Max didn’t believe in an afterlife. Until he died. Now, as a reluctant ghost trying to work out why he is still here, he watches his girlfriend, Hannah, lost in grief in the apartment they shared and begins to realize how much of her life was invisible to him. In the weeks and months before Max’s death, Hannah was haunted by the secrets she left Australia to escape. A relationship with Max seemed to offer the potential of a fresh new chapter, but the past refused to stay hidden. It found expression in the untold stories of the people she grew up with, and the events that broke her family apart and led her to Max.

Surging out of the sea, the Bass Rock has always borne witness to the lives that pass under its shadow on the Scottish mainland. And across the centuries, the fates of three women are inextricably linked to this place and to one another. Sarah, accused of being a witch, is fleeing for her life; Ruth, in the aftermath of the Second World War, is navigating a new marriage and the strange waters of the local community; and six decades later, Viv, still mourning the death of her father, is cataloging Ruth's belongings in the now-empty house. As each woman's story unfolds, it becomes increasingly clear that their choices are circumscribed, in ways big and small, by the men who seek to control them. But in sisterhood there is also the possibility of survival and a new way of life.
