On the backs of many other horses rode skeletons human and non-human, and corpses of various ages. They were long dead of fear or hunger but still riding, held astride by their wind-dried hands. Some horses had many sets of finger-bones entwined in their manes; some carried arms b.u.mping from tangled hands, but the rest of the body had fallen away. They had abducted hundreds over the millennia.

The Gabbleratchet arced straight above me and plunged down vertically. White flashes in the seething storm were the teeth of those in the lead. The moonlight caught eyes and hooves in tiny pulses of reflection.

I had never seen anything fly vertically downward. It shouldn't be able to. It wasn't obeying any physical rules.

Cyan clung on. I wondered if she was still sane.

'Run!' shouted the Vermiform.

The Gabbleratchet's wild joy seized me. I wanted to chase and catch. I wanted the bursting pride of success, the thrill of killing! Their power transfixed me. I loved them! I hated them! I wanted to be one! I tasted blood in my mouth and I accepted it eagerly. My open smile became a snarl.

The dogs' muzzles salivated and their baying tongues curled. They were just above my head. I saw the undersides of the hooves striking down.

'Run!' screamed the Vermiform.

I jumped forward, sprinting at full pelt. The hunt's howling burst the air. Its gale blew my hair over my eyes and I glanced back, into the wind to clear it.

The lead beasts plunged into the ground behind me, and through it. The air and ground surface distorted out around them in a double ripple, as if it was gelatinous. The whole hunt trammelled straight down into the earth and forked sparks leapt up around it, crackling out among the gra.s.s. It was a solid crush of animal bodies and bone. I saw flashes of detail: fur between paw pads, dirty scapulae, suppurating viscera. The corpses the horses were carrying hit the ground and stayed on top. They broke up, some fell to dust and the creatures following went through them too. Cyan's horse was next; it plunged headfirst into the earth, throwing her against the ground hard. She lay lifeless. The stampede of manes and b.u.t.tocks continued through her. The column shrank; the last few plummeted at the ground and disappeared into it. Two final violet sparks sidewound across the plain, ceased. All was eerily quiet.

The Vermiform emerged beside me but its voices were awed. 'It'll take a minute to turn around. Quick!'

I ran to the area the Gabbleratchet had pa.s.sed through, expecting to see a dent in the frozen soil but not one of the gra.s.s blades had been bent; the only marks were my own footprints. The hairs on my arms stood up and the air smelt chemical, the same as when I once visited a peel tower that had been struck by lightning. There was no reek of corruption or animals, just the tang of spark-split air.

I turned Cyan over carefully. She had been flung against the ground at high speedfaster than I could flyand I thought she was dead, but she was breathing.

'I can't see any broken bones. Not that it matters if that thing's driven her mad.'

'Pick her up,' said the Vermiform.

I did so and she jolted awake, gasped, open-mouthed. 'Jant? What are you doing here?'

'Just keep still.' The Vermiform sprang up from under my feet and wrapped around us. More worms appeared, adding to the thread, beginning at my ankles then up to my waist, binding us tightly together.

Cyan waggled her head at the deserted tundra. She screamed, 'Do you have to follow me everywhere? Even into my nightmares?'

The worms nearest her face grouped together into a hand and slapped her.

Cyan spluttered, 'How dare!'

The hand slapped her again, harder.

'Thanks,' I said.

A horse burst from the ground, bent forelegs first. It pawed the gra.s.s without touching it. Its enormous rear hooves paced apart. Long hair feathered over them; its fetlock bones swayed as it put its weight on them and reared.

Cyan wailed, 'What does it want?'

Its fore hooves gouged the air, its long head turned from side to side. It couldn't understand what we were. It sensed us, with whatever senses it had, and it shrieked at us. It could not know its own power nor regulate its voice to our level. It gave us its full unearthly scream, right into my face.

The Vermiform tightened around my legs.

Its tongue curled, its jaw widened, it was bone; no tongue but the jaw dotted with holes for blood vessels and peaks for ligament connections. Its incisors clamped together, the veins appeared running into the bone, the muscles flowered and rotting horseflesh became a whole beast again. It turned its mad, rolling eye on me. Sparks crackled over us, tingling. Hounds and horses began springing up around us. No soil stuck to them; they had treated the earth as if it was another form of air.

