A screenwriter living in the Hollywood Hills gets advance warning of a coming disaster, a nanopathogen that renders oil supplies useless. Thinking itself a little mad, he nevertheless stocks up on supplies such as canned food and water. Pretty soon there are gas shortages, and it is clear that society is slowly unraveling while the government is hiding the truth. Things get worse and the small hill community where our hero lives buttons up, barricading the access road to prevent refugees from coming in. Then a massive Earthquake brought on by the destruction of the Los Angeles oil fields hits. Fire, flood and anarchy ensue.
Unlike many post-apocalyptic stories, this one isn’t about a superbly prepared person or group. Our hero is simply a normal person, and he does make mistakes. Varley’s skill at bringing characters to life really shines in this book. The struggle is personal, and those with real power are far away, unknowable, and untrustworthy. The big moral of the story is of course how very dependent the world is on oil. What would happen if all the oil reserves in the world vanished within the space of a few weeks? Society would break down very quickly, especially in big cities dependent on cars like Los Angeles.
