The 7:15 train is the only constant in Evan Cole's carefully controlled life.

Same route. Same seat. Same reflection in the window-until the night it knocks back.

Not from outside the glass.
From inside.

When his reflection begins moving independently, Evan dismisses it as exhaustion. Stress. Tricks of light and motion. But the distortions accelerate: frozen train cars where time stutters, reflections that turn to watch him, and a presence that follows him home.

Then Amelia Reed appears on the platform with a warning: "You're running out of versions."

She knows because she's seen this before. Her partner Marcus started with small discrepancies-coffee cups on the wrong side of the sink, keys in unfamiliar pockets. Then he changed. Became something colder. More efficient. Wrong.

Six months later, most people don't remember Marcus existed at all.

Now Evan's therapist, Dr. Voss, admits she's been tracking him for months. Detective Harris has security footage proving Evan was in two places simultaneously. And the wooden box Voss gave him-the one that "helps you remember what's real"-might be the only thing anchoring him to a world that's already starting to forget he belongs.

On a bridge suspended between the city and the river below, Evan will discover the truth: there are multiple versions of him, branching from choices he never knew he made.

And only one can stay.

Some reflections don't fade when you look away. They get stronger.

A mind-bending psychological thriller exploring identity, choice, and the terrifying question: which version of you deserves to exist?

Perfect for fans of Dark Matter, The Echo Wife, and Bird Box.
