Chapter I

She danced because the silence was louder than the music.

Catherine Valentine moved across the floor of the Gilded Nebula nightclub in New York's Lower East Side, her fringed dress catching the neon light like scattered confetti. She was twenty-two, born in some drab Ohio town where the biggest event was the arrival of the mail train, and now she was the talk of the speakeasy circuit—dancing to the jazz, drinking forbidden gin, smiling with eyes that looked past the crowd to something just out of reach.

"Cat, darlin', you're doing it again," said Tom Clare, hunched over the piano keys, his fingers finding chords that made the room seem to hold its breath.

"Doing what?" she asked, though she knew.

"Looking like you're waiting for a train that's already left the station."

Tom was a jazz pianist—a good one, though he played with one finger most of the time, thanks to an injury in a mining accident back in '19. He was gaunt, with dark circles under his eyes and a cough that rattled in his chest between sets. Nobody knew where he came from or where he was going. He played three nights a week at the Nebula, drank whiskey at home, and wrote things in a leather notebook he kept locked in a drawer.

The year was 1927. The stars had been colonized—Mars had its cities, Venus had its mining outposts, and the outer planets were dotted with research stations and corporate settlements. Humanity had reached out and touched the cosmos, and the cosmos had not reached back. The universe was a vast, empty room, and humanity was the only party in it.

That was what Cat danced about, though she never put it into words. The emptiness that made the jazz sound sweeter and the gin burn sharper and every hand she touched feel like it might dissolve into starlight.

Chapter II

The invitation arrived on a morning in April, delivered by a Star League courier in a uniform that shimmered like oil on water.

Cat was still in bed when she read it. The Star League had selected her as the Guardian Angel—the cosmic equivalent of being chosen to hold the match that would light or burn the world. The position had no salary, no title, no duties listed on paper. But everyone who knew anything about it understood: the Guardian Angel was the heart of the deterrent, the great system Commodore Roger Black had built over twenty years of service.

"Commodore Black is expecting you," said the courier, who did not blink.

She went. Of course she went. Cat always went—straight toward the thing she was afraid of, straight toward the thing that would change her.

Commodore Black was in his study on the thirtieth floor of the Star League headquarters, overlooking the East River. He was a tall, thin man with a face like a blade and eyes that had seen things that made him flinch at night. He did not hug her or shake her hand. He simply poured two glasses of bourbon and sat down.

"Do you know what they want you to do?" he asked.

"No," she said.

"It is what they think you can do. Feel everything too much. That is what you are, isn't it? You feel everything."

She thought of the nightclub, the music, the crowds of people dancing to drown out the silence. She thought of Tom, hunched over those keys, writing things in his notebook that she hoped he would never let her read.

"I suppose I do," she said.

Black nodded, almost sadly. "Then you will break us, Cat. But you will break us beautifully."

Chapter III

The dimensions began to collapse on a Tuesday.

Dr. Francis Shaw found her on the observation deck of the Star League building, watching the city lights blur through rain on the windows. Shaw was the League's chief astrophysicist—a quiet man in his thirties with Parisian manners and a mind that could hold entire galaxies in his head. He had come to the League from the Sorbonne, where he had studied under the great minds of interstellar cosmology, and he carried with him a love of poetry that he never quite hid.

"Cat," he said. "We need to talk."

She turned, and saw that his face had gone pale. "What is it?"

"Tom Clare's five fairy tales. We decoded them last week. They described what's happening—exactly what's happening."

She knew Tom's tales. Everyone dismissed them as the work of a mining casualty who had lost his mind to coal dust and whiskey. But the mathematics inside the verses—the curvature drives that could bend space into shortcuts, the dark domains that could hide civilizations from the universe's predators, the sealed worlds that fit inside rooms.

"The five tales—" she began.

"—contain the keys to survival," Shaw finished. "But we waited too long. The Star League abandoned the warp program the moment the deterrent held. Now we are naked. And the thing that is coming—it does not care about our weapons."

"Can we run?" she asked quietly.

"We can. But not everyone can. The evacuation fleet—the ships with warp capability—they leave in days."

She thought of Tom, with his single finger on the keys, and the locked notebook, and the way he looked at her when she danced, as if she were something precious he could not bear to touch.

"I need to see Tom," she said.

Chapter IV

He lived in a tenement on the Lower East Side, above a laundromat that smelled of lavender and steam. When she knocked, he opened the door with his bad hand and stood there, blinking, as if she were a ghost or a miracle—perhaps both.

"Cat," he said. "You shouldn't be here."

"I need to give you something."

She handed him a small envelope containing the last of her money—everything she had earned from the clubs, everything she would never need again. He took it with his good hand, and for a moment their eyes met, and she saw in his face a universe of things he could not say.

"Tom," she said. "The tales. The warp drives. The sealed worlds. I want one. I want the best one you have."

He looked at her for a long time. Then he went to his desk, unlocked the drawer, and took out a single sheet of paper—a contract for a sealed micro-universe. It was forty cubic metres, numbered 647, containing a small estate with a garden and a greenhouse. He had been saving it for years, waiting for the right moment, the right person.

"I bought this one once," he said. "I always had it ready for you."

She took the paper, and her hand touched his, and the single point of contact was enough.

Chapter V

The dimension collapse was like origami performed by a god.

Shaw had explained it to her in the observatory, showing her holographic projections of the process. Space was folding inward, losing a dimension, and everything—every building, every ship, every person—was being flattened onto a surface that had no depth. Mars went first. Then Venus. The mining colonies on the asteroids were the last to vanish, their final moments captured in telescopic images that showed them stretching thin, like watercolour paint spread across paper.

Cat stood on the deck of the evacuation ship with Shaw beside her and Tom behind her, watching the city of New York disappear into the two-dimensional plane. The lights went out one by one, like stars being extinguished. The buildings stretched into vast, flat paintings of themselves, and then even those paintings faded.

"Come," Shaw said, taking her hand. "We must go through the Void Shortcut."

The Void Shortcut was a tunnel in the fabric of spacetime—Tom's final tale, the one he had never written down but had hummed while she danced, a melody she now understood was a set of coordinates. They stepped through a door in the ship's hull and found themselves in a place that was not a place, a passage between universes that was neither dark nor light.

On the other side was a new world. Mars, but not Mars—the same coordinates, rebuilt by forces she did not understand, a second chance for everything that had been lost.

Cat walked across the red soil of the new Mars with Shaw's hand in hers and Tom's footsteps behind her, and she felt, for the first time in her life, the silence inside her was filled.

In the greenhouse of the sealed universe 647, left behind in the dying old cosmos, a blade of grass held a drop of dew. The dew rotated upward, caught the light, and became a tiny sun—a crystal star in the endless dark, singing a song too quiet for any ears but eternity's.
