H. G. Wells 
The War of the Worlds 

“The classic tale of alien invasion, and still the best“ The Times
The first modern depiction of extra-terrestrials attacking the earth, The War of the Worlds remains one of the most influential of all science-fiction works. It shows the whole of human civilization under threat, as terrifying, tentacled Martians land in England, build gigantic killing machines, destroy all in their path with black gas and burning rays and feast on the warm blood of trapped, still-living human prey. The forces of the Earth, however, may prove harder to beat than they at first appear.
