Iron Moon Command

The Grey is dying, and the chain has chosen a human.

Vance Corry is a signaller — copper wire and lamp-code, acid-scarred hands, six years of hauling cable under fire for a wolf battalion that rates humans barely above pack mules. He has never carried a fang and never wanted the pack-mind. But at Harrow Ford, with the Rabid herds coming over the ice and the battalion coming apart band by band, Alpha Sable of the Iron Moon rolls her dying claw-rings against his open palm and speaks the old rite: Chain of my chain. Throat of my throat. Bear what I bear and break when I break.

The chain-mark closes on his wrist like a brand. In his bones a cold compass snaps north, and nine hundred wolf-heartbeats are suddenly his to hold.

Her last order is simple and impossible. Bring my battalion inside the Wall in companies, not in rags. Count them. Count them living or count them dead, but every one of them counted, or this command is a lie with a human in it.

The battalion does not want him. Fen, the enforcer of Anvil Company, rises in the old words and enters the blood-challenge: when the Grey dies, he will spill the lie from the human's wrist or wear his head in the trace-chain. Colonel Rurik Dane rides up from Fort Harren under inspecting colors with a hanging in mind. And somewhere inside the garrison of Caerholt, a traitor is selling Ash Company's route to the enemy, one countersigned wagon at a time.

Beyond the wall, General Korr's Blackfur Legion drives the ashvein-mad toward the Iron Wall, herding them to a slaughterhouse with good manners. Vance fights the way he mends wire: by arithmetic, by lamp-light, by the compass in his wrist that tells him where every wolf stands and every line is about to break. One unshifted picket gap costs a dead wolf whose name he writes into the Grey's journal with the true numbers. It will not happen twice.

Then the war turns south, and the plague turns with it. In the drowned country — beehive kilns black with standing water, herds standing hip-deep and facing home — his surgeon opens a stallion's skull and finds the truth in the marrow. The Rabid are not sick. They are leashed. Someone had the drowned kilns reopened twenty years ago and stitched a command word into twelve hundred brains, and the man who keeps that word is coming north in white gloves and perfect manners to collect the wall.

To free the herds, Vance must take the chain to full depth, where the imprint finishes on a human throat with three outcomes and none of them are good. To keep his wolves, he must out-argue an inspector, out-count a general, and out-signal an Order that has been reading the March for two hundred years.

A human signaller. A wolf army that has never once obeyed one. A wall that can no longer be held by teeth alone.

The signal is going up the wire. The Iron Moon is about to answer.
