After Morgan Wells's wife leaves him, a postcard from France arrives. It is addressed to a Morgan Wells - but not the Morgan Wells who receives it. Desperate to be led out of his despair, Morgan decides to read the postcard as a sign and embark upon a surreal journey to find, observe, and meet the other Morgan Wellses in the city of Toronto. On the day that a 2003 citywide power outage submerges Toronto in darkness, a teenage boy finds a missive of his own: a copy of Margaret Cavendish's The Blazing World, one of the first science fiction novels ever written. The boy, obsessed with the Choose Your Own Adventure series, interprets the coincidence of finding the book during the blackout as a premonition, and begins looking for proof that the end of the world is near. A Description of the Blazing World interlaces two narratives in a novel about the city in the new millennium: a crowded space that incubates signs of an apocalypse that never quite materializes. But it is this very threat of imminent danger - that everything could go up in blazes- that drives a reclusive man and a lonely boy to search for their respective revelations.
