Some friendships never die.

Emma has spent her whole life talking to Hannah — the best friend no one else can see. Everyone thinks she’s losing her mind… until her mother reveals a horrifying truth: Hannah drowned when they were seven years old.

As buried memories claw their way back to the surface, Emma realizes the girl who has followed her for years isn’t imaginary.

She’s waiting.

And every night at 3:34 AM, Hannah comes a little closer, whispering the same terrifying words:

“You should’ve died with me.”
