The space between walls was so tight it pinched her shoulders. She did not notice. Her head was full of fast black dragons. What had been invisible to her, because ubiquitous, now stood revealed. She heard them scream supersonic across the sky, fueled by wrath and gasoline. She felt the gravitational pull of them, the superheated backwash of their passing. And she saw herself riding one away, away, away.

First, though, she would have to master the grimoire. She would have to learn how the dragons were operated.

For hours Jane pored over the book, gently touching and internalizing the chapter sigil by sigil. She finished her first reading of it in time for breakfast. She crawled out of the wall just as the wake-up whistle blew, and was marched off to eat, yawning, bone weary and happy.

The next night, for the first time, she heard the dragon speak to her.

Three days later Jane, Dimity, and Thistle were taken to the machine shop. The regular work spaces were all claimed, and after some argument with the shop supervisor Blugg took a box of machine wheels under his arm and led them upstairs. A balcony-level string of rooms ran completely around the building there. It was junk space, but Blugg found a place for them between a wooden stairway and the brick chimney-top of an industrial alembic. They were given a rickety wood bench at a window ledge, and told to wipe the wheels clean of grease.

Then Blugg left.

The window had long ago been painted over, glass and all, with white or green or gray paint—it was hard to guess which now—and there was a gap of at least a foot between the upper sash and the top of the frame, glued permanently open. Chill air poured down on them. A brown enameled kerosene heater wedged under the stairway strained to offset the cold.

"Trade places with me," Dimity said, as soon as Blugg was gone. "Thistle and I want to be closer to the heater."

Jane almost refused. But Dimity was always complaining about the cold; it was possible she felt it more. And Thistle was smiling in rather a mean way. It was probably best to give in to them on this one.

She stood, walked to the far side of the bench, and sat down again without saying a word.

The cogwheels were the size of silver pennies but much thinner, with fine teeth that prickled when touched edge-on. The grease on them was an almost translucent brown, and had hardened so that it did not come off easily. They worked industriously, knowing that Blugg would pop up to look in on them regularly.

But the inspections never came. Hours passed. Blugg seemed to have forgotten them completely.

Jane stared sightlessly ahead as she worked, her thoughts on the grimoire and on the dragon's voice she was still not entirely sure that she heard speaking to her at night. She dreamed of gleaming ebon flanks and smooth, streamlined surfaces, of strength and endurance wedded to ruthless speed. She imagined her hand on the throttle, with all that fearsome power under her control.

Beside her, Dimity sighed.

The silvery-dull sunlight streaming in over the top of the window was suddenly divided by the fluttering shadow of wings. Dimity looked up and eagerly cried, "Toad eggs!"

"Toad eggs?" Thistle said dimly. "Eww. Whatever are you talking about?"

"Up there, under the roof. That's where they've built their nests." Dimity climbed up on the ledge and stood on tiptoe. She stretched an arm out the window as far as it would go, her tail twitching impatiently. There were several muddy blobs on the undersides of the eaves. "Damn! I can't quite…"

"There won't be any eggs," Jane pointed out. "Nothing lays eggs in the autumn."

"Toads do. It's not like the spring clutch; it doesn't hatch. They store them away for the winter, so they'll have something to eat during the Axe Moon." She looked down, a strange smile twisting her wide mouth. "Jaaane! Climb out there, and fetch me in some eggs."

"I'm no climber! Why don't you get Smidgeon or Little Dick or…"

"They're not here." She exchanged glances with Thistle, and before Jane could react, the shifter had seized her and thrust her up alongside Dimity. The young feys were both preternaturally strong. Laughing, they stuck her out the window and shoved. The box of cogwheels was kicked over, and little metal wheels went spinning and rolling away. "Out you go, my lovely!" Dimity sang.

Jane clutched wildly at the frame. Cold wind blew in her face, forcing tears to her eyes. Across a cinder-paved courtyard, Building 6 reeled up at her, dark clouds scudding above. Below and to one side, she saw the tar paper roof of a utility shack, dotted with bits of brick and old soda bottles. It was at least a thirty-foot drop.

"Oh, holy Mother!" Jane gasped. Desperately, she struggled to pull herself back in.

But tough, merciless hands pried her fingers free. With a jar, she was pushed out into the void. Flailing, afraid she would throw up, she squeezed her eyes shut tight and grabbed for the window frame. Her weight rested atop the upper sash now. Only her legs were inside.

"Don't wriggle, you'll make us drop you."

She had hold of the frame again. Brittle flakes of paint crunched under her fingertips. She pulled herself flat against the building, brick scratching her cheek. The sweet, pungent smell of toad droppings filled her nostrils. The outside top of the frame was white with them. It was cold out here, too. She shivered convulsively. "Oh, please let me in," she babbled, "sweet Dimity, I'll do anything you ask me, I'll be your best friend, only—"

"Here." A hand shot out with a plastic bag in it. "Fill this up, and you can come back in again." One of Jane's shoes had fallen off and now she felt Thistle peel her sock back. A sharp fingertip drew itself up the center of her foot, paused, then waggled at the softest part of her flesh. "Stop that tickling! If she falls, I won't get any eggs." The hand moved impatiently up and down. "Take the bag."

Jane obeyed. She took a long, deep breath, and opened her eyes. Her head and stomach were so dizzy-sick that it took her a moment to realize that she was staring up at the underside of the eaves. There must be twenty nests up there, warty and bulging things with a hole to one side, like ill-made jars.

The toads had scattered when she first emerged from the window. They fluttered in agitation not far off, their black-feathered wings beating hysterically. They were loathsome things, the miscegenated get of jackdaws upon their lustful batrachian dams, and like their sires they were notorious thieves. Their nests were ordinarily kept cleared away from the roofs because they had a fondness for shiny objects and, unlike most wild things, had little or no fear of fire. They had been known to torch buildings by filching lit cigarettes and carrying them back to their nests. They were a terrible hazard.

Trembling, she stretched out a hand. The nest was just out of reach. Unhappily, she knew that Dimity would never accept that as an excuse. Taking a long, steadying breath, she forced herself to lean back over empty air. With the arm clutching the window fully extended she could easily reach the nearest nest. She squeezed her hand into the opening.

The inside of the nest was lined with fine black down, silkily soft to her touch. She probed to the back of the nest, and found a clutch of sticky warm eggs. She scooped them out and straightened at the waist, returning to the window. Awkwardly she opened the bag and dropped the eggs within. They slid to the bottom in a mass.

She hadn't gotten all the eggs. She leaned back again to scoop up those she had missed. This time, she only got a half-handful, along with two bits of aluminum foil, a shard of broken glass, and a chromed hex nut. These last she let drop to the distant ground.

Second nest. She dredged out the eggs quickly. Just as she was withdrawing her hand, the wind whipped up, sending a blast of icy air right through her clothing. She knew better than to look down, but the sudden swirl of air made her feel especially vertiginous. She wanted to cry, from fear and frustration, but dared not.
