Set in the late twenty-first century, the book tells of a deadly pandemic that leaves a lone survivor, and follows his journey through a post-apocalyptic world that's devoid of humanity and reclaimed by nature. But rather than give in to despair, Shelley uses the now-ubiquitous end-times plot to imagine a new world where freshly-formed communities and alternative ways of being stand in for self-important politicians serving corrupt institutions, and where nature reigns mightily over humanity—a timely message for our current era of climate collapse and political upheaval. The novel also broaches partisan dysfunction, imperial warfare, refugee crises, and economic collapse—and brings the legacy of her radically progressive parents, William Godwin and Mary Wollstonecraft, to bear on present-day questions about making a better world less centered around “man.”
