The stars over Long Island in 1926 were the same stars that had been over Long Island in 1826 and would be over Long Island in 2026, except for one thing: they were going out.

Not all at once. Not dramatically. One by one, the way a city turns off its lights at dawn—slowly, methodically, room by room, until the darkness is complete and nobody notices until it's too late.

Julian Cross sat at the piano in Whitmore's ballroom and played for people who weren't listening. They were dancing, drinking, laughing, throwing themselves into the kind of joy that only people who have survived a war and immediately forgotten why they survived are capable of. The band was loud. The champagne was cold. The chandeliers threw light onto a thousand faces that were all the same face—beautiful, empty, and running as fast as they could from whatever was coming.

Julian wasn't running. He was watching the sky.

Whitmore stood on the balcony above the ballroom, just as he did every night, every party, every week for the past three years. He held a brass telescope to his eye and looked at the stars. His expression was not one of wonder. It was the expression of a man watching a countdown he couldn't stop.

Julian had been watching Whitmore for two months. He'd seen the way the millionaire's hand trembled when he thought nobody was looking. He'd seen the way he never spoke at his own parties, standing on that balcony like a king who had inherited a kingdom he didn't want and couldn't give away.

And he'd seen the way Daisy Van Alen looked at him when she thought nobody was looking—which was often, because Daisy looked at everything often, as though the world were something that might disappear if she blinked.

The song ended. The dancers applauded with the mechanical enthusiasm of people who clap because clapping is what you do when the music stops and you haven't decided what to do next. Julian stood, bowed to nobody in particular, and stepped off the stage.

Daisy was waiting for him by the door. She was wearing a dress the color of champagne and a smile the color of something painted over damage.

"Play something sad next time," she said. "Something that sounds like the truth."

"I play what they ask for," Julian said.

"They don't know what to ask for," Daisy said. "That's the whole problem."

She took his hand and led him through the crowd, out the double doors, across the terrace, to the garden. The garden was full of people, but the edge of the garden was empty, and the edge of the garden was where Julian wanted to be. It looked out over the Sound, over the dark water, over the sky beyond the water where the stars were going out one by one.

"My father used to say," Daisy said, leaning against the stone railing, "that the universe is not friendly. Not evil. Just not friendly. Like a house full of rooms and most of them are locked and you don't know what's behind the doors."

"Your father was a philosopher."

"My father was an astronomer. There's a difference." Daisy turned to look at him, and for a moment the smile dropped and what was underneath was raw and young and terrified. "He died three years ago. Officially, heart failure. Unofficially, he stood on our roof with his telescope and watched the sky for six hours straight and then he walked into the ocean and didn't come back. They found his telescope the next morning. It was pointed at Centaurus."

Julian felt something move through him, slow as mercury. "Centaurus."

"Don't pretend you don't know about it." Daisy's voice was sharp, desperate. "Don't pretend you don't know why you're here. You're not here because you need a job playing piano in a man's backyard. You're here because your father told you to come here."

Julian looked at her. Really looked at her. She was twenty-four years old and she carried herself like someone who had learned very young that the world was not a safe place and never would be.

"My father is in a asylum," Julian said.

"I know."

"He thinks the stars are moving."

"They are," Daisy said. "Or something is moving in front of them. Or behind them. Or between them. I don't know the difference anymore."

She reached into her purse and pulled out a folded piece of paper. She pressed it into Julian's hand. It was an address. Boston. Mass general. And beneath it, written in a hand that shook: "Go to your father. He knows more than he knows he knows."

Then she was gone, swept back into the ballroom by the current of people who needed to be where other people were, because being alone with your thoughts was a luxury that the jazz age could not afford.

Julian went to Boston.

The asylum was white and clean and quiet in the way that institutions are quiet—not the quiet of peace, but the quiet of suppression. Every sound was managed, every movement regulated, every human impulse channeled into approved paths. Professor Alden Cross sat by his window and watched the sky through a crack in the curtains, as though the sky were a television he couldn't turn off.

"Dad."

Professor Cross didn't turn. "They're running, Julian. Can you see them? They're running from something."

"From what?"

His father turned. He was sixty-five years old and looked ninety. His eyes were wide and bright and completely sane in a way that was more terrifying than madness. "Do you know what happens when you light a fire in a dark forest?"

"Animals come to see what it is."

"No. Hunters come. And hunters don't bring food. They bring guns." He laughed, and it was the saddest sound Julian had ever heard. "I spent thirty years studying the stars, Julian. Thirty years. And I learned one thing: the universe is not empty. It's full. Full of things that learned, very early, very quickly, that the only safe thing to do is nothing. No signals. No lights. No civilization that makes noise. Because the first civilization that made noise in the dark forest was eaten."

Julian sat down in the chair across from his father's bed. The institutional mattress squeaked. Somewhere down the hall, a door closed. The silence returned.

"What are you saying?"

"I'm saying that every night for the past ten years, I've been watching certain stars get dimmer. Not fade. Dim. Like someone is putting a blanket over them. And the blanket is moving. It's moving from the center of the galaxy outward, and it's moving at nearly the speed of light, and when it passes a star, that star goes dark and it stays dark. Permanently. No supernova. No explosion. Just... dark. Like it was never there."

"How many stars?"

"Enough to fill a sky you've never seen." His father's voice dropped to a whisper. "Julian, I calculated the rate. At the current rate, it will reach our solar system in approximately forty years. Maybe fifty. Maybe less."

"Forty years." Julian repeated the number like a man testing a stone in his mouth to see if it's real. "Forty years. And what do we do?"

His father looked at him with eyes that were ancient and young at the same time. "That's the question, isn't it? What do we do? Do we tell the world and watch them spend their last forty years screaming? Or do we keep our mouths shut and let them spend their last forty years dancing?"

Julian left Boston three days later. He didn't say goodbye to his father. Some goodbyes are just another word for surrender.

He returned to Long Island and played piano at Whitmore's parties. He played upbeat numbers. He played ragtime and blues and songs with words about love and girls and champagne. He played until his fingers bled and his hands shook and the music sounded like laughter coming from the bottom of a well.

And he watched the stars.

One by one, they went out.

Not dramatically. Not all at once. Just one, then another, then another, in the constellation of Centaurus, in the direction of the blanket that was moving toward them at nearly the speed of light.

He told nobody. Daisy knew. Whitmore knew. A few others knew—men and women who had found each other through Julian's father's notes, a secret society of people who had looked at the sky and seen what was coming and decided, collectively, to say nothing.

They called it "The Great Silence." Not because the sky was silent. Because the thing moving through the sky was silence itself. A silence so complete, so absolute, that when it passed, the stars didn't just go dark—they were forgotten. As though they had never existed.

Julian played piano every night. The jazz got louder. The parties got wilder. The champagne flowed like water. People danced until they collapsed. People loved until they broke. People lived with the kind of reckless abandon that only comes from knowing, deep in your bones, that there is no tomorrow.

And Julian played.

He wrote a song called "The Last Waltz." It was the saddest song he had ever written and the most beautiful. It sounded like a funeral and a wedding at the same time. It sounded like a mother singing to a child she knew she would outlive. It sounded like the last person standing in an empty ballroom, playing for ghosts who hadn't died yet.

He played it one night. The dancers stopped. The musicians stopped. Even Whitmore stopped looking through his telescope. For three minutes and forty-seven seconds, nobody moved. Nobody spoke. The music filled the room like water fills a room when the walls are already gone.

And then the music stopped. And the dancing started again. And the champagne flowed again. And the stars went out.

But for three minutes and forty-seven seconds, everybody had listened. And that was enough.

That had to be enough.
