ACT I — THE PHONE CALL

The phone rang at four in the morning, which is to say it rang at the same time it always rang: four in the morning, when the city is neither asleep nor awake but somewhere in between, which is to say fully awake in a way that matters.

Jack Corwin answered on the third ring because he'd been waiting for it. He didn't know who would call at four in the morning unless it was someone who needed something that couldn't wait until dawn. And in New London—though nobody called it that anymore, back when it was a city and not a coordinate on a ruined map—there were very few things that couldn't wait.

"This is Corwin."

"Mr. Corwin? This is— I don't have a name. The person who sent me said to tell you that Last Hope Colony is gone."

Jack sat up in bed. The room was small and cold and smelled of old tobacco and older decisions. "Gone how?"

"Completely. No survivors. No distress signal. Just— empty."

He thought of the file he'd been keeping for eight months, thick with newspaper clippings and colonial office reports and a single handwritten note from a woman he'd never met: *The barrier is thinning. When it opens, do not be afraid.*

"How long has it been empty?"

"Since last Tuesday. Maybe Monday. The people who were supposed to check it didn't go because the transport budget was cut and the orbital path was blocked by debris and— "

"Who didn't go?"

"The colonial office. Or what's left of it."

Jack hung up and dressed in the dark. He didn't bother with lights; his apartment was small enough that he could navigate by memory, and memory was one of the few things the collapse of civilization hadn't touched. He pulled on his coat, his boots, his gun— not because he expected trouble but because trouble found him whether he carried or not.

ACT II — THE VESTIGE

Last Hope Colony was not a city. It was a research outpost, one of twelve that had been established along the orbital rim of the New London system, each one a small metal bubble parked at the edge of known space and staffed by people who had volunteered for isolation in exchange for the privilege of watching the stars through telescopes that cost more than most American houses.

When Jack arrived—on a transport that wasn't supposed to exist and a pilot who wouldn't meet his eyes—the outpost was exactly what he'd expected: empty. Not ransacked. Not destroyed. Just empty, as if the people who lived there had simply stood up and walked away and forgotten to close the door.

The mess hall had coffee pots full of dregs. The quarters had clothes in them, hung on hooks, as if their owners were just in the bathroom. The observation blister had a journal open on its desk, the pen resting on the last written page like a bird that had landed and forgot to fly away.

Jack read the journal.

*Day 1,047: The barrier is at sixty-eight percent. Julian says it will open in approximately eleven months. I don't know what "open" means. I don't think anyone does. But the Council is asking questions, and Marcus wants to scuttle the eastern array, and I keep thinking about the letter I received from the deep archive and whether it was sent by someone who knew this would happen or by someone who hoped it wouldn't.*

*If you are reading this, I am either gone or changed or both. The laboratory beneath the eastern wall is where Julian has been spending his time. I don't understand what he's doing. I don't think he understands it either. But he built something—a machine, a generator, a prayer—that is connected to the barrier, and when it activates, something will happen that neither of us can predict.*

*My name is Eleanor Ashworth. I am the administrator of Last Hope Colony. I have been a terrible administrator. I value life above efficiency, which in practice means I value the lives I can see above the lives I cannot. I hope someone smarter fixes what I have broken.*

Jack closed the journal and found Margaret "Maggie" Vance's file three hours later, buried in the administrative records: administrator, assigned eighteen months ago, background in colonial governance, education at New London Academy, no family, no dependents, reason for assignment: "volunteered under unusual circumstances."

"Unusual circumstances," Jack muttered. He found the circumstances two days later, in the laboratory beneath the eastern wall.

ACT III — THE MACHINE

It was a beautiful thing, in the way that only machines built by people who believe in something can be beautiful. Copper coils wound around crystalline matrices, arranged in patterns that weren't quite mathematical but were close enough that Jack's mind ached when he tried to follow them. The machine hummed with a soundless energy, the kind of energy that existed outside the range of human hearing but inside the range of human dread.

