* Leviathan: The Unauthorised Biography of Sydney A RIVETING HISTORICAL BIOGRAPHY OF A REMARKABLE AUSTRALIAN CITY “Combining intensive research with the pace of a techno-thriller, John Birmingham creates a rich portrait of a city too dazzled by its own gorgeous reflection to care much for what lies at its dark, corrupted heart. … Birmingham drills beneath the cover story of a successful multicultural metropolis and melts the boundaries between past and present … Beneath the shining harbour, amid the towers of global greed and deep inside the bad-drugs madness of the suburban wastelands, lies Sydney's shadow history. … Illuminated by wild flashes of black humour, violent, ghoulish and utterly compelling, Leviathan is history for the Tarantino generation.” ISBN: 0091842034; ISBN: 9780091842031; ISBN: 0091832616
