He said he loved her.
He said he’d never leave.
He lied.

When Olivia Reed comes home to find her boyfriend Callum gone — not just missing, but vanished without a trace — her life begins to unravel. His clothes, his photos, every sign he ever existed… wiped clean. It’s as if Callum was never real at all.

But Olivia remembers. She remembers his touch, his voice, the way he made her feel safe. So why can’t anyone else remember him the same way? And why do the fragments of his past seem to crumble under scrutiny?

As Olivia digs deeper, determined to uncover the truth, the lines between memory and her own past begin to blur. And what she finds isn’t just about Callum — it’s about her. About the secrets she’s buried. The things she’s tried to forget.

Because the most dangerous lies are the ones we tell ourselves.
And some love stories were never meant to have a happy ending...
