Someone is watching her. She just doesn't know it yet.

Nell Sweeney has led an ordinary life. Every day she walks to and from the hospital where she works as a nurse, believing that no harm can befall her.

Until one day she is taken.

Because someone out there has a secret. Someone out there has been watching Nell - and they've been watching others like her too.

Nell is the unlucky one - she was in the wrong place at the wrong time. And if she isn't found soon, someone will make sure that she isn't the last woman to disappear...

A chilling, gripping read, perfect for fans of Clare Mackintosh and Gillian McAllister.
