Chapter 1
The last train never appeared on any schedule.
People in the town of Larkspur spoke about it quietly, like it might hear them if they said too much. It only came at night, only when the fog rolled in thick enough to swallow the streetlights. No one knew where it came from. No one knew where it went.
But everyone agreed on one thing: if you boarded it, you didn’t come back the same.
Mara had spent her whole life in Larkspur, watching people leave in ordinary ways—cars packed with boxes, tearful goodbyes at the station, promises to visit that slowly dissolved into silence. She told herself she’d leave too, one day. Somewhere bigger. Somewhere brighter.
But “one day” had a way of staying far away.
Until the night the fog came.
It started as a thin veil, curling around her ankles as she walked home from work. By the time she reached the station, it had thickened into something alive, pressing close, muting the world. The platform was empty.
Except for the sound.
A low, distant rumble. Not quite thunder. Not quite machinery. Something in between.
Mara froze.
There were no trains scheduled. Not at this hour.
The sound grew louder. The fog trembled, as if something massive was pushing through it. Then, slowly, a shape emerged—dark metal, old-fashioned, its windows glowing faintly like watchful eyes.
The train.
Her first instinct was to run. Everyone knew the stories. People who boarded came back… different. If they came back at all.
But then she thought about her apartment. Her job. The same streets, the same faces, the same quiet ache of wanting something more.
The doors slid open with a soft hiss.
Inside, the train was warm. Not bright, not dark—just… dim. Comfortable. Like it was trying not to scare her. The seats were empty.
Waiting.
Mara stepped back.
“This is stupid,” she whispered to herself. “It’s just a train.”
But she knew it wasn’t.
A voice drifted from inside. Calm. Neither male nor female. “You don’t have to stay, you know.”
Mara swallowed. “Where does it go?”
A pause. Then: “Where you need to be.”
That wasn’t an answer. Or maybe it was the only answer.
She looked behind her. The station was gone—just fog, endless and thick. Forward, the train waited. Patient.
“You’ll come back?” she asked.
Another pause. “That depends on you.”
Mara let out a shaky breath.
“Yeah,” she said softly. “That figures.”
And before she could change her mind, she stepped inside.
The doors closed.
The train moved.
At first, nothing happened. Just the steady rhythm of wheels on tracks. Mara sat near a window, but the glass showed nothing but darkness. No town. No lights. No reflection.
Then, slowly, shapes began to form.
Not outside.
Inside the glass.
She saw herself—years younger, laughing with friends she hadn’t spoken to in ages. The image shifted—her standing at a crossroads, choosing the safe path. Another shift—an opportunity she’d turned down, a risk she hadn’t taken.
Mara leaned closer. “What is this?”
“Possibilities,” the voice said gently. “The ones you chose. The ones you didn’t.”
The images kept changing.
A version of her in a different city, tired but alive in a way she’d never felt. Another version, older, still in Larkspur, wondering what might have been.
Mara’s chest tightened. “So what—this is a regret tour?”
A soft, almost amused reply: “No. It’s a choice.”
The train began to slow.
Outside the window, the darkness peeled back to reveal a city—tall buildings, glowing windows, the hum of life. It felt unfamiliar. And yet…
Possible.
The doors opened.
Mara stood, her heart pounding. “If I get off…”
“You move forward,” the voice said.
“And if I don’t?”
The train gave a gentle shudder. “Then you return.”
Mara looked at the city. Then at the empty seat behind her.
For the first time in a long while, “one day” didn’t feel far away.
It felt like now.
She smiled—small, nervous, real.
“Okay,” she said.
And she stepped off the train.
