It is Easter 2013 and Justine is running for her life. Escaping a city and a man that have between them almost broken her, she heads north, to the mountains and valleys of the Scottish Highlands where she hopes to hide and survive.
Michael and Hannah are running too. Gathering together their two young sons and the tatters of their marriage, they have come to the remote village of Kilmacarra, a place of standing stones and threatened windfarms - a place where they hope to once again make a home.
But it is not so easy to flee one's ghosts or to find the way back once you have veered off course.
In this ancient landscape, in a country balanced on the brink of change, Justine, Michael, and Hannah are brought together by a shocking accident that entangles them all in threads of guilt and love, duty and forgiveness.
And as the ground beneath their feet begins to yield up its secrets, and each must question where they truly belong, the darkness that Justine left behind seeks her out - with perilous consequences for them all.
