The rhythmic noise got deep into Thuy's head; for some reason she recalled her mother's fear that an electric fan in her bedroom at night might chop up her dreams.

Lo and behold, the harp was ripping apart the subbies' root hairs! The illusory Egyptian-style props disappeared.

The unadorned Subdee world was an endless, dry desert, with the parched yellow ground blending into clouds of dust in the middle distance. The disk of a bloated red sun was faintly visible through the ochre sky. Innumerable fat plants were scattered across the dry plain, mobile succulents with snaky, hungry roots like writhing tentacles. The subbie plant-creatures ranged from being waist-high to taller than Thuy. Each of them had two or three meaty leaves, like "living rocks" or lithops plants. All of the subbie-plants bore thorny structures that could tear a person's flesh.

Two of the subbies kept pulling their roots out of the ground, inching to the left, inching to the right, then burying their roots again. They were the dancer subbies who'd played at being jackal-women. The four subbies who'd resembled bird-headed men were plants as well, but they bore hydrogen bladders that allowed them to hang in the air. Fretfully they circled Thuy, whipping their roots in the air.

As for the oversized lithops who'd presented himself as a sacred scarab, he still looked a bit like a beetle, with two fat leaves stuck together for a body, and roots for legs and feelers. A hollow, sharp-tipped feeder root jutted from his front end, framed by rigid growths. The feeder root looked entirely capable of draining Thuy's blood.

Although the harp's insistent buzz had driven back the subbies, the sound was fading now. So once again the subbies closed in. Thuy kicked at the ground, wondering how to break back through the Planck frontier. The sandy soil was translucent, as if made of glass beads, with slowly swirling streaks that betokened the seething of the quantum foam. Thuy kicked harder, then bent down and butted the dirt with her head. But it wasn't opening up for her.

A sharp pain pierced her calf; the beetle plant had ripped a gash. A hovering bird-man plant shot a vicious feeder tube past her. Thuy felt the tingle of root hairs puncturing her skull, and once again a phantom Egyptian temple began to form. Meanwhile, the dancer plants had swathed the harp with writhing skeins of roots; the hairy tendrils were eating away the uncanny painting that adorned the soundbox. Perhaps it had been by the Hibrane Hieronymus Bosch?

Desperately, Thuy began flailing the harp strings. The sound came out as a series of sour warbles. Again the Egyptian scenery faded away, but on every side the persistent subbies were menacing Thuy with their spiked feeder tubes.

Thuy mustered all the magic she knew: she thought of Wheenk , Chu's Knot, and her love for Jayjay. She reached out for psychic contact with the harp; she plucked and strummed the strings, steeling herself against the creepy tingling, piling note upon note, playing her hopes and fears and pain. The sounds beat against each other; the very fabric of space began to shake.

Irregular circles of light and dark pulsed from the base of the harp. Flakes of paint showered from the soundbox. Thuy twanged the strings still more frantically, and now, yes, the ground irised open. She wrapped her arms around the magic harp and the two of them fell down, up, through the hole.

Once more she was hovering above a boundless foamy sea. As the hole in the ocean closed up, some faintly glowing lines came snaking through. Root hairs! Time to fly home. It required but the slightest touch of Thuy's will to set herself speeding low across the bubbling waves.

A minute passed, another, another. The harp was awkward and heavy in Thuy's arms, once again playing dumb. Was Thuy heading the right way? She pressed on.

It was hard to quantify the passage of time within this interbrane quantum level, but eventually Thuy became quite sure that she'd been flying far longer than on her initial jump from the Lobrane to the Hibrane. She changed course and flew some more-with still no sign of the homey Lobrane. She was lost.

What had Chu said? There's a lot of different directions in hyperspace . Hopelessly off course as Thuy was, the direction pointed by the Knot meant nothing now.

The subbies were still trailing her. She knew to dodge the root hairs they kept sending up like harpoons. The subbies wanted her to think they looked like bird-headed men, but Thuy could see they were fat-leaved plants with hydrogen bladders, waving their stubby roots. Greedy heartless pods.

Thuy was bone-weary, but still she clung to the silent harp. She wasn't going to be able to fly much longer. The subbies would draw her under and eat her. The Big Pig would release the nants. Jayjay was probably dead. Life was a hopeless mess.

And then Thuy heard Jayjay's voice, calling to her across the dimensions. His dear face led her home.

"Jayjay? This is real?"

Jayjay sat bolt upright. "Thuy? Oh thank god. I'm not dead, I'm not old, and you're here. I had this jitsy dream that lasted sixty years. The Big Pig's been mind-gaming me. I thought I died and went to look for you."

"Am I in time?"

"We're in synch again," said Jayjay, not immediately getting the point of her question. "Tick, tock. I love you, Thuy." The nanomachine goo was gone. Orphids outlined the walls and floor of the unlit cave. A few hundred tiny flying shoons were busy around the nantanium-walled nant farm that sat nestled, still intact, upon the shards of the plastic box that had been the Ark of the Nants. The fireflylike shoons were sending pulses of laser light into the nant farm, still tweaking the nant code. The orphidnet revealed a powerful-looking figure standing guard over the nant farm, a waist-high golem shoon with a smooth, stylized face and bell-bottom-shaped arms and legs.

"What time is it right now?" persisted Thuy. She wasn't online. The orphids were only just now landing on her.

"Um, quarter to midnight," said Jayjay, checking the little local network that the Pig was letting them see. His mind felt stiff and clunky in these confines. "The nants are still walled up. We have fifteen minutes."

"Hug me quick, Jayjay."

"Yes." Thuy was a black spot in the local orphidnet. As Jayjay reached for her in the velvety dark, he bumped into something

big and hollow. It made a resonant boinging sound.

"Don't knock over my magic harp," said Thuy.

"Thuy and the Beanstalk," said Jayjay. "You robbed the giant." He got his arms around her, and they kissed for a few minutes. Thuy smelled and felt and tasted as good as ever. The orphids had finished settling on her; he could see the sweet outlines of her face. They kissed some more. For now the Big Pig left them alone; she was preoccupied with the nant farm.

"You had a dream that lasted sixty years?" said Thuy presently.

"It damaged me," said Jayjay, cuddling Thuy. "I'm old. I'm incredibly grateful to have a twenty-four-year-old girlfriend. Tell me more about your Hibrane adventures. And your harp."

"The strings are jitsy," said Thuy. "And the harp is alive. She helped me escape these cannibal cactuses that live under the ocean that separates the branes. The subbies from Subdee. They scratched my leg. They ate the painting off the harp." Thuy paused and took a deep breath. So much to tell. "The way it started, Gladax was about to addle my brain. Ond, Chu and I stole the harp and ran away. Gladax could have caught us but-" Thuy paused, again mentally replaying the events.
