Once upon a time Gabrielle Price wrote and published an extraordinary novel. But 20 years on her literary star has dimmed, her "work of genius" is all but forgotten, and no further novels have materialised. 

She now lives an unremarkable life: middle-aged, living alone in the sleepy village she grew up in, and working as a housekeeper for the local vicar. Her lonely existence is dominated by memories of her best friend Madeleine, who died young, in tragic and mysterious circumstances. 

Gabrielle’s quiet world is turned upside down when she meets and befriends Simon - young, attractive, a would-be writer, and enthusiastic fan of the astonishing novel that Gabrielle published all those years ago. 

Charmed and flattered, she recklessly invites him into her home and her heart. But Simon is mysterious and manipulative, and it’s not long before he forces Gabrielle to confront the demons in her past. 

Gabrielle’s obsession begins to destroy her carefully cultivated life, and she comes to feel increasingly threatened by Simon’s presence. 

Who is he? Why did he seek her out? And what does he really want?
