Invasion of the Body Snatchers

First published in 1955, 'Invasion of the Body Snatchers' is a science fiction horror novel set in the small town of Mill Valley, California.

The story follows Dr. Miles Bennell as he discovers that alien life-forms are taking over the bodies and minds of his neighbors, friends, and family by replacing them with perfect physical duplicates devoid of human emotion.

The novel explores the ultimate alien invasion and the human spirit's resistance against an invisible enemy.

Unlike some of its film adaptations, the novel ends on an optimistic note with the aliens leaving Earth due to the strong resistance they encounter.
