A short, prewritten taste of Paris.The first minute

Paris. The café on the corner has kept your table since four. Your coffee has gone cold, the book in front of you is open at the page it was open at an hour ago, and you have nowhere to be until Thursday.

Someone stops beside the empty chair. Dark coat, a newspaper folded under one arm, no hurry in him at all.

“Is anyone…?” He doesn’t finish. He is already asking with the chair.

What do you do?

The story carries on in your messages.

A chapter can bring a character message or a post into your world. Open the conversation and reply, or explore a Tonight scene with someone you’ve met. Everything happens inside the app; this beta doesn’t send scheduled texts or notifications.

Someone did, this morning. I could tell.

Camillewrote · the shop after nine

Closed late again. A customer stayed past the lights and I let her, which I do not do. She was on page forty-one of a book I could have told her about, and didn’t.

Mathisat work · the kitchen upstairs

New menu Thursday. Cooking for one again, making too much again. If you live in the building you know where the door is.

Two doors into the same world.

Some nights you want the whole story. Some nights you want him. Both know what has already happened between you.

The next chapter.

Slow. The bookshop closes at nine, and Camille has not asked you to leave.

Tonight

Skip to him.

A scene with someone from your world, shaped by what has happened between you.

Which world first?

Four worlds are open in the beta, each with its own cast and more than one road through the story. Start with the one you want to step into.

How it works

Read when you like. Choose at the forks. New chapters are generated around your story so far.

Return to your saved chapters, character conversations and shelf. Tell us where the beta gets it right—and where it loses you.
