In the Days of the Comet is a 1906 science fiction book written by H. G. Wells, about the effects of a comet entering the earth's atmosphere. This event brings about a great change in humanity, and one for the good, as people see the beauty of the world and in turn become more loving and generous to their fellow humans. In the background of this, is the story of Willie Leadford; an initially angry young man with plans of destruction after his lover rejects him in favour of someone richer. The book ends with an endorsement of polyamourous relationships; a fact that didn't go down too well with Wells' peers.
