In 2003, Marina Cantacuzino, an award-winning journalist, set off on a quest to interview people who had lived through violence, tragedy, or injustice and still practiced forgiveness rather than revenge. Using real stories from a variety of settings, she aimed to help others discern the full weight of forgiveness, reconciliation, and conflict transformation.

The people interviewed on these pages include both survivors and perpetrators of crime and violence. In her introduction, Cantacuzino notes: "If forgiveness was a colour, for me it would be grey, the colour of compromise and conciliation, and because it sits between the two extremes of black and white."

In 2004, Cantacuzino founded The Forgiveness Project, a UK Charity and not-for-profit organization to advance the cause of reconciliation and conflict resolution. Archbishop Desmond Tutu was a founding patron of this organization along with human rights activist Anita Roddick. Tutu has said of the Forgiveness Project that it "has shown us that true greatness is found in humility and compassion." As one of its activities, the organization has shown "The F Word" exhibition to 70,000 people around the globe. In 2012, Cantacuzino spoke at the UN General Assembly about the work of The Forgiveness Project.
