rock. If Nish was up there, the breeze was blowing his scent away. She scrabbled up to the seventh level. Her fingers were aching and she’d broken most of her toenails. Ullii needed to rest but drove herself on; she had to know. The wall and the embrasure above her were steaming, and a trickle of smoke issued from a deep fissure to one side of it.
Ullii peered over the lip of the embrasure and was confronted by a network of hundreds of spears and blades of rock glass, arching up like scimitars from a hole in the centre of the floor. The room was full of them. A hole in the jumbled floor was blocked by congealed glass, still cracking as it cooled.
Now she smelt Nish, though it was a strange, baked odour, the arid smell of desiccated skin. Ullii felt for the knife in her pack but did not pull it out. It was enough to know it was there. A trail of smoke drifted across her face, burning the membranes in her nose. She breathed through her mouth, her eyes watering as she scanned the floor. There was no sign of him. She looked up through the network of glassy blades and there he was, his arms and legs wrapped desperately around the iron rods that supported the roof. He looked as if he could barely hang on.
Instinctively she bared her teeth, but the gesture faded as her eyes adjusted to the gloom. He was coated, no, crusted with smoke and soot. His hair and skin were black and the individual hairs of his beard stood out like bristles. Skin was flaking off his nose and lips, the whites of his eyes were like chips of marble on black velvet, and he was shaking so hard that his teeth clattered.
Nish licked cracked lips and Ullii saw blood on his tongue. She pulled herself up onto the sill of the embrasure, staring at him, overcome. Rage warred with a most desperate longing for him to put his strong arms around her and make everything all right.
Nish saw her and let go with one hand, reaching out. ‘Help me, Ullii.’
His agony showed in the crevices around his mouth, the shuddering of his arms, the staring eyes, but that was nothing to her own pain. He’d lost nothing; she had nothing left. He’d torn it all away.
‘Water,’ he croaked, tongue rasping over his lips. ‘Please.’
The begging made her think less of him. Nish had always been strong. Now he was weaker than her and she felt nothing but contempt. ‘Come down.’
‘The blades will cut me to ribbons.’
She hoped so. Ullii wanted to see his blood run free. ‘Jump!’
Nish considered all possible ways down, biting his sooty lip. ‘I can’t.’
Ullii had always resisted using her initiative. In the long years when the only thing she’d wanted had been her brother back, it had been easier to drift. Now the desire for retribution was so strong that it seared her.
She moved around to the next embrasure, out of sight from below. Taking her boots out of her pack, Ullii put them on then climbed onto the sill and hurled her pack up into the middle of the chamber. The fragile glass sang as it smashed and, with a tinkling roar, the central part of the network fell to the floor. She wove between the remaining spears, glass crunching under her soles, and eased her head over the sill on the yard side. Several guards had looked up at the sound, but only briefly. Pieces were falling off the tower all the time.
Nish was staring down at the gap. The pack had carved an elongated scar through the glass spears, though it wasn’t much wider than a human body.
‘Can you throw the pack again?’ he said.
It lay under a network of quivering spears, so precariously perched that a breath could have dislodged them. She shook her head.
Nish pulled himself along the supporting rods, choosing the spot carefully. He couldn’t drop – he had to throw himself through at just the right angle and, even had he been fit and strong, that would not have been easy. His hands were shaking. He rubbed his palms down his trousers, coating them with greasy soot. He tried to rub it off again but only smeared it everywhere. Nish gripped a rod, lowered himself until he was hanging full stretch, and began to sway back and forth.