And on the far wall, scratched into the concrete: *Julian.*

Just the name. No title, no credential, no explanation. Just a man who had built a machine to thin a barrier between dimensions and then carved his name into the wall as if to say: I was here. I did this. I believed.

Jack sat in the laboratory for six hours, reading every document, every note, every fragment of a scientific paper that had been abandoned mid-sentence. He found the letter—three of them, stacked neatly in a drawer. One addressed to the Council, who would never read it. One addressed to himself, which had been lost. And one addressed to "the person who would still be here when Kepler-7 went dark."

He found Maggie's personnel file and read the part that explained everything: *Miss Vance assumed the role of administrator following the departure of Eleanor Ashworth under circumstances classified by the colonial office as "unusual." Miss Vance's tenure lasted fourteen months. Her final report was sealed.*

"Sealed by whom?" Jack asked the pilot when he returned to the transport.

The pilot, a young man with old eyes who had agreed to fly the trip for payment in something that wasn't money but was close enough, shrugged. "Colonial office. Or what's left of it."

"Which is to say?"

"Nobody knows. The office doesn't know. The people who pay me don't know. The government doesn't know." The pilot paused. "The people who built the machine don't know."

Jack looked out the window at the stars. They were the same stars Eleanor Ashworth had watched from her observation blister. The same stars Julian had measured with his telescopes. The same stars that had driven a woman to carve a name into a concrete wall and leave a letter for someone who might read it a thousand days later.

"What happened to the barrier?" he asked.

The pilot didn't answer immediately. When he did, his voice was quiet: "It opened. Or it thinned. Or it did whatever it does when it does it. And then—" He stopped. Started again. "And then Last Hope Colony became something that the colonial office can't classify. And that means it became something that the colonial office can't control."

ACT IV — THE SIGNAL

Jack Corwin sat in his apartment on the twenty-third floor of a building that had once housed a law firm and now housed a man who knew too much and not enough to do anything about it. He spread the documents across his desk: Eleanor's journal, Julian's scientific notes, the three letters, Maggie's sealed report (which he had not, he admitted to himself, actually read because some things are better left sealed).

The phone rang.

"Mr. Corwin?" It was the same voice from the first call. "The barrier signal has strengthened. We're seeing pulses from Last Hope. They're— they're different now. Not the old pattern. New pattern."

"What pattern?"

"One pulse. Then a pause. Then one pulse. Then a longer pause." The voice hesitated. "Like a heartbeat."

Jack hung up and walked to the window. The city below him was dark and broken and alive in the way that broken things are alive: not thriving, but refusing to stop. The stars above were the same stars Eleanor had watched, the same stars Julian had measured, the same stars that had connected them across twelve hundred thousand miles of dead space through the patient language of light.

He picked up a pen and began to write. Not a report. Not a classified document. A letter. Addressed to nobody in particular, which is to say addressed to everyone.

*My name is Jack Corwin. I am a private investigator, which means I am someone who knows more than I should and is paid to know less than I know. I have just returned from Last Hope Colony, which no longer exists as a colonial outpost but exists as something else— something that the colonial office cannot classify because it does not fit their categories.*

*What I found there was not destruction. It was transformation. The people who lived there—the administrator, the scientist, the security chief, the fourteen who waited in the mess hall for a woman who went to find an answer— they didn't die. They crossed something. A barrier. A membrane. A line that had been drawn by people who thought they were protecting the colony from the vacuum outside and were actually protecting the vacuum from the colony.*

*I don't know where they are now. I don't know if they are human anymore. But I know this: the barrier is thinning. The signal is strengthening. And whatever is on the other side has been waiting for us.*

*If you are reading this, you are either brave or curious or both. Neither will save you. But curiosity might.*

He folded the letter, addressed it to nobody, and placed it in a drawer beside the journal and the letters and the scientific notes. A pile of documents that told a story too large for any single person to hold. A story that was no longer Eleanor's or Julian's or Maggie's or even Jack's.

It was everyone's.

A single drop of rain fell from the window ledge, rotated in the neon light of the city below, and refracted a spectrum that contained colors no American eye had seen since the stars stopped talking and started singing.
