The terminal blinked at him like a single unblinking eye.

Jack Callahan had found it on a Tuesday, which was unremarkable because Tuesdays in LA were the same as every other day—just slightly less busy, slightly less desperate. The basement of the old Mayflower Studios had been condemned for three years. The walls were covered in peeling murals from the studio's glory days: actresses with perfect teeth smiling at nothing, landscapes painted to look like the places they'd never actually been. Jack was there because a guy he knew owed him fifty bucks and had said, "Meet me in the Mayflower basement. I'll show you something that'll make you rich."

The guy never showed. But Jack found the terminal.

It was an ancient thing, all wooden casing and green CRT screen and a keyboard with keys worn smooth by someone else's fingers. The screen displayed a single line of text:

> COORDINATE INPUT: PAGE / LINE / WORD

Jack typed "1 / 1 / 1" because he was bored and the screen made him feel things he couldn't name.

The screen flickered. The text changed. And then Jack was looking through a window into a library.

Not a screen. A window. He could see the dust motes in the library's air, the way the afternoon light fell through high windows onto shelves of leather-bound books, the smell of old paper and floor wax that reached him even though his fingers were touching glass. He pressed his face closer. The library stretched for what seemed like miles, shelf upon shelf upon shelf, and on the nearest shelf he saw a book with a title he recognized: a novel he had read as a boy, the one about the engineer who built a machine that could predict the weather.

He reached through.

His hand passed through the glass like it was water. His fingers closed around the book. He pulled it back and held it in his hands. It was real. It smelled like the library. It was warm, as if the sun that had shone on it in that other world was still on its covers.

When he set it down on the terminal's wooden casing, a patch of the wall behind it went blank. Not painted over—blank. The plaster was smooth and featureless, as if that section of wall had never existed.

Jack didn't notice. He was too busy opening the book and reading the first page, and as he read, he understood the engineer's mathematics, and the understanding settled into his brain like a key sliding into a lock.

He went home to his apartment that night knowing meteorology and forgetting his high school chemistry teacher's name. He thought nothing of it. Teachers' names didn't matter. Weather prediction did.

The second crossing was worse.

He input "42 / 7 / 3"—page 42, line 7, word 3 of a detective novel he'd found in the terminal's bookshelf—and the screen showed him a hospital room. A woman lay in a hospital bed, unconscious, and beside her a doctor was explaining a treatment that could save her. Jack reached through, took the medical knowledge from the doctor's mouth, and brought it back. In his apartment, he called a number from memory and spoke to a doctor friend about a rare condition he'd never studied. His friend was impressed. "Where did you learn about that?" Jack didn't answer because he couldn't remember what he'd learned before he learned it.

He lost his ex-wife's name that day. Sandra. He knew it was her name—he'd signed the divorce papers with it—but the sound of it, the way she'd said it when she was angry, when she was laughing, when she was saying goodbye: gone.

By crossing 15, Jack had built a pattern. He knew the rules: input coordinates from any book, access that world, take back something useful, lose something from his own life. The terminal was a trading post. It didn't care what it was trading.

He used it to survive. Medical knowledge to help Mrs. Chen in 4B with her diabetes. Engineering schematics to fix the radiator in his building so the superintendent stopped yelling at him. Combat techniques from a war novel that kept three punks from breaking his fingers in an alley behind a bar on Sunset.

Each crossing was a negotiation. Each crossing was fair.

He met "The Ghost" on crossing 23.

The Ghost was in a world that looked like a prison—but it wasn't a prison. It was a world the terminal had shown Jack before, a novel about political prisoners, and there in the corner sat a man who looked like he'd been there for decades. His hair was white. His clothes were rags. His eyes were the eyes of someone who had forgotten his own name and was no longer interested in finding it.

"You're using the terminal," The Ghost said. It wasn't a question.

"Yeah," Jack said. "You too?"

"I used it 41 times."

Jack sat down. The prison floor was cold. "What did you get?"

"Everything," The Ghost said. "And nothing. I know every language that's ever been spoken. I can build anything from scrap. I can recite every book I ever read word for word. And I can't remember my daughter's face."

Jack felt the cold spread through him. "What happened?"

"I gave it everything," The Ghost said. "My memories. My name. My life. And what did I get in return? Knowledge. Useless, beautiful, devastating knowledge. The terminal doesn't give you anything, man. It trades you. You think you're pulling knowledge out of those books? You're feeding it your memories. It eats them. That's all it does. It eats."

Jack left the prison world without another word. He went home to his apartment and sat in front of the terminal for three hours, staring at the green text.

> COORDINATE INPUT: PAGE / LINE / WORD

He input "1 / 1 / 1" again. He needed to know if the library was still there.

It was. The dust motes. The afternoon light. The smell of old paper.

He reached through. This time, he didn't take a book. He took a memory.

He took his own memory—the memory of crossing 1, of reaching into the library and pulling out a book and understanding weather prediction for the first time. He pulled the memory out of his own mind, felt it unravel like thread from a spool, and fed it into the terminal through the glass.

The screen displayed: TRANSACTION COMPLETE. COST: ONE MEMORY. GAIN: ONE MEMORY.

He was being fed back his own memory. The terminal was recycling him.

He made 24 more crossings. Each one took more of him. By crossing 40, he couldn't remember why he was doing this. He knew he needed something—something important—but he didn't know what. By crossing 45, he couldn't remember his own name. He looked at the driver's license on the terminal's casing and read "JACK CALLAHAN" the way you read a name on a stranger's wallet.

Crossing 46 was the last one he chose.

He didn't input coordinates. He just typed random numbers, and the screen showed him a world he recognized: his own apartment, his own body, himself sitting at the terminal, typing numbers. The loop was visible now, like a snake eating its own tail. He was feeding himself. The terminal was using his own memories to power his own crossings, creating a closed circuit where the only thing being consumed was the space between who he had been and who he was becoming.

Crossing 47: he typed numbers blindly. The screen showed him a man sitting at a desk in a city he didn't recognize, in a life that was never his. The man was Jack Callahan. Jack was the man. The terminal displayed:

> FINAL TRANSACTION COMPLETE.

The screen went black.

In an apartment on the west side of Los Angeles, a man sat at a desk he didn't recognize, in a city he didn't remember, looking at a terminal that had gone dark. He had been sitting there for hours. He had been sitting there for days. He didn't know which.

He stood up. He walked to the window. He looked out at a skyline he couldn't place and felt nothing. Not sadness. Not fear. Not even emptiness. Those were emotions, and he had given them away, crossing by crossing, memory by memory, until there was nothing left that could feel anything at all.

He sat down. He opened a book. He began to read. He didn't know what he was reading. He didn't know that he had once known what reading was.

The terminal sat behind him, dark and quiet, waiting for the next human being to find the basement of a condemned studio and type a single coordinate into a screen that was not a screen but a mouth.
