ONE CAME BACK is a beautifully written and gorgeously tense debut novel that unites the chill of the modern gothic with the hook of a thriller to explore the depths of loss, memory, mental health, grief and obsession.

It's New Year's Eve in Edinburgh when Emily sees Nicky. Well, she thinks she sees Nicky. He looks like Nicky, he laughs like Nicky, he moves just like Nicky. But Nicky died when they were teenagers in the highlands.

It's a week later when Emily meets Nicholas and he not only looks like Nicky grown up . . . he also knows some things that only Nicky should know.

As Emily's encounters with Nicholas become more frequent, and her fixation intensifies, we are left to ask what's really going on. Is this a ghost story? Is it something darker? Is Emily simply going mad?
