In the late 1980s, two teenage girls found refuge from a world of cosy conformity, sexism and the nuclear arms race in protest and punk. Then, drawn in by a promise of meaning and purpose, they cast off their punk outfits and became born-again Christians. Unsure which fate would come first - nuclear annihilation or the Second Coming of Jesus - they sought answers from end-times evangelists, scrutinising friends and family for signs of demon possession and identifying EFTPOS and barcodes as signs of a looming apocalypse.

Fast forward to 2021, and Rebecca and Maz - now a science historian and an engineer - are on a road trip to the West Coast. Their journey, though full of laughter and conversation and hot pies, is haunted by the threats of climate change, conspiracy theories, and a massive overdue earthquake.End Times interweaves the stories of these two periods in Rebecca's life, both of which have at heart a sleepless fear of the end of the world.
