Every chart below is computed straight from the source text: Thoughts of an Eaten Sun (a grimdark fantasy novel), Genny (a near-future novella), and the published essays of my old blog, Sundered Peak. Word counts, sentence rhythm, character presence, and the made-up words left over when you subtract the English.
Each measure over normalized book progress, so an 81K-word novel and a 23K-word novella can share an axis.
Log-odds over the two vocabularies: the words that most mark each book as itself.
Subtract every word English knows (plus its inflections) and this is the residue: the coined vocabulary of each book, separated from proper names. Hover a word for where it first appears.
