- In his Author’s Preface, Cooper gives an overview of this highly detailed account of events surrounding the Bougainville copper mining crisis of 1969. He states: "I set out the background to the Rorovana land crisis, and explore the part people connected with Moral Re-Armament played in effecting a solution to it. I do not attempt to give a complete history of the mining operation, nor to evaluate other parties’ roles in the dispute - Bougainville nationalists, Australian MPS, academics, journalists, unionists and the Catholic Church also played their parts."
