Set in the year 2457, on the outskirts of Melbourne, Australia, a crime committed by two young Norwegians affects the entire community living at the base of the Dandenong Ranges. If caught, Yngwie and his friend Torleif, who are expert communication systems hackers, must answer to the Federation Special Investigation Unit. Others who use the event as inspiration plunge the forests and its people into chaos. The lives of scientists, forest guardians and seed gatherers are placed at risk, as are their cats – extraordinary creatures bred in special centres and with the power to influence human emotions.

In this third book of the series, that began with ‘The Cicada’, followed by ‘A Death In The Making’, the story gradually links back to earlier, unresolved questions. It also continues to explore the relationship between the cats and their human companions. When the geneticists at the breeding centre in Werribee realise the cats can perhaps no longer be controlled, they are faced with an ethical dilemma. Similarly, after a new and intriguing forest inhabitant is discovered, those who know of its existence must decide whether to reveal its secret.

By the year 2050, the world’s population had reached ten billion, and by 2090, had risen to twelve billion. Finally, by 2135, with a population of fifteen billion, Earth was in a state of crisis. Species extinctions increased exponentially and the planet’s ecosystems were at breaking point. The sick, the frail, the prematurely born and the disabled could no longer gain access to dwindling medical supplies and overextended facilities, so died in their hundreds of millions. Life expectancy dropped to a meagre fifty-six years in even the least affected countries.

As the world’s climate became increasingly unstable, and the wealthier nations began to feel the direst impacts, an awareness of the need for global government developed. The United Nations Assembly was transformed into the World Federation of Nations. Economic and technological aid, together with political incentives, were offered to those countries unable, or unwilling, to introduce population control or effective resource conservation measures. Some resisted what they perceived as interference and closed their borders, nationalising foreign-owned industries in a vain attempt to exclude the outside world. Others saw themselves as powerful enough to defy both the Federation and the inevitable consequences of their actions, so declared war – and solved their population problems by losing. Yet, by the middle of the twenty-third century, the world was finally at peace, although by this time had lost most of its natural forests and other wild places, while humans now numbered a mere three billion.

What types of vehicles, animals, technology, etc. are used for travel?

The ancient centres of inner London, Stockholm, Copenhagen and Amsterdam were now ghostly ruins, surrounded by water and inhabited by shadows, while the newer, and yet still relatively old, cities of Vancouver, Miami and New Orleans had been destroyed by the unleashed violence of tidal waves. The tidal waves followed a worldwide series of massive earthquakes, during which Japan and the American state of California were destroyed, together with countless other vulnerable regions and low-lying island states.

Melbourne was more fortunate than many other coastal cities, being sheltered from the worst storms by Port Phillip Bay. Some of the older buildings in the central area were lost, but those which had been well built, or were strategically placed on the summits of low hills, survived as islands in a shallow and gentle sea. The noise, smell and dirt of the city’s streets were, in time, replaced by the grace and silence of solar-electric powered watercraft. The walls of the buildings, once covered in grime from exhaust fumes, returned to their original colours, and after almost two hundred years, the sunlight now sparkled on clean waters.
