Lucy is running from what she's done - and what someone did to her.

There's only one person who might understand: her sister Jess. But when Lucy arrives at her sister's desolate cliff-top house, Jess is gone.

Lucy is now alone, in a strange town steeped in rumour. Stories of men disappearing without a trace. A foundling discovered in a sea-swept cave. And women's voices murmuring on the waves...

As Lucy searches for her sister, those voices get ever louder. They tell of two sisters, two centuries ago, bound and transported across the world. A world where men always get their way. A world that is at once distant, and achingly familiar.

Are these voices luring Lucy closer to her sister? Or will the secrets of the past pull them both under?
