These excerpts from Alex Scarrow's "Last Light" introduce a post-apocalyptic narrative where global society collapses due to a sudden and severe oil crisis. The story follows multiple characters, including Andy, a consultant whose past report on oil vulnerabilities becomes eerily relevant, and his family, Jenny, Leona, and Jacob, as they navigate the escalating chaos. The events unfold across various locations like Iraq amidst military withdrawal, and London, which rapidly descends into anarchy with power outages, food shortages, and rampant looting. The government attempts to establish "safe zones" and rationing, but these efforts prove insufficient as the crisis leads to widespread societal breakdown and the rise of dangerous elements like the "Bad Boys" gang. Ultimately, the excerpts highlight the fragility of modern civilization when its foundational resource is disrupted, portraying a world grappling with survival and the disintegration of order.
