The birth of the gothic narrative was arguably bolstered by Shelley's 'Frankenstein'. Simply philosophically engaging when one considers how at its core is the question of whether the evil that's prevalent in the world was manufactured by inhumanity.
We read it for the Southern African English Olympiad this year (2016) where we explored the leitmotif: The Darkness in Man's Heart.
p.s: I especial love the archaic diction - palatable.
There is a lot to be said about this novel, that could not possibly be fully exposed in a few words. The horror of the story is conveyed by a series of narrators. Each narration brings forth the feelings and the need of creating a full opinion based on different perspectives. The laughter, the infernal laughter of the creation and Frankenstein's deed are brought in all its horror. But, moreover, the monster is society, that segregates, discriminates and casts people away by aribitrary norms.
