From the bestselling author of The Stolen Child and The Lighthouse Secret comes a gripping new novel about two abandoned sisters, a missing mother and a shocking thirty year old mystery. On a cold afternoon in December 1995, two young girls are found abandoned on a platform at Pearse Station in Dublin. Thirty years later, investigative journalist Vega is determined to find out what happened to the so-called 'Nowhere Girls'. Where did their mother go? Why did no one come forward to claim them? And where are they now? Searching for answers takes her on a journey with twists she never could have imagined. And one that could put everything else she knows at risk; including her new relationship, her career, and her life as she knows it.
