Two ordinary families. One life-changing day. . .

When the Gleesons and the Stanhopes become neighbours, lonely Lena Gleeson wants a friend.

But Anne Stanhope – cold, elegant, unstable – wants to be left alone. It's left to their children – Lena's youngest, Kate, and Anne's only child, Peter – to find their way to one another. To form a friendship whose resilience and love will be almost broken by the fault line dividing both families, and a tragedy that will engulf them all. A tragedy whose true origins only become clear many years later. . .

When everything has fallen apart, can their children's love pull it back together again?
