What are the all time best selling sci fi novels?

One of the best selling sci - fi novels is 'Dune' by Frank Herbert. It has a complex and immersive world, with political intrigue, unique ecosystems, and a deep exploration of human nature in a far - future setting.

Well, 'Ender's Game' by Orson Scott Card is a best - selling sci fi novel. It tells the story of a young boy, Ender, who is trained to fight in a future inter - species war. The book delves deep into themes like morality, leadership, and the nature of war. Then there's 'Foundation' by Isaac Asimov. It's a classic that deals with a vast galactic empire on the verge of collapse and a group's attempts to shorten the coming dark age. It's known for its grand scale and scientific concepts.

Another one is '1984' by George Orwell, although it can be considered more of a dystopian sci - fi. It paints a terrifying picture of a totalitarian future where the government has extreme control over every aspect of people's lives. It has been highly influential in literature and discussions about society and freedom.

Some of the best include 'Star Wars'. It created a vast and immersive universe with unique species, technologies, and the iconic Force concept. 'Blade Runner' is also great. It explores what it means to be human in a future filled with replicants. And 'The Matrix' which introduced mind - bending ideas about reality and virtual worlds.

I really love 'Ender's Game' by Orson Scott Card. It's a story about a young boy, Ender, who is trained to fight in a war against an alien race. The psychological depth of the characters and the exploration of morality in war are fascinating. 'Foundation' by Isaac Asimov is also among my favorites. It presents an epic view of a galactic empire in decline and the efforts to preserve knowledge. And then there's 'Brave New World' by Aldous Huxley. It shows a future society where people are conditioned from birth, which makes you think about freedom and individuality.

For beginners, 'Fahrenheit 451' by Ray Bradbury is excellent. It's not too complex in terms of sci - fi concepts but has a really powerful message about censorship and the importance of books. Also, 'A Wrinkle in Time' by Madeleine L'Engle is a good start. It's a story about time travel and fighting against an evil force, and it has a very imaginative and magical feel to it.

The way the environment is described makes it seem like a place that's both beautiful and terrifying at the same time. Another good one was 'The Calculating Stars' by Mary Robinette Kowal.
