When the United States collapses into post-apocalyptic ruin, The Woman flees her suburban home. Chronicling her life from the first shock to building and ruling a dieselpunk fiefdom, her mind deteriorates, and she obtains a nuclear weapon. One hundred years later, a boy feeds her journals to an AI to answer lingering questions about his heritage. When the AI becomes sentient, weaving its own stories about The Woman and what her final moments might have been, the boy must confront a deranged power just like the person it was created to emulate. Told through journal entries, Cataclysm is a story of how unrepentant rage permeates generations.
