Snake closed the leather case and put on the new robes and headcloth Arevin’s people had given her. She was grateful to them for the clothes, at least, for the strong delicate material was excellent protection against the heat and sand and dust.

Merideth mounted, freed the stirrup, reached for Snake’s hand. But when Snake approached, the horse flared her nostrils and shied at the musky smell of serpents. Beneath Merideth’s gentle hands she stood still but did not calm. Snake swung up behind the saddle. The horse’s muscles bunched and the mare sprang into a gallop, splashing through the water. Spray touched Snake’s face and she tightened her legs against the mare’s damp flanks. The horse leaped across the shore and passed between delicate summertrees, shadows and delicate fronds flicking past, until suddenly the desert opened out to the horizon.

Snake held the case in her left hand; the right could not yet grasp tightly enough. Away from the fires and the water’s reflections, Snake could barely see. The black sand sucked up light and released it as heat. The mare galloped on. The intricate decorations on her bridle jingled faintly above the crunch of hooves in sand. Her sweat soaked into Snake’s pants, hot and sticky against her knees and thighs. Beyond the oasis and its protection of trees, Snake felt the sting of windblown sand. She let go of Merideth’s waist long enough to pull the end of her headcloth across her nose and mouth.

Soon the sand gave way to a slope of stones. The mare clambered up it, onto solid rock. Merideth held her to a walk. “It’s too dangerous to run. We’d be in a crevasse before we saw it.” Merideth’s voice was tense with urgency.

They moved perpendicular to great cracks and fissures where molten rock had flowed and separated and cooled to basalt. Grains of sand sighed across the barren, undulating surface. The mare’s iron shoes rang against it as if it were hollow. When she had to leap a chasm, the stone reverberated.

More then once Snake started to ask what had happened to Merideth’s friend, but she remained silent. The plain of stone forbade conversation, forbade concentration on anything but traversing it.

And Snake was afraid to ask, afraid to know.

The case lay heavy against her leg, rocking in rhythm to the mare’s long stride. Snake could feel Sand shifting inside his compartment; she hoped he would not rattle and frighten the horse again.

The lava flow did not appear on Snake’s map, which ended, to the south, at the oasis. The trade routes avoided the lava flows, for they were hard on people and animals alike. Snake wondered if they would reach their destination before morning. Here on the black rock the heat would build rapidly.

Finally the mare’s gait began to slow, despite Merideth’s constant urging.

The smoothly rocking pace across the wide stone river had lulled Snake almost to sleep. She jerked awake when the mare slid, pulling her haunches under her, scrabbling with her hooves, throwing the riders back, then forward, as they came down the long slope of lava. Snake clutched her bag and Merideth and clamped the horse between her knees.

The broken stone at the foot of the cliff thinned out, no longer holding them to a walk. Snake felt Merideth’s legs tighten against the mare, forcing the exhausted horse into a heavy canter. They were in a deep, narrow canyon, its high walls formed by two separate tongues of lava.

Spots of light hovered against ebony and for a moment Snake thought sleepily of fireflies. Then a horse neighed from a long distance and the lights leaped into perspective: the camp’s lanterns. Merideth leaned forward, speaking words of encouragement to the mare. The horse labored, struggling through the deep sand, stumbling once and throwing Snake hard against Merideth’s back. Jolted, Sand rattled. The hollow space around him amplified the sound. The mare bolted in terror. Merideth let her run, and when she finally slowed, foam dripping down her neck and blood spattering from her nostrils, Merideth forced her on.

The camp seemed to recede, miragelike. Every breath Snake took hurt her as if she were the mare. The horse floundered through deep sand like an exhausted swimmer, gasping at the height of every plunge.

They reached the tent. The mare staggered and stopped, spraddle-legged, head down. Snake slipped from her back, soaked with sweat, her own knees shaky. Merideth dismounted and led the way into the tent. The flaps were propped open, and the lanterns within suffused it with a pale blue glow.

The light inside seemed very bright. Merideth’s injured friend lay near the tent wall, her face flushed and sweat-shiny, her long curly brick-red hair loose and tangled. The thin cloth covering her was stained in dark patches, but with sweat, not blood. Her companion, sitting on the floor beside her, raised his head groggily. His pleasant, ugly face was set in lines of strain, heavy eyebrows drawn together over his small dark eyes. His shaggy brown hair was tousled and matted.

Merideth knelt beside him. “How is she?”

“She finally went to sleep. She’s been just the same. At least she doesn’t hurt…”

Merideth took the young man’s hand and bent to kiss the sleeping woman lightly. She did not stir. Snake put down the leather case and moved closer; Merideth and the young man looked at each other with blank expressions as they became aware of the exhaustion overtaking them. The young man suddenly leaned toward Merideth and they embraced, silently, close and long.

Merideth straightened, drawing back with reluctance. “Healer, these are my partners, Alex,” a nod toward the young man, “and Jesse.”

Snake took the sleeping woman’s wrist. Her pulse was light, slightly irregular. She had a deep bruise on her forehead, but neither pupil was dilated, so perhaps she was lucky and had only a mild concussion. Snake pulled aside the sheet. The bruises were those of a bad fall: point of shoulder, palm of hand, hip, knee.

“You said she went to sleep — has she been fully conscious since she fell?”

“She was unconscious when we found her but she came to.”

Snake nodded. There was a deep scrape down Jesse’s side and a bandage on her thigh. Snake pulled the cloth away as gently as possible, but the dressing stuck with dry blood.

Jesse did not move when Snake touched the long gash in her leg, not even as one shifts in sleep to avoid annoyance. She did not wake from pain. Snake stroked the bottom of her foot, with no result. The reflexes were gone.

“She fell off her horse,” Alex said.

“She never falls,” Merideth snapped. “The colt fell on her.”

Snake sought the courage that had seeped slowly away since Grass was killed. It seem irretrievable. She knew how Jesse was hurt; all that remained was to find out how badly. But she did not say anything. Resting one forearm on her knee, head down, Snake felt Jesse’s forehead. The tall woman was sweating coldly, still in shock.

If she has internal injuries, Snake thought, if she is dying…

Jesse turned her head away, moaning softly in her sleep.

She needs whatever help you can give her, Snake thought angrily. And the longer you swim in self-pity, the more likely you are to hurt her instead.

She felt as if two completely different people, neither of them herself, were holding a dialogue in her mind. She watched and waited and was vaguely grateful when the duty-bound self won the argument over the part of her that was afraid.

“I need help to turn her over,” she said.

Merideth at Jesse’s shoulders and Alex at her hips, they eased her up and held her on her side, following Snake’s instructions to keep from twisting her spine. A black bruise spread across the small of her back, radiating both ways from the vertebrae. Where the color was darkest, the bone was crushed.

The force of the fall had almost sheared the spine’s smooth column. Snake could feel shattered chips of bone that had been pushed out into muscle.
