The low thunder of heavy guns, the kind found on battleships, beats like a drum. I try to trace the missiles, reaching across the distance to decipher their trajectory. It’s too far, but I can guess. I’m Silver. I know how we think.

“Form a shield!” I shout to the Samos magnetrons, pulling upon the metal from our boats and weapons.

Ptolemus follows my lead, knitting together a steel wall as quickly as he can. The whistle of artillery grows closer and I look up, squinting through the haze. With a snap, I rip the goggles off my face to see an arc of smoke looping overhead.

The first missile explodes fifty yards ahead, pulverizing a section of the seawall, turning friend and foe to gray or pink mist in equal measure. Only the oblivions survive, some naked, their armor and uniforms charred right off their bodies. We cower behind our steel, weathering the blast as it pulses forward.

The smoke stings, acrid and poisoned with bone dust.

We won’t survive a direct hit like that. Not with what we have here. We can deflect the missiles as best we can, but it’s only a matter of time before one of them catches us. “Get off the wall,” I force out, tasting blood. “Into the fort.”

All to plan.

Get the battleships to open up, pummel their own walls. Keep the heavy fire on the fort, not the city or the Air Fleet.

That’s what Cal said they would do, and somehow the idiots are doing it.

Another round hits, cracking stone, as we grapple down the seawall, our ranks bleeding into Patriot. I look back, counting as quickly as I can. Maybe sixty of us made it in, down from our original strike group of seventy-five souls. Seventy-five deadly Silvers and battle-hardened Reds, their guns lethal and precise.

But their fire is reserved for Silvers. I notice they don’t bother with the soldiers in rusty red uniforms, the many conscripted assigned to the Patriot garrison. Some of those Reds follow their officers, running out to fight our ranks as we push on. Fewer than expected, though. As General Farley assured us, the word went out through her channels. The Reds of the city have been warned. When the assault comes, turn. Run. Or fight with us if you can.

Many do, joining our train of death.

Thunderheads pulse above, turning the sky black. Their lightning is unpredictable, less powerful than Mare’s. But a symbol all the same.

Enemy soldiers look up as we approach, the Silvers eyeing what can only be the work of the lightning girl.

She isn’t here, you idiots, I sneer in my head. Cowards, afraid of a bit of flashing light.

The interior fort is an experiment in chaos. By now Cal will have begun his own assault, marching his battalion up and out of the tunnel system Harbor Bay is built on. It is an old city, well preserved through the ages, with deep and twisting roots. The Scarlet Guard knows them all.

We make it to the central byway of the fort, moving quickly and without pattern. Leading the battleship fire, letting it follow and destroy. Keeping the worst weaponry from the city itself. Cal is so preoccupied with protecting innocents, probably just to show Mare he can. Hanging me out to dry in the process.

I cut through another wave of combatants, using a combination of bullets and blades to level the men and women in front of me. Their faces are shadows to me, inhuman. Unworthy of memory. It’s the only way to do this properly.

The whine and thrum of artillery become a familiar rhythm. I duck for cover as easily as I fight, moving in time with the noise. Smoke and ash swirl with the fog, leaving everyone blind. The Patriot garrison is hopelessly adrift. They don’t have a plan for this kind of attack. We certainly do.

My first burst of fear comes when I realize Ptolemus is no longer at my side, hemmed in by our protective circle of cousins. I glance at each of them, searching familiar faces of pale skin and silver hair. He isn’t here.

“Tolly!” I hear myself scream as another missile blasts, closer this time.

I crouch and brace, letting the concussive wave pass over me. Rubble breaks against my armor, coating my left side with dust. Blinking, I stand before the rest, whirling around. On the hunt. Terror claws up my spine, leaving icy, open wounds.

“PTOLEMUS!”

Whatever focus I had before slips through my grasp and everything splinters. The world spins. Where is my brother, where is he, did we leave him behind, did he push on, is he hurt, is he dying, is he dead—

The pop of gunfire snaps too close, a grim reminder. I whirl against our tide of soldiers. One of them knocks into me, her shoulder slamming mine, and I stumble. Gasping, I throw out my senses, reaching with my ability. Trying to locate that disk of copper. That tiny nub of pale orange metal, a different weight, a different feel. I come back empty. Nothing.

I told him we would be safe, even on the front lines of battle. Father would not waste us. Father would not let us go anywhere that might jeopardize his legacy. I suck down a poisoned breath, still scanning the silhouettes around me as the ash falls like summer snow. It coats our uniforms, no matter the color. We all start to look the same.

Even if Father doesn’t love us the way he should, he still values us. He wouldn’t trade our lives like this. Wouldn’t let us die for his crown.

But here we are.

Tears prick my eyes. From the ash, I tell myself. The sting of smoke.

Suddenly the copper rings on the edge of my perception, so small I almost miss it. My neck snaps with force as I turn, hunting for my brother. Without thought, I shove a few soldiers out of my way, vaulting through the swarm of battle. I duck under the arm of an approaching strongarm, tossing a bullet his way as I go. I feel it punch through his neck, a clean through-and-through. He drops behind me, clawing at his open jugular.

Every step brings new shapes into focus. The streets of Fort Patriot, meticulously organized in a grid, are easy to navigate. I hang my closest right, a hound sniffing out a bone.

Above me, walkways connect the various buildings. Soldiers in rusty uniforms charge back and forth, guns at the ready. I raise my forearm, shielding myself from the accompanying volley of gunfire. Red soldiers all, attacking from a safe distance. I let the bullets drop, flattened and useless. No use wasting my energy trying to kill them.

Ptolemus comes into view around the corner, sprinting, blissfully whole. I almost drop in relief. Smoke spirals behind him, evidence of more artillery fire. Missiles whistle overhead again, before exploding with resounding rumbles.

“What were you doing, you idiot?” I shout, skidding to a halt.

“Don’t stop—run!” he screams, catching me under the arm. I’m almost yanked off my feet by the force.

I know better than to argue when my brother is so incredibly terrified. All I can do is get my feet under myself, reorient, and sprint as fast as I can, keeping pace at his side.

“The seawall,” he forces out between pants of exertion.

It isn’t difficult to connect the dots.

I make the terrible mistake of looking back over my shoulder. Through the smoke, the fog, the thunder breaking overhead. To the cracks in the wall as they spread, pieces of stone as they crumble. The wall of water forcing itself up and over and in.

Standing over it, poised on a balcony, is the person controlling it all, her arms wide, her armor so deeply blue it could be black.

Iris Cygnet watches us run.

A swoop of panic nearly roots me to the spot, but Tolly drags me on, his hand wrapped around my bicep in a painfully tight grip. We skid out, back into the main street, chasing after our battalion only to find the lower levels of the fort deserted. Our soldiers are forward, and the rest, the enemies—they are up. Climbing into the buildings, standing on rooftops, clinging to the high ground with their weapons ready. No use trying to get to high ground of our own. All there is now is to get out.
