Cat's Cradle

Chapter-by-chapter summary

Spoiler warning: this section covers the whole plot, including the ending. The book has 127 very short chapters, so they are grouped here into eight parts.

Part 1: A book about the day the world ended

The narrator, who tells us to call him Jonah, plans a book about the day the atom bomb fell on Hiroshima. He writes to people who knew Felix Hoenikker, one of the bomb's scientists, and visits the research laboratory where Hoenikker worked. Dr. Asa Breed describes a man who chased puzzles out of pure curiosity and never asked what they were for. Hoenikker's youngest son remembers his father playing with a loop of string on the day of Hiroshima. This sets up the book's first big question: what happens when brilliant people do not ask what their work will do?

Part 2: The family and ice-nine

Jonah meets two of Hoenikker's children, Angela and Newt, in the town of Ilium. They are lonely, odd adults who grew up around a father who barely noticed them. They tell him about ice-nine, a form of water that is solid at room temperature and turns any liquid water it touches into more ice-nine. Hoenikker had a piece of it when he died, and Angela, Frank and Newt each took a chip of it away in a thermos flask. This is the novel's ticking bomb, and the family's carelessness with it shows that the danger is ordinary people, not villains.

Part 3: Off to San Lorenzo

A magazine job sends Jonah to the Caribbean republic of San Lorenzo to write about the famous jungle hospital of Julian Castle. On the plane he meets the new American ambassador, Horlick Minton, and a bicycle maker, H. Lowe Crosby. He learns that Frank Hoenikker, the middle child, is now an important official there, and he first hears of Bokononism, a forbidden religion. The new religion comes with its own words, such as karass and foma, and gives the story its strange comic voice.

Part 4: A law against the only comfort

San Lorenzo is poor, hungry and run by a dictator called Papa Monzano. Practising Bokononism is punishable by death on the hook, yet nearly everyone practises it. Jonah learns that Bokonon and his friend Earl McCabe once washed up there and planned a better society, then made the religion illegal so that it would feel exciting and give the poor hope. Jonah also meets Mona, Papa's adopted daughter, and falls in love. The chapters show how a useful lie can hold a hopeless place together.

Part 5: An offer of power

Frank, who has the title Minister of Science and Progress, tells Jonah that Papa is dying and offers him the presidency. Jonah accepts once he is promised Mona as his bride. In the same stretch he sees the island's grim reality and the shabby flag-waving of its official ceremonies. The offer is a sour joke: power on San Lorenzo is a job nobody sensible wants, handed out almost at random, which echoes how carelessly the world treats the most dangerous things.

Part 6: The Hundred Martyrs to Democracy and the end of the sea

Papa Monzano, dying, swallows ice-nine and his body turns solid. Frank admits that he gave Papa his own piece of it, and he and Jonah cover up the body. Next comes the ceremony for the Hundred Martyrs to Democracy. Ambassador Minton sets aside his prepared words and attacks the kind of patriotism that glorifies war dead. During the flight display that follows, a plane catches fire and crashes into the rocks above the palace. The castle breaks apart and falls into the sea, carrying Papa's frozen body with it, and the Mintons die. The sea freezes, then the rivers and the rain. One accident ends the world's water, and the book never raises its voice.

Part 7: The survivors

Jonah and Mona survive in a bomb shelter under Papa's palace. When they climb out after days of storms, the world is frozen and almost everyone is dead. On Mount McCabe they find San Lorenzans who killed themselves by touching ice-nine to their lips, following Bokonon's advice. Mona does the same. Later H. Lowe Crosby, his wife Hazel and Newt find Jonah, and the survivors, including Frank, live together for about six months while Jonah writes the book we are reading. The scene is quiet rather than loud, which makes it hit harder.

Part 8: Bokonon at the end

Jonah sees Bokonon on a rock, writing the last page of his books. Bokonon says that if he were younger he would write a history of human stupidity, lie on top of the mountain with the book as a pillow, thumb his nose at God and die. The last mood is dark and funny at once, and it leaves us with the idea that humans are small, foolish and still worth a joke.

Characters

The narrator (Jonah, or John)

A writer who tells the story in the first person. He is curious, easy-going and a Bokononist by the end. He wants to write about Hoenikker and instead lives through the disaster.

Felix Hoenikker

A famous physicist, one of the makers of the atom bomb. He is gentle, distracted and absorbed in puzzles, and he never accepts responsibility for what his inventions do. He is dead before the story starts but shapes everything.

Angela Hoenikker

Felix's tall, unhappy daughter, who was made to take care of the household after her mother died. She marries badly and is obedient to the end.

Newt Hoenikker

The youngest son, a very small man with a sharp, bitter sense of humour. He remembers his father with the string and gives Jonah some of the clearest information about ice-nine.

Frank Hoenikker

The middle son, an inventor and a quiet, nervous man who becomes a leader in San Lorenzo. He wins his place as Papa's successor by giving Papa a piece of his ice-nine, and later helps Jonah cover up Papa's frozen body.

Bokonon

The founder of Bokononism, a gentle, funny old man who writes calypsos and hides in the jungle. He admits his religion is made of lies, and he uses it to make people brave and kind.

Papa Monzano

The dictator of San Lorenzo, a fearful man who rules with violence. Dying of illness, he swallows the ice-nine Frank gave him, and his frozen body falls into the sea with the collapsing castle, which sets off the end of the world.

Mona Aamons Monzano

Papa's adopted daughter, serene and loved by almost everyone. She is a devoted Bokononist and teaches Jonah its customs. She is the book's kindest, most hopeful character.

Julian Castle

A wealthy former playboy who now runs a hospital in the jungle. He is wry and tired, and he sees clearly that his good work cannot fix the island's real problems.

Writing about this book

The most useful way into Cat's Cradle is to choose one question and test it against a scene. You could ask whether Bokonon is right to lie to help people. Or you could ask who is to blame for ice-nine: Felix, his children, Papa Monzano or the governments that wanted weapons. A third idea is the title itself. The cat's cradle is a game in which there is no cat and no cradle, only a tangle of string, and the book suggests that many human beliefs work in the same way.

Pick one scene as evidence, such as the dying Papa, the Hoenikker children or the final talk with Bokonon, and say clearly what it shows. Then explain whether you agree with the book's view. Remember that the narrator is funny but not always reliable, so check which opinions come from Vonnegut's characters and which come from the story itself. A strong answer compares the book's jokes with the facts of the nuclear age, rather than treating it as only a joke book.