The horse arched its neck. I looked up into the convoluted rolled cartilage in its nasal pa.s.sages. Its jutting nose bones thrust towards me, its jaw wide to bite my face. Slab teeth in living gums came down The Vermiform s.n.a.t.c.hed us away Its coils withdrew and dropped me on a hard surface. I sat up and crowed like a c.o.c.k, 'Hoo-hoo! That was a neat move, Worm-fest!'

Beside me Cyan crawled and spat. I helped her up: 'Are you all right?'

'Jant, what are you doing here?'

'I've come to rescue you.'

'Rescue me? Sod off! What just happened? Did you see those horse things?...Argh! Worms!...What the f.u.c.k are these worms?'

'Allow me to introduce you to the Vermiform,' I said. It was writhing around my feet in a shapeless ma.s.s. If it had been human, it would have been panting.

'We must keep going,' it chorused.

Cyan said, 'A horse was lying down and it seemed friendly. I climbed on its back. I didn't know that was going to happen...Oh, G.o.d, what is this place?'

A water drop landed on my head. Good question. I looked around and realised we were in a gigantic cavern, so vast I could not clearly see the other side.

The sound of a bustling market broke all around us. The stone walls rucked and soared up a hundred metres in the gloom, latticed with ledges from which bats dangled like plums. I gazed up to the roof, into vaults and rifts and wedding-cake tumbles of flowstone arching into darkness. The ceiling dazzled with circular gold and purple jewels, so lambent I was tempted to climb up and collect them until I realised they weren't gems embedded in the stone but water droplets hanging from it. They reflected the cool, blue light from the bulbous tails of Neon Bugs clinging to great trunks of suspended stalact.i.tes, bathing the whole chamber in their glow.

Market stalls were laid out in disorderly lines on the uneven floor, filling the cave, and up into a circular tunnel climbing slowly to the surface. Slake Cross town in all its entirety would fit into that pa.s.sage. Stalls tangled along both sides of it like a thread of commerce linking the cave to Epsilon city's immense market a kilometre or more above us.

'It's Epsilon bazaar!' I said. I'd known it extended underground but I had always turned down invitations to visit. I envisaged a dirty crawl with my head caught and pressed between two planes of rock, my feathers wet and muddied, and my knees popped from kneeling on stony nubs in a stinking stream pa.s.sage all the way. But this was wonderful!

At the distant end of the tunnel its entrance shone with white sunlight like a disc. Shafts of light angled in, picking out a faint haze in the air. Reflections arced the tunnel walls, showing their smooth and even bore.

I began, 'Well, Cyan, this'

The Vermiform seethed urgently. 'Explain when we have more time! The Gabbleratchet could be here any second!'

'What?'

'It could be chasing us. If it can still sense us, it will pursue us.'

Cyan said, 'This is weird. In dreams you're not normally able to choose what you say.' She crawled to her feet and wandered off between the stalls.

The Vermiform heaved limply. 'Come back!'

Cyan was looking at the gley men browsing in the aisles. Gley men are completely blind, just a plate of smooth bone where their eyes should be. They feel their way with very long, thin fingers like antennae, touching, touching, searching. They are naked and hairless with milky, translucent, waterproof skin; but underneath it is another skin covered with thick fur, to keep them warm in the deep abyss. You can see through their upper skin to the fur layer pressing and wiping against it.

Cyan didn't seem as repelled by them as I was. She seemed entranced. One of them, by a refreshment stand, was picking cave ferns off the wall and putting them in sandwiches. He had beer bottles, brown and frothy, labelled 'sump water'. He sold white mousse made from the twiggy foam that clings to the roofs of flooded pa.s.sages. He had boxes of immature stalagmite b.u.mps that looked like fried eggs, breccia cake, talus cones, and crunchy tufa toffee.

Cyan paused at a jewellery stall and examined the cave pearls for sale. She put on a necklace made from broken straw stalact.i.tes and looked at her reflection in the mirror-polished sh.e.l.l of a moleuskone of the metre-long sh.e.l.lfish that burrow far underground.

She didn't know that, as a visitor to the s.h.i.+ft, she could project herself as any image she wanted, so she appeared the way she imagined herself. Like most female s.h.i.+ft tourists Cyan's self-image was nothing like her real body. She was a bit taller, more muscular and plumper, and she wore casual clothes. She looked like a young, unattached fyrd recruit spending her day off in any Hacilith bar. She was slightly less pretty here than in the Fourlands; I suppose that meant she lacked confidence in her looks.

