Mary Shelley's Frankenstein is definitely my answer. Let's say I'm not a regular reader, but when I read and finish reading a book it's because it has to captivate me and have real literary value.

Shelley tells with true genius a story that could promise a breakthrough for science, although it is not my intention to spoiler and thus invite other readers to include it in their library, I will make a brief synopsis of what most attracted me to this book.

Victor in his thirst to give life, believing he has that power which many attribute or attribute to a supreme God, ends up creating an abominable creature, which after its arrival to life only provokes repulsion. The monster was apparently not simply living organic matter but even possessed human feelings who, feeling despised by his creator, decided to turn his life into an agony.

I hope you are encouraged to read this fabulous story if you haven't already done so and although I would love to talk to you about its outcome, I'll keep my comments to myself and in some publication we can open a good debate about this fantastic literary work.
