There is something almost magical about opening a book and realizing, pages later, that you are no longer exactly the same person. This silent transformation is what makes reading one of humanity’s most powerful experiences — and also what makes it so difficult to answer the question: “Which book should I read?”
The good news is that, over centuries of world literature, some works have stood out in such a way that they have transcended borders, languages, and generations. Not by decree, but because they touched on something universal: the fear of death, the search for meaning, love, injustice, curiosity about what we are. These are books that continue to be discussed in classrooms, dinner tables, and WhatsApp groups with the same intensity as when they were released.
This list does not pretend to be definitive — no such list could be. But it gathers works that, for different reasons, deserve to be on the shelf (and in the mind) of any reader who wants to better understand the world and themselves.
Literary Classics That Still Resonate
Don Quixote — Miguel de Cervantes (1605 and 1615)
Considered by many critics and writers as the first modern novel, Don Quixote tells the story of a man who reads so many chivalric books that he begins to believe he is a knight-errant. What might seem like a simple satire reveals itself, in reading, as a profound meditation on illusion, reality, idealism, and the fragility of human reason.
Published in two parts — the first in 1605 and the second in 1615 — Cervantes’ book influenced virtually all Western fiction that followed. Gabriel García Márquez declared on several occasions that Don Quixote was the work that taught him to write.
Crime and Punishment — Fyodor Dostoevsky (1866)
Originally published as a serial in the Russian magazine Russky Vestnik in 1866, Crime and Punishment follows Raskolnikov, a young student who plans and executes a murder believing himself to be above common morality. What follows is one of the most disturbing and precise explorations of guilt, human psychology, and the search for redemption ever written.
Dostoevsky wrote with an intensity that anticipated psychoanalysis by decades. Reading this book is often an uncomfortable experience — and precisely for that reason, unforgettable.
One Hundred Years of Solitude — Gabriel García Márquez (1967)
Released in 1967, the Colombian García Márquez’s novel is the founding text of what has come to be known as magical realism — a literary style where fantastic elements coexist with the everyday without causing estrangement. The saga of the Buendía family in the fictional Macondo is, at the same time, the story of Latin America, memory, time, and the repetition of human errors.
García Márquez won the Nobel Prize in Literature in 1982, and One Hundred Years of Solitude is frequently cited as one of the greatest novels of the 20th century.
Books That Changed the Way We Think About the World
1984 — George Orwell (1949)
Few books have entered the everyday vocabulary as much as 1984. Terms like “Big Brother,” “doublethink,” and “newspeak” were created by Orwell in this dystopian novel published in 1949 and today are part of the global political and journalistic lexicon.
The story of Winston Smith living in a totalitarian regime that controls not only bodies but thoughts and the very language of citizens is a work of science fiction that seems, at different moments in history, like a report.
The Lord of the Rings — J.R.R. Tolkien (1954–1955)
Published in three volumes between 1954 and 1955, Tolkien’s trilogy practically created from scratch the structure of what we now call epic fantasy. More than elves and dragons, what makes The Lord of the Rings enduring is its reflection on courage, friendship, the burden of power, and resistance in the face of evil.
Tolkien was a professor of medieval languages at the University of Oxford and constructed entire languages for his work, such as Quenya and Sindarin — Elvish languages with complete grammar and vocabulary. This level of dedication to the fictional world is rarely matched in literature.
For Those Who Want to Understand Human Nature
On the Origin of Species — Charles Darwin (1859)
It is not fiction, it is not easy in some parts, and yet On the Origin of Species is a reading that transforms the way anyone sees life on Earth. Published in 1859, Charles Darwin’s book introduced the world to the theory of evolution by natural selection — one of the most revolutionary ideas in the history of human thought.
Contrary to what many imagine, Darwin writes with clarity and even elegance. The theory can be summarized in a few sentences, but it is in the details — the birds, the turtles, the fossils — that it gains its persuasive strength.
The Power of Habit — Charles Duhigg (2012)
Published in 2012, this book by American journalist Charles Duhigg translates decades of scientific research on human behavior into accessible language. The central premise is that much of what we do daily is not the result of conscious decision, but of habits — automatic routines formed in the brain over time.
Understanding how habits work (the cue, the routine, and the reward) helps both personally and professionally. It is one of the best-selling non-fiction books of the last decades, translated into dozens of languages.
Works That Expand Scientific Horizons
A Brief History of Time — Stephen Hawking (1988)
When Stephen Hawking published A Brief History of Time in 1988, his editor said that each equation included in the book would halve sales. Hawking kept only one: E = mc². The result was one of the best-selling science books of all time, with over 10 million copies sold by the early 2000s.
The book explores black holes, the Big Bang, the nature of time, and the limits of human knowledge in a way that any curious reader can follow. For those who want to deepen their fascination with the cosmos, it is worth complementing with the article The Universe is Stranger Than You Imagine.
Sapiens: A Brief History of Humankind — Yuval Noah Harari (2011)
Originally published in Hebrew in 2011 and translated into Portuguese a few years later, Sapiens by Israeli historian Yuval Noah Harari proposes a reinterpretation of human trajectory from the first Homo sapiens in Africa to the digital era. The book’s great provocation is the thesis that what differentiates humans from other species is the ability to believe in collective fictions — money, nations, religions, companies.
It is a book that irritates some specialists for its generalizations, but it masterfully fulfills the task of making the reader question what they consider obvious.
A Practical List to Start (or Resume) Reading
If you want to build a shelf of essential works, here is a suggestion organized by reader profile:
- For those who love adventure and fantastic worlds: The Lord of the Rings (Tolkien) and Don Quixote (Cervantes)
- For those who want to understand politics and power: 1984 (Orwell) and Sapiens (Harari)
- For those seeking psychological depth: Crime and Punishment (Dostoevsky) and The Catcher in the Rye (Salinger, 1951)
- For those who want accessible science: A Brief History of Time (Hawking) and On the Origin of Species (Darwin)
- For those who love Latin American prose: One Hundred Years of Solitude (García Márquez) and The Devil to Pay in the Backlands (Guimarães Rosa, 1956)
- For personal development based on research: The Power of Habit (Duhigg)
Why Read These Books in 2026?
We live in an era of instant content, short videos, and fragmented information. It has never been so easy to consume — and so difficult to deepen. That is precisely why long, dense books that require attention have become, paradoxically, more valuable than ever.
Research in cognitive psychology indicates that reading fiction, in particular, is associated with the development of empathy — the ability to imagine another’s perspective. Meanwhile, reading scientific and philosophical non-fiction stimulates critical thinking and tolerance for uncertainty, skills increasingly necessary in a complex world.
Just as documentaries can be a gateway to new knowledge, good books function as windows to other times, minds, and realities — without leaving the couch.
Conclusion: The Right Book at the Right Time
There is no single list of books that everyone must read — and anyone who claims otherwise has probably never finished reading even half of them. What exists are works that, over time, have proven to have something to say to very different readers, in very different contexts.
The best approach is to start with what genuinely sparks curiosity. A reader who finishes an epic fantasy book with shining eyes has done something much more important than someone who dragged through a classic out of obligation. Reading, above all, is a pleasure — and pleasure cannot be forced.
What these books have in common, at the core, is the ability to ask good questions. And good questions, as any experienced reader knows, are worth more than ready-made answers.
