The Call of Cthulhu

Short but a duly impactful and iconic story. By today's standards, The Call of Cthulhu probably wouldn't be considered remotely scary - except in how dense the writing is compared to contemporary horror - but it's still such a great study in cosmic horror. I like to call it the fear of the vast unknown.

The writing style might not be for everyone but if you're able to stomach it, I strongly recommend it for just about anybody who loves fantasy, sci-fi, and the idea of being tiny and insignificant in a vast and unknowable universe.

The most merciful thing in the world, I think, is the inability of the human mind to correlate all its contents. We live on a placid island of ignorance in the midst of black seas of infinity, and it was not meant that we should voyage far. The sciences, each straining in its own direction, have hitherto harmed us little; but some day the piecing together of dissociated knowledge will open up such terrifying vistas of reality, and of our frightful position therein, that we shall either go mad from the revelation or flee from the deadly light into the peace and safety of a new dark age.
