Winner of Audible 2017 Narrator of the Year Award.

Rose, newly married to surgeon Nathan Winter, wants for nothing in her perfect life–except the one thing she can’t have: for her sister, Daisy, who’s lying unresponsive in a coma, to wake up.

Daisy’s psychologist has been a constant presence at her hospital bedside. But he’s taken an unnatural interest in Rose, and now he’s made a shocking accusation: that Rose’s husband is a psychopath and that she’s in danger.

Of course, that’s ridiculous. Rose was married to a psychopath before–a man whose nature took a deadly turn after a year of wedded bliss–and Nathan is nothing like him.

Her sisters would know what to do. Only Maggie is miles away and Daisy isn’t getting any better.

As Daisy continues to fight for her life and the psychologist’s interest in Rose turns to obsession, she’s torn between the two men, each on their own twisted path and each with questionable motives.

Who should she believe?

A complete stranger consumed by obsession? Or her loving husband who’s given her everything she ever wanted?

She’s been married to Nathan for a year now. And if he is a psychopath...

Is his nature about to take a deadly turn?

Narrated by Joanne Froggatt, the beloved Anna Bates from Downton Abbey, and Louise Brealey from Sherlock...from the number one best-selling author of When He’s Not Here comes another dark and twisty psychological thriller that will linger in your mind long after you’ve finished the book.
