hour.…No, don’t go out yet. The way the beasts are running around they should die of heatstroke pretty quick. When they fall off the roof, you go.”

The rock demons followed Rachel twelve kilometers downslope before anything distracted them.

The howler was riding higher now, but Rachel wasn’t out of trouble. The emergency override locked the vents closed. If she turned it off the power would drop, and so would the howler. She was steering with her weight alone. Her speed would last as long as she was going down. She had almost run out of mountain. The slope leveled off as it approached the river.

The vicious pegasus-type birds had disappeared. The rolling mountainsides covered with feathery wheat were now covered with stubble, stubble with a hint of motion in it, dark flecks that showed and were gone. Millions of mice, maybe?

Whatever: they were meat. The demons scattered in twelve directions across the stubble, their big heads snapping, snapping. Rachel leaned forward across her windscreen to get more speed. Behind her, three rock demons converged on a golden Roman shield…on a mock-turtle that had been hidden by feather-wheat and was now quite visible and helpless. The demons turned it over and ripped it apart and ate and moved on.

The howler slid across the shore and onto flowing water.

Each patch of scarlet scum had sprouted a great green blossom. Rachel steered between the stalks by body english. She was losing speed, but the shore was well behind her now.

And all twelve rock demons zipped downhill across the stubble and into the water. Rachel held her breath. Could they swim? They were under water, drinking or dispersing heat or both. Now they arched upward to reach the air.

The howler coasted to a stop in midstream.

Rachel nerved herself to switch off the override. The howler dropped, and hovered in a dimple of water, churning a fine mist that rapidly left Rachel dripping wet. She waited. Come what may, at least the batteries were recharging. Give her time and she’d have a howler that could steer and fly.

The heatward shore was black with a million mouse-sized beasties. They’d cleaned the field of feather-wheat; but what did they think they were doing now? Watching Rachel? The rock demons noticed. They waded clumsily out of the water and, once on land, blurred into motion. The shore churned with six-legged white marauders and tiny black prey.

It seemed the fates had given Rachel a break. The water seemed quite empty but for the scarlet scum and its huge blossoms. No telling what might be hugging the bottom while the flare passed. Rachel could wait too. The coldward shore looked safe enough…though it had changed. Before the flare, it had been one continuous carpet of chrome yellow bushes. The bushes were still there, but topped now with a continuous sheet of silver blossoms. The clouds of insects swarmed still, though they might be different insects.

Upstream, something was walking toward her on stilts. It came at its own good time, stopping frequently. Rachel kept her eye on it while she tried the intercom.

She got static on all bands. Mountains blocked her from the expedition; other mountains blocked her from Touchdown City. The one sender that could reach Morven in orbit was on a crawler. Dammit. She never noticed the glowing pinpoint that meant Bronze Legs had called. It was too dim.

Onshore, two of the rock demons were mating head-to-tail.

The thing upstream seemed to be a great silver Daddy-long-legs. Its legs were slender and almost long enough to bridge the river; its torso proportionately tiny. It paused every so often to reach deep into the water with the thumbless hands on its front legs. The hands were stubby, armored in chitin, startlingly quick. They dipped, they rose at once with something that struggled, they conveyed the prey to its mouth. Its head was wide and flat, like a clam with bulging eyes. It stepped delicately downstream, with all the time in the world…and it was bigger than Rachel had realized, and faster.

So much for her rest break. She opened the rear vent. The howler slid across the river and onto shore, and stopped, nudging the bushes.

The Daddy-long-legs was following her. Ten of the dozen rock demons were wading across. As the bottom dipped the six-legged beasts rose to balance on four legs, then two. As bipeds they were impressively stable. Maybe their tails trailed in the mud bottom to serve as anchors. And the mice were coming too. Thousands of them, swimming in a black carpet among the patches of scum.

Rachel used the override for fifteen seconds. It was enough to put her above the silver-topped bushes. The lily-pad-shaped silver blossoms bowed beneath the air blast, but the ground effect held her. She wasn’t making any great speed. Bugs swarmed around her. Sticky filaments shot from between the wide silver lily pads, and sometimes found bugs, and sometimes struck the fans or the ground-effect skirt.

She looked for the place that had been cleared for a fux encampment. Deadeye would be there, a feisty male biped guarding his nest, if Deadeye still lived. She couldn’t find the gap in the bushes. It struck her that that was good luck for Deadeye, considering what was following her.

But she was lonely, and scared.

The Daddy-long-legs stepped delicately among the bushes. Bushes rustled to show where ten rock demons streaked after her, veering to snatch a meal from whatever was under the blossoms, then resuming course. Of the plant-eating not-mice there was no sign, except that here and there a bush had collapsed behind her.

But they were all falling behind as the fuel cells poured power into the howler’s batteries.

Rachel oriented herself by Argo and the Jet Stream and headed south and coldward. She was very tired. The land was darkening, reddening…and it came to her that the flare was dying.

The flare was dying. The goggles let Bronze Legs look directly at the suns, now, to see the red arc enclosing the bright point of Helle. A bubble
