In the wake of the Coronavirus COVID-19 pandemic, the world learned some big lessons. But not enough. Life eventually returned to normal, affluence and profligate activity increased - it was The Best of Times. But then the gap between the Haves and the Have-Nots grew. Finally, halfway through the 21st century urban riots, drone warfare and nuclear war, followed by the Ultimate Virus, wiped out the world's population -- save a little colony on Australia's Bondi Beach, which sets about rebuilding a new world. Written before the COVID19 pandemic, in response to the conjecture of Australian Professor Huw Price, Head of the Centre for the Study of Existential Risk at Csmbridge University, that a mega virus was one of the major existential threats facing our society, this is a story of a great love affair, political intrigue, danger and heroic -- and mock- heroic -- endeavour, as well as a warning of what could be in store for us all.