For once, I couldn't alter my appearance. I was here in the body and I planned to take it home intact.

Some stalls sold stencils and crayons for cave paintings. Some displayed everyday objects that 'petrifying water' had turned into stone. Mice with three legs (called trice) ran under the rows and cats very good at catching trice (called trousers) ran after them.

Neon Bugs illuminated beautiful constructions of silk. Replete Spiders hung from the ceiling on spindly, hairless legs, their huge, round abdomens full of treacly slime. It dripped, now and then, on the awnings of the stalls and the tops of our heads. The noisome things lived suspended all the time, and other bugs and centipedes as long as my arm swarmed over the cave walls to bring them morsels and feed them in return for the taste of the sweet gunge they exuded.

The smell of wet pebbles rose from the cavern floor, which descended in a series of dented ripplestone steps to a pool so neatly circular it looked like a hand basin. A waterfall cascaded down a slippery chute, gus.h.i.+ng into it. Its roar echoed to us across the immense chamber as a quiet susurration.

Naked gley children were sliding down the chute and splas.h.i.+ng into the water where Living Fossil fish swam; the play of their luminous eyes lit up the pool. It was screened by thick, lumpy tallow-yellow stalact.i.tes so long they reached the ground and were creeping out over it like wax over a candleholder. Between them chambers and pa.s.sages led off, descending in different directions into the depths. Most were natural but some were like mine shafts, with timber props and iron rails.

Tortuoise with huge sh.e.l.ls crawled frustratingly slowly up and down between the stalls, towing baskets on wheels. There were Silvans, child-shaped shadows who live only in the shade of cave mouths and tree-throws in the forest. At the furthest end of the cavern, where the subterranean denizens who prefer to stay away from the light shop and sell their wares, hibernating Cave Elephants had worn hollows in the velvet sediment.

'Call her back!' the Vermiform chorused. 'The Gabbleratchet could be here any second!'

I glanced at the cave mouth.

The Vermiform said, 'It doesn't need an entrance. It can go anywhere! It can go places you can't, where the atmosphere is poisonous: hydrogen, phosphorus, baked beans. You saw that solid rock is nothing to it. It can run straight through a planet without noticing.'

A big, lumpen Vadose was standing by a stall. Cyan realised that the man was made of clay. She sank her fingers into his thigh, pulled out a handful and started moulding it into a ball. The Vadose turned round. 'Excuse me, would you return that, please?'

'It's my dream and I can do what I want!'

'Dream?' articulated the Vadose. 'I a.s.sure you, poppet, this is no oneiric episode.'

The ball of clay in Cyan's hands puffed up into a tiny version of the Vadoseit t.i.ttered and waved at her. She yelped and dropped it. It ran on little feet to one of the Vadose's thick legs and merged smoothly with it. Cyan slapped his round belly, leaving a palm imprint.

He cried out bashfully and caught the attention of a Doggerel guard stalking past. It was a big bloodhound, bipedal on its hock-kneed back legs, wearing a constable's coat and the helmet of a market guard, black with a gold spike on top. The chin strap was lost in its drooping jowls. It rhymed: 'Shall I remove this silly la.s.s Who seems to be doing no sort of good?

In fact, you seem in some impa.s.se.'

The Vadose said, 'Yes, if you would.'

It placed its paw on Cyan's shoulder but she wasn't perturbed. She gave it a kick. Its hackles raised; it picked her up, tucked her under one arm and carried her to us. It set Cyan down in front of me: 'Here is your rowdy friend, Please keep her close.

Otherwise she may offend One more dangerous than Vadose.'

'Thanks,' I said.

'Talk in rhyme All the time,' insisted the Doggerel.

'First we are chased, then we are irritated,' the Vermiform complained.

'No, wait,' I said. 'I can do it...Thanks for being so lenient For my friend is no deviant She's a tourist here for the first time From now on she'll behave just fine.'

The Doggerel sn.i.g.g.e.red. 'Only a tourist and she looks so boring?

I'll leave in case she has me snoring.' It strode away with dignity, st.u.r.dy tail waving.

Cyan said, 'If this is a jook dream I'm going to do it all the time.' She set off towards the pool but the Vermiform snared her round the waist. She beat her fists at the worms reeling her in. 'Hey! Get off me!'

A small black puppy was trailing her. When she stopped, it sat down on its haunches and looked at her intently. It had pointed ears and alert, intelligent eyes. 'It's following me,' she said. 'It's cute. Makes a change from everything else in here.'

