I Am Legend - Richard Matheson

GoodReads Summary: Robert Neville is the last living man on Earth... but he is not alone. Every other man, woman and child on the planet has become a vampire, and they are hungry for Neville's blood.

By day he is the hunter, stalking the undead through the ruins of civilisation. By night, he barricades himself in his home and prays for the dawn.

Sadly, a lot of people may be driven away from the book due the movie -- which follows a very simple plot line.

But the book does not have a simple plot line. It is complex, twisting and its purpose only shows in the very last line. In that line, the whole story finally clicks; all plots and twists, all descriptions and names, everything clicks. And you stay there, suddenly hit by its plot like a brick hitting you in the side of your face.
