In six sentences
Frankenstein, in our own words.
- Frankenstein is less a monster story than a book about responsibility, asking what a creator owes the living being he makes and then refuses to love.
- It is built like a set of nested boxes, with an explorer's letters to his sister framing Victor Frankenstein's confession, which in turn frames the creature's own account of his life.
- The central tension runs between Victor's hunger for discovery and his horror at what he has made, a gap that leaves his creation abandoned, articulate and increasingly bitter.
- Shelley keeps returning to loneliness and exclusion, showing how a mind that begins open and eager is shaped by the way other people react to its appearance.
- Our sentiment arc starts bright in the letters and the Geneva childhood, then drops below zero in 14 of its 40 slices, the most of any book on this site.
- Begun as a ghost story during a cold, rainy summer near Geneva, it still shapes how we argue about science and ambition, and its creature remains one of fiction's most eloquent outsiders.
Where and when
Geneva, the university town of Ingolstadt, the Alps, Britain, Ireland and the Arctic, in the 1700s (the opening letters are dated 17—).

We split the novel into 40 equal slices of about 1,800 words and score each by the average VADER sentiment of its sentences, from −1 (most negative) to +1 (most positive); the line is a five-slice moving average, and the dotted line is neutral. Computed from the 1818 text, which runs in three volumes after four opening letters. It measures the tone of the words, not what happens.

This chart counts how often five central characters are named in each twentieth of the book, about 3,600 words, including nicknames and titles such as Henry for Clerval. The creature has no name, so we count the words others use for him, such as monster, fiend and dæmon, and Victor looks quiet because he narrates most of the book as I.

Lines join the eight most-named characters, and a thicker line means more paragraphs that name both of them; pairs named together in fewer than three paragraphs are left out. Felix and Safie, from the cottage the creature watches, connect mainly to each other.
