What happened was that Harrowhark peeled off her gloves. Her hands were wrecked. The fingers were riddled with dirt and oozing cuts, and grit stuck in the wounds and beneath the messed-up nails. She dropped the gloves and wiggled her fingers in Gideon’s direction, and Gideon had a split second to realise that it was drillshaft grit, and that she was absolutely boned in all directions.
She charged. It was too late. Next to the drifts of dirt and stone that she had carefully kicked apart, skeletons burst out of the hard earth where they had been hastily interred. Hands erupted from little pockets in the ground, perfect, four-fingered and thumbed; Gideon, stupid with assumption, kicked them off and careened sideways. She ran. It didn’t matter: every five feet—every five goddamned feet—bones burst from the ground, grasping her boots, her ankles, her trousers. She staggered away, desperate to find the limits of the field: there were none. The floor of the drillshaft was erupting in fingers and wrists, waving gently, as though buffeted by the wind.
Gideon looked at Harrow. Harrow was breaking out in blood sweat, and her returned stare was calm and cold and assured.
