Frankenstein; or, The Modern Prometheus (1818). Mary Wollstonecraft Shelley

I cannot pretend to describe what I then felt. I had before experienced sensations of horror; and I have endeavoured to bestow upon them adequate expressions, but words cannot convey an idea of the heart-sickening despair that I then endured.
"Frankenstein; or, The Modern Prometheus" (1818) tells the story of Victor Frankenstein, a young scientist who creates a sapient creature in an unorthodox scientific experiment.
