In the Days of the Comet (Unabridged) [Unabridged Fiction‪]‬

A comet speeds toward earth, a deadly, glowing orb that soon fills the sky and promises doom. But mankind is too consumed with greed and violence to care. As luminous green trails of cosmic dust and vapor stream across the heavens, blood flows beneath: nations wage all-out war, bitter strikes erupt, and jealous lovers plot revenge and murder. The Earth slips past the comet by the narrowest of margins, but all succumb to the gases in its tail. When mankind wakes up, everyone is completely and profoundly different.
In the Days of the Comet is H. G. Wells' classic tale of the last days of the old Earth and the extraterrestrial change that becomes the salvation of the human race.
