To my chagrin, Cal ignores me, and pries away the melted bar of the cell. His back spikes with flame, protecting himself from any weapon the other magnetron can throw at him. I can barely see him through the twists of fire, but I see enough. He’s horribly angry, and it’s no mystery why. He hates me for killing those Silvers—for doing what he can’t. I never thought I’d see the day when Cal, the soldier, the warrior, would fear to act. Now he focuses on opening as many cells as he can, ignoring my pleas for help, forcing me to fight alone.

“Cameron, drop him!” I yell, glancing up at my unlikely ally.

“With pleasure,” she snarls, extending a hand to the magnetron attacking me. He stumbles, but doesn’t fall. She’s weakening.

I scramble along the cells, toes almost slipping, fingers straining with every passing second. I’m a runner, not a climber, and I almost can’t fight this way. Almost. A sharp, diamond-shaped razor grazes my cheek, opening a wound across my face. Another cuts my palm. When I grab the next bar, my grip is weak, slipping through my own blood. I fall the last six or seven feet, landing hard in the bowels of the block. For a second, I can’t breathe, and I open my eyes to see a gigantic spike whistling at my head. I roll, dodging the killing blow. Another and another rain down, and I have to zigzag across the floor to stay alive. “Cal!” I shout again, more angry than afraid.

The next spike melts before it reaches me, but the iron globs splatter too close, burning across my back. A scream escapes me as the fabric of my suit melts into my scars. It’s nearly the worst pain I’ve ever felt, second only to the sounder and the excruciating coma that followed. My knees slam into the ground, sending jolts of agony up my legs.

Pain, it seems, is another one of my triggers.

The skylight high above us shatters, and a bolt of lightning explodes down to me. For a split second, it’s like a purple tree has grown up from the sublevel, branching and veining through the open atrium of Block G. It catches one of the magnetrons, and she doesn’t even have time to scream. The other, the last guard, is all but finished, reduced to cowering on his last sheet of metal, curled up against Cameron’s hammering will.

“Julian!” I shout once the air clears. “Sara!”

Cal jumps down at the other end of the floor, his hands cupped around his mouth. He refuses to look at me, searching the cells instead. “Uncle Julian!” he roars.

“I’ll just wait up here,” Cameron says, watching us from the open doorway at the top level. Her legs dangle. She even has the gall to whistle, eyeing the last magnetron as he moans.

Block G is just as dank as the newblood D, and, thanks to me, half-destroyed. A hole smokes in the center of the floor, the only remnants of my massive bolt. From what I can see, the bottom cells are almost pitch-black, but they’re all full. A few prisoners have stumbled to their bars, coming to look at the commotion. How many faces will I recognize? But they’re too drawn, too gaunt, their skin almost blue with fear, hunger, and cold. I doubt I’d recognize even Cal after a few weeks down here. I expected more for the Silvers, but I guess political prisoners are just as dangerous as secret, mutated ones.

“Here,” a voice croaks.

I nearly trip over a magnetron body, running even though the burns on my back protest with every step. Cal meets me there, his hands on fire, ready to melt the bars, to save his uncle, to make amends for some of his sins.

The man in the cell looks weak, as old and frail as his beloved books. His skin has gone white, his remaining hair thin, and the lines on his face have multiplied and deepened. I think he’s even missing teeth. But there’s no mistaking his familiar brown eyes and the spark of intelligence still burning deep inside. Julian.

I can’t get to him fast enough, and hover almost too close to the melting metal. Julian. Julian. Julian. My teacher, my friend. The first bar buckles and Cal wrenches it away, creating a space big enough for me to slip through. I barely notice the suffocating pressure of Silent Stone and focus instead on pulling Julian to his feet. He feels brittle, as if his bones might snap, and for a moment, I wonder if he’ll get out of this alive. Then his grip on me tightens and his brow furrows in concentration.

“Bring me to that guard,” he growls, betraying some of his old spirit. “And get Sara out.”

“Of course. We’re here for her too.” I put his arm over my shoulder, helping him walk. Though he’s much taller than me, he feels shockingly light. “We’re here for everyone.”

When we get him outside the cell, Julian stumbles, but keeps his footing. “Cal,” he mutters, reaching for his nephew. He takes his face in his hands and studies the exiled prince like he would an old book. “Things were done, weren’t they?”

“Yes, they were,” Cal growls. He doesn’t look my way.

The cells changed what Julian looks like, but not who he is. He nods in understanding, looking very solemn. It comforts Cal in no small way. “Such thoughts have no place here and now. But after.”

“After,” Cal repeats. Finally, he turns his blazing eyes on me. I feel burned by them. “After.”

“Come, Mare, help me to that festering lump.” Julian points to the guard on the floor, unconscious but still living. “Let’s see if I’m not totally useless.”

I do as I’m told, acting as Julian’s crutch as he limps to the fallen officer. Meanwhile, Cal gets to work on Sara’s cell, located across the floor from Julian. Within sight and earshot, but too far away to touch. Another small torture that they had to withstand.

I’ve seen Julian do this before, but never with such effort or pain. His fingers shake as he pries open one of the officer’s eyes, and he swallows many times, trying to call forth the voice that he needs. The song.

“It’s all right, Julian, we can find another way—”

“Another way will get us killed, Mare. Have I taught you nothing at all?”

Despite the situation, I have to smile. I fight the urge to hug him, and try to hide my grin.

Finally, Julian exhales, eyes half-shut. Veins stand out in his neck. Then his eyes snap open, wide and clear. “Wake,” he says in a voice more beautiful than sunset. Beneath us, the officer does as he’s told, his other eye drifting open. “Open the cells. All of them.” A twisting shriek echoes up and down the block as the bars of every single cell bow open in unison. “Build the stairs and walks. Connect everything.” Clang. Clang. Clang. Every shred of metal, the daggers, the electrocuted shards, even the melted drops, flatten and reform, banging together in succession. “Walk with us.” Julian’s voice quivers in the last order, but the magnetron obeys, if a little slowly.

“You’re lucky you came today, Mare,” Julian says as I help him straighten. “They walked us yesterday. We are not so weak as we usually are.”

I debate telling Julian about Jon, his ability, his advice. Julian will love hearing about him. After, I tell myself. After.

For the first time, I have hope.

There will be an after.

Chaos descends on Corros. Gunfire echoes in every corridor, behind every door. The ragged band of Silvers follows us weakly, but a few have the strength to complain. I don’t trust them at all, and almost walk backward to keep watch. Many branch off, slipping around corners, eager to be rid of this place. Others go deeper into the prison, looking for revenge. A few stay with us, their eyes downcast, ashamed to follow the lightning girl. But still they follow. And they fight as best they can. It’s like dropping a stone in a still pond. The ripples start small, but they certainly grow. Each block falls more easily than the last, until the magnetrons inside must run from us. The Silvers kill more than I do, falling on their betrayers like hungry wolves. But even this cannot last. When a Lerolan oblivion blasts away a stone barrier, opening Block J to us, the debris falls not down—but up. And before I understand what’s happening, I’m being sucked into a whirlwind of smoke, shards, and unearthly whispers.
