On impact, the boy seemed to fold down and disappear, as if maybe he hadn't been there in the first place...

It's New Year's Eve in Edinburgh when Emily sees Nicky. Or at least she thinks she does. He looks, laughs, and moves just like Nicky. But how can that be? Nicky died when they were teenagers, in an accident on a remote road up in the Highlands... didn't he?

A week later, Emily sees the man again. He says his name Nicholas. This man not only looks like an adult version of her friend, but he also knows things that only Nicky should know.

As her encounters with Nicholas become more frequent and her fixation intensifies, the truth becomes murkier, and more unsettling.

Is Emily being haunted, is she going mad - or is something altogether darker going on . . .

One Came Back is a powerfully tense debut novel combining the chill of the modern gothic with the hook of a thriller, exploring the depths of grief, memory, and obsession.
