into the leather piloting jacket like hot coals. He smelled his own hair singeing in the heat.
A volley of flares shot past, the retreating scouts taking one last shot at the Stormwalker. Alek ignored the near misses and kept battering at the flame.
Finally a big chunk came free, sticking to his saber like honey on a stick. He waved the blade back and forth in the wind, but that only drove the flare brighter.
Alek swore. The frigate's guns would be loaded again in another few seconds. There was only one thing to do.
He rose into a half crouch, one arm wrapped around an exhaust pipe.
"Sorry, Father," he whispered, and threw the ancient saber as hard as he could into the forest.
He kicked at the last few burning pieces clinging to the Stormwalker's armor, then crawled toward the open hatch.
"Klopp!" he shouted down. "Go straight ahead, as fast as you can!"
Alek glanced back before climbing inside. The ancient sword was still burning back among the trees, sending up red smoke. The gunners on the frigate would think that the Stormwalker had staggered to a halt, or fallen after that last barrage. Hopefully they'd pound the spot a few more times before sending the scouts back in to check.
And by that time the walker would be kilometers away.
As Alek's adrenaline faded, his body began to throb with pain. His hands and knees were bruised and burned, and the leather of his uniform smelled like scorched meat. He hoped Volger had something for burns along with his supply of family heirlooms and pointless secrets.
As Alek lowered himself into the hatchway, Volger's eyes widened, taking in his singed hair and smoldering uniform.
"Are you all right?"
"I'm fine," he said, collapsing into the commander's chair. "Just keep moving."
The mountains were rising taller in the viewport. The border couldn't be far now; the sky up ahead was empty of flares. Soon they'd been in friendly darkness again.
The frigate's guns rumbled again, but the shells hit far behind them, hardly breaking the Stormwalker's stride. The Germans were still firing at his father's sword.
Alek smiled - so much for their secret weapons.
He let his eyes close. After a month of running, finally he could rest. Maybe his life would begin to make sense again, once the Stormwalker had reached safety.
No more surprises for a while.
