Most of Australia's leaders since Federation believed in God. Some were serious Christians and very few were indifferent towards religion. In this timely and original book, Roy Williams examines the spiritual life of each of our Prime Ministers from Edmund Barton to Julia Gillard. He explores the ways in which - for good and ill - their beliefs (or agnosticism) shaped the history and development of the nation. Featuring extensive interviews with John Howard and Kevin Rudd, and pulling no punches, IN GOD THEY TRUST? will appeal to voters across party lines and excite plenty of debate among believers and non-believers alike.
