Coventry, 1941. The morning after one of the worst nights of the Blitz. Twenty-two-year-old Rose enters the remains of a bombed house to find her best friend dead. Shocked and confused, she makes a split-second decision that will reverberate for generations to come.

More than fifty years later, in modern-day Brighton, Rose’s granddaughter Lara waits for the return of her eighteen-year-old son Jay. Reckless and idealistic, he has gone to Iraq to stand on a conflict line as an unarmed witness to peace.

Lara holds her parents, Mollie and Rufus, partly responsible for Jay’s departure. But in her attempts to explain their thwarted passions, she finds all her assumptions about her own life are called into question.

Then into this damaged family come two strangers – Oliver, a former faith healer, and Jemmy, a young woman devastated by the loss of a baby. Together they help to establish a partial peace – but at what cost?