'It's just a Yirn Hound,' the Vermiform said dismissively and pushed it out of the way. It took a couple of steps to the side, resumed staring at Cyan.

'Can I pick it up?' she asked, and as she was speaking another dog padded towards her from under the nearest stall. It sat down and regarded her. She looked puzzled. Another two followed it, cl.u.s.tered close and stared up plaintively. Three more materialised from behind the corner of the next row and joined them.

The Vermiform's surface rippled in a sigh. 'They're desire made manifest. For every want or desire that a young woman has, a Yirn Hound pops into existence. If you stay in this world you won't be able to get rid of them. They will follow you around forever, watching you. Most girls grow accustomed to them, but otherwise Yirn Hounds drive them mad, because until you grow old they'll do nothing but stare at you. You could kill them, but more will appear to fill the s.p.a.ce.'

At least twenty little terriers had arrived while the Vermiform was talking. They sat in a rough circle around Cyan's feet and continued to regard her.

'Well, I like them,' she said, bent down to the nearest one and caressed its ears. It allowed itself to be stroked and waggled its head with pleasure. Their crowd thickened, but I couldn't tell where they were coming fromjust trotting in from nowhere and taking their places at the edge of the pack.

Their inevitable steady increase repulsed me. I said, 'G.o.d, girl, you have a lot of wants.'

'Compared to you? I bet you'd be buried in a pile by now!'

Sparks began to crackle in the tunnels at the far end. I caught a glimpse of the Gabbleratchet thundering in their depths. It more than filled every pa.s.sage and morphing beasts charged half-in, half-out of the bedrock. Their backs and the tips of their ears projected from the floors: for them, the rock didn't exist. Skeleton horses, rotting horses, horses glowing with rude health reached the tunnel mouths. Paws and pasterns projected from the wallthey burst out! The front of the screeching column came down the cavern in a red and black wave.

'The 'Ratchet!'

I couldn't look away. Their screaming was so deafening Cyan and I clamped our hands to our ears. They tore everybody in their path to shredsobliterated the Neon Bugs on the walls as they pa.s.sed, and the lights went out.

The Vermiform wrenched us backwards Bright sunlight burst upon us. I squeezed my eyes shut, blinked, and tasted clean, fresh air. A warm breeze buffed my skin...We were on a beach. Cyan yelled, disorientated.

'Precambria!' said the Vermiform. We tumbled out of its grasp onto the yielding sand.

'Good s.h.i.+ft,' I said.

'The Gabbleratchet is chasing us!' It quivered. 'We doubt we have thrown it off. We will take you on again.' It pooled down around us, its worms moving fitfully, trying to summon up the energy.

A barren spit curved away into the distance. The aquamarine sea washed on the outside edge, moulding the compact sand into corrugations. Low, green stromatolite mounds made a marsh all along its inside. Behind us, on an expanse of featureless dunes, nothing grew at all. I looked down the spit, out to sea.

A splas.h.i.+ng started within its curve. The water began to froth as if it was boiling. Creatures like lobsters were jumping out and falling back, lobes along their sides flapping. They had huge black eyes like doork.n.o.bs. One flipped up, and in an instant I saw ranked gills and an iris-diaphragm mouth whisk open and gnash shut.

Hundreds of crab-things scuttled out of the waters' edge; their pointed feet stepping from under blue-grey sh.e.l.ls with arthropod finesse. There were long, spiny worms too, undulating on seven pairs of tentacle-legs.

'Something's chasing them,' said the Vermiform. 'Oh no. No! It's here already!'

The patch of frothing water surged closer. Cyan and I stared but the Vermiform started knitting itself around us frantically. Different parts of it were gabbling different things at once: 'Eat the d.a.m.n trilobiteshallucigeniaeat the anomalocarisbut LEAVE US ALONE!'

Straight out of the froth the Gabbleratchet rode, without disturbing the water's surface by so much as a ripple. Dry hooves flying, the stream of hunters arced up against the sun. Red eyes and empty sockets turned to us Endless salt flats. The vast ruins of a city stood on the horizon, its precarious tower blocks and sand-choked streets little more than rearing rock formations in the crusted desert that was once the ocean bed.

'I've been here before,' I said. 'It's Vista.'

'What's that in the distance?' Cyan said, pointing at a bright flash.

'Probably a Bacchante tribe.'

'They're coming closer.'
