## I. Evelyn (2064)

The signal came from a patch of sky near the star Vega, and it was not mathematical. It was musical.

Dr. Evelyn Shaw was thirty-four years old, a radio astronomer at the Very Large Array in New Mexico, and she was the first human being to hear the song of another civilization. She sat in the control room alone at 3:17 AM on a Tuesday in March, headphones on, listening to a signal that was not noise. It had structure. It had melody. It had something that, impossibly, sounded like longing.

She recorded it. She played it back. She played it again.

On the third playback, she understood that the song was not art. It was data. Encoded in the melody were coordinates, and a warning, and something else that she could not name but felt in her chest like the memory of a place she had never been.

She called it the Siren signal. The name came to her without thinking, as though the civilization that sent it had chosen it themselves.

Two years later, she published her findings. The scientific community responded with cautious excitement. The signal was real. It was not natural. It was not a pulsar or a quasar or any known phenomenon. It was a song, sent from four point two light-years away, and it was the most important discovery in human history.

Her son Thomas was twelve. He sat on the kitchen floor while Evelyn worked at the dining table, surrounded by papers and recordings and equations. He listened to the Siren song sometimes, when she thought he wasn't paying attention. He said it sounded like a woman crying. Evelyn didn't correct him.

## II. Thomas (2098)

I left Earth because I couldn't stay.

Not that day, not right after the signal was published. But over the years, as the signal got stronger and the scientists got more excited and the governments got more nervous, I felt the world tightening around me like a fist. Everyone wanted to know what the Sirens meant. Everyone wanted to decode the song. Nobody asked whether we should.

I volunteered for the Mars colony program in 2089. Not because I was brave. Because Mars was far enough away that I could think.

The trip took eight months. I was one of three hundred people on the ship, packed into modules that smelled like recycled air and sweat and fear. Nobody spoke much. We looked out the windows at the stars going by and tried not to think about what was singing in the space between them.

On Mars, I built a house. Not much of a house—modular polymer panels bolted together in a pressurized dome, with a view of a red desert that stretched to a horizon that looked too close, as though the planet was smaller than it should be. I worked as a geologist, which was my profession, and I listened to the Siren signal when it grew strong enough to reach Mars, which was not often. It reached us fainter than it reached Earth, as though distance was already muting the song.

In 2095, my daughter Clara was born. She was my second child—our first had not survived the trip, something I have never spoken about. Clara was born on Mars, the first Shaw to be born on another world. She has her mother's eyes and my stubbornness and, I suspect, something else. Something I can't name.

When she was ten, I told her about the Sirens. I sat her on my lap in the dome, with the red dust pressing against the glass, and I played her the song.

She listened for a long time. Then she said: "They're sad, Daddy."

"Yes," I said. "They are."

"Are we going to answer them?"

"Not yet."

"Why not?"

"Because the universe is full of people who don't want to be heard, Clara. And the people who want to hear us might not be friendly."

She thought about this. "That's stupid," she said. "If you sing, someone should sing back."

She was ten. She didn't understand yet that not everyone wants to be found.

## III. Clara (2264)

I am seventy years old. My father is dead. My mother is dead. The Mars colony is a city now—three hundred thousand people living in domes and lava tubes, breathing recycled air and forgetting that the sky outside is mostly empty.

I stayed on Earth.

Not out of courage. Out of responsibility. The Seed Vault is here—deep beneath the permafrost of Svalbard, a facility built to preserve the genetic and cultural record of human civilization in the event of a global catastrophe. I am its guardian. Not officially. There is no official position for what I do. But someone has to be here.

The Siren signal is stronger now. It reaches every corner of the solar system. The colonies on Mars hear it. The stations on Jupiter hear it. Even the deep-space probes, voyaging through the outer dark, pick up fragments of the song as it passes.

And between the Sirens' song and the silence that follows it, I hear something else. Something fainter. Something that sounds like—

No. I will not name it. Naming gives it power.

I sit in the Vault every night, listening to the Siren song on a recording my father made, playing it through speakers that have grown old along with me. The song is beautiful. It is the most beautiful thing I have ever heard. And it is a warning. It is a prayer. It is a song for a civilization that knows it is not alone and is singing anyway, into the dark, hoping someone will hear.

I will not sing back. I will guard the seeds. I will keep the record. And when the end comes—and it will come, I know it will, the silence between the Siren's notes tells me everything I need to know—I will be here.

I will be here, in the cold and the dark, listening to a song from four point two light-years away, keeping the seeds safe, waiting for a dawn that may never come.

Let the sun shine on this world one more time. Let it shine while it can.
