The first novel to move into what became science-fiction, this work by 19-year-old Mary Shelley has become a milestone in the development of the modern genre, though it is heavily influenced by Gothic and romantic modes of literature.
Frankenstein has had a huge impact on modern literature and been adapted in many forms, from the stage to the film theater. A recent adaptation by Dave Morris is available as an interactive app: http://www.inklestudios.com/frankenstein/
