The War of the Worlds (Penguin Classics)

The night after a shooting star is seen streaking through the sky from Mars, a cylinder is discovered on Horsell Common in London. At first, naive locals approach the cylinder armed just with a white flag only to be quickly killed by an all-destroying heat-ray, as terrifying tentacled invaders emerge. Soon the whole of human civilisation is under threat, as powerful Martians 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.

This is the granddaddy of all alien invasion stories, first published by H.G. Wells in 1898. The novel begins ominously, as the lone voice of a narrator tells readers that "No one would have believed in the last years of the nineteenth century that this world was being watched keenly and closely by intelligences greater than man's..."

Things then progress from a series of seemingly mundane reports about odd atmospheric disturbances taking place on Mars to the arrival of Martians just outside of London. At first the Martians seem laughable, hardly able to move in Earth's comparatively heavy gravity even enough to raise themselves out of the pit created when their spaceship landed. But soon the Martians reveal their true nature as death machines 100-feet tall rise up from the pit and begin laying waste to the surrounding land. Wells quickly moves the story from the countryside to the evacuation of London itself and the loss of all hope as England's military suffers defeat after defeat. With horror his narrator describes how the Martians suck the blood from living humans for sustenance, and how it's clear that man is not being conquered so much a corralled. --Craig E. Engler
