The happiest and saddest classic novels, chapter by chapter.
Score the mood of every sentence in 136 classic novels and average it chapter by chapter, and the averages turn out to be the dull part. The interesting books are the ones that change: bright for a hundred pages, then somewhere else entirely.
Every strip on this page is a real Books strip from the Huezle app, drawn by the app’s own code. More about Books.
How to read the strips
Each strip is one novel, from the opening on the left to the ending on the right. Each band is one chapter, or one of 24 equal sections where a book’s chapter headings could not be found reliably. Deep indigo means the writing in that stretch is sombre, warm grey means even, and gold means bright.
Mood is measured with VADER, a standard tool that scores a sentence by its words: “grief” and “dead” pull it down, “love” and “dear” lift it. The scale is relative to these 136 books, and the middle grey sits at the median chapter, which scores slightly positive.
What VADER cannot do. It reads words, not meaning, so it misses irony and cannot tell a happy scene told in sad words from the other way round. Read a strip as the tone of the vocabulary, not a verdict on the plot.
The darkest and the brightest
Only eleven of the 136 average below zero at all. The darkest is Zola’s Germinal, his novel of a mining strike, and it gets darker as it goes: every one of its last sixteen chapters scores below zero.
- Sombre
- Even
- Bright
Little Women is the brightest book in the set by a clear margin, averaging +0.254 against the median chapter’s +0.067. About thirty of its 47 chapters reach full gold, not one is sombre, and it brightens as it goes: its last quarter is the brightest stretch of any book here.
- Sombre
- Even
- Bright
The books that fall apart
Frankenstein has the steepest fall in the set. Its first quarter averages +0.232, close to Little Women, and its last quarter −0.008, with the darkest chapter of the book second from the end. Its average is unremarkable; its shape is not.
- Sombre
- Even
- Bright
Thérèse Raquin, Zola again, swings the furthest. Its brightest chapter, the eighth, is gold; from chapter 14 on it holds four of the five darkest chapters in all 136 novels, including the single darkest, chapter 22.
- Sombre
- Even
- Bright
The Strange Case of Dr. Jekyll and Mr. Hyde averages almost exactly zero, which hides a strip that saves its darkest section for the very last of its 24.
- Sombre
- Even
- Bright
Shelves have moods too
The books are split into six collections, and in the app the three wrong answers always come from the same one. Gothic & mystery is the gloomiest shelf on average, which is no surprise, but its brightest book is Frankenstein, which says as much about that first quarter as about the genre. The English novel and the children’s classics are the brightest. For a seasonal pick from the darker shelf, see gothic novels for Halloween.
The other 131 novels are puzzles in the Books category. For other strips read left to right through one work, see the colours of famous album covers or the best TV seasons of all time.
Huezle shows you one of these strips and four titles from the same shelf. See if you can tell a book that falls apart from one that never lifts.

By average mood across its chapters, Émile Zola’s Germinal, by a whisker. The single darkest chapter in the 136 books is chapter 22 of Zola’s Thérèse Raquin.
What is the happiest classic novel?
Little Women, by a clear margin. About thirty of its 47 chapters score bright enough to reach the top of the scale, and none is sombre.
How is the mood of a book measured?
Every sentence is scored with VADER, a word-based sentiment tool, and the scores are averaged chapter by chapter. It measures the tone of the vocabulary, so it can miss irony.
