Once a home full of love, all that remains in Greyfriars House are secrets and lies . . .

On a remote Scottish island sits Greyfriars House, a house haunted by unspoken words and family mysteries. But once it was a happy and comforting place and in the summer of 1939, family and friends gather to forget their fears about the impending war. Nine-year-old Olivia watches the grown-ups with fascination particularly her mother and her two aunts, the three daughters of the family who own the island. Then Olivia she sees something she isn't meant to and when the truth comes out it reverberates through the generations.

Almost fifty years later, Olivia has fallen ill and urges her own daughter, Charlotte, to visit Greyfriars to reconnect the existing branches of the family. Charlotte is hesitant to get to know her great-aunts, women who have always shunned her mother, but curiosity and a desire to run from her own life get the better of her and she goes to the island.

But Greyfriars House is a shadow of its former self and Charlotte finds her great-aunts tense and cautious. There is something they want to share with Charlotte, but in order to truly understand their secret Charlotte must first understand what happened to them before and during the war . . .
