This web of characters struggle, both individually and collectively, through a time of unprecedented, escalating change. Beginning in 2016, Arne Bakke witnesses the historic devastation of that summer's bushfires across the ancient wilderness of Tasmania. Elsewhere, Londoner Evie Weatherall witnesses extreme climate events in her travels. They each see a dangerous future forming. When their paths collide in Melbourne, Australia, where they are both enrolled in a PhD, they and their group of close friends are set on course to witness and struggle together against the coming century, an age of great individual and planetary loss.

Children of Tomorrow depicts an all-too-real future history, rushing on at an unstoppable speed and fracturing the lives of its many characters, the effects of which ripple throughout subsequent generations and the earth they inherit.
