The line between fear and obsession isn't blurred - it's tightening.
The first time Sean saw the man outside his window, he was sixteen - skinny, terrified, and convinced no one would believe him.
The sightings didn't stop. They evolved.
A shadow at the end of the hall. A shape in the trees.
A presence that never left a trace - except in Sean's life.
Nearly twenty years later, Sean lives alone, off-grid and off the radar, certain that whatever started that night is still watching.
Grace has handled paranoid clients before. People who swear someone is chasing them.
Sean is different.
Because this time, there's proof.
And if someone has followed him for two decades without being caught, they're not playing games.
They're preparing.
Now Grace has one job: uncover the truth before the man outside the window stops watching - and finally makes himself known.
