When the Sky Fell Twice (en Inglés) - Haley Nicole Burke

Nova knows something is wrong with the world.

It started the day the sky fell once before twice

Now people around her aren't just changing.
They're appearing.

Copies.
Versions.
Reflections of lives that shouldn't exist.

And one of them looks exactly like her, but only to people close in her life.

As reality begins to fracture, Nova is pulled deeper into a truth no one fully understands, one where identity isn't fixed, memory can't be trusted, and every version comes with a choice.

Some choose to stay.
Some choose to disappear.
And some never get the chance.

But the closer Nova gets to the truth, the more she realizes:

This isn't happening to the world.

It's happening to her.

And by the time it ends,

Only one version of each life may remain.
