L. Ron Hubbard was an American writer best known for science fiction and adventure fiction. He authored Battlefield Earth and Dianetics: The Modern Science of Mental Health, and also founded the Church of Scientology.
If you enjoy Hubbard’s energetic plots, larger-than-life ideas, and classic pulp-era sense of adventure, these authors are well worth exploring:
E. E. 'Doc' Smith is one of the defining names in space opera. His fiction thrives on enormous stakes, futuristic inventions, and sweeping conflicts between heroic and sinister forces.
If Hubbard’s flair for vivid, high-energy storytelling appeals to you, Smith’s The Skylark of Space is a natural next pick, delivering daring exploration, interplanetary warfare, and a boundless sense of adventure.
A. E. van Vogt is known for inventive, layered stories packed with mystery, strange powers, and unexpected turns. His novels often place capable protagonists inside unsettling conspiracies and unusual philosophical frameworks.
Readers drawn to Hubbard’s more intricate plots may enjoy van Vogt’s The World of Null-A, a mind-bending blend of futuristic science, psychology, and suspense.
Robert A. Heinlein combines page-turning adventure with big ideas. His fiction frequently explores self-reliance, civic duty, freedom, and the role of the individual in a vast and demanding universe.
If you like Hubbard’s momentum and ambition, Starship Troopers offers a gripping military science fiction story with plenty to think about long after the action ends.
Poul Anderson writes adventurous science fiction with intellectual heft. His stories often feature exploration, alien contact, and survival, all grounded in settings that feel both imaginative and scientifically credible.
If Hubbard’s adventurous spirit keeps you turning pages, Anderson’s Tau Zero is a strong choice, following a starship crew facing a crisis that grows more astonishing with every chapter.
Isaac Asimov is celebrated for clear, idea-driven science fiction that examines how technology, politics, and knowledge shape civilization. His work is often less pulp-driven than Hubbard’s, but no less compelling.
If you enjoy stories that pair grand scale with questions about human behavior, Asimov’s Foundation is an essential read about preserving culture and reason as a galactic empire begins to fall apart.
Arthur C. Clarke brings scientific rigor and awe to his fiction. His novels often contemplate humanity’s future, the mysteries of intelligence, and our small but meaningful place in the cosmos.
Those who appreciate Hubbard’s imaginative reach may want to try Clarke’s 2001: A Space Odyssey, a thoughtful and haunting journey through evolution, technology, and the unknown.
Edmond Hamilton helped shape the classic space adventure tradition with tales full of cosmic empires, dramatic battles, and far-flung worlds. His work has the same headlong, larger-than-life energy many Hubbard readers enjoy.
Fans of bold storytelling should take a look at Hamilton’s The Star Kings, a fast-moving novel in which an ordinary man is swept into political conflict and danger in a distant future galaxy.
Jack Williamson specialized in imaginative, action-heavy science fiction built around memorable concepts and strong adventure plotting. His stories frequently examine both the promise and the risk of scientific progress.
If Hubbard’s mix of excitement and big speculative ideas works for you, Williamson’s The Legion of Space delivers heroic exploits, looming threats, and old-school science fiction charm.
C. L. Moore brought a lyrical, emotional richness to science fiction and fantasy. Her stories are often atmospheric, character-focused, and tinged with danger, wonder, and unease.
Readers who like imaginative settings but also want stronger mood and psychological tension should try Moore’s Shambleau, an unforgettable story featuring Northwest Smith and one of the genre’s most haunting alien encounters.
Leigh Brackett writes with swagger, atmosphere, and a strong sense of place. Her fiction blends planetary romance, science fiction, and fantasy into stories that feel rugged, exotic, and intensely visual.
If you enjoy Hubbard’s vivid worlds and adventurous pacing, Brackett’s The Sword of Rhiannon offers ancient mysteries, perilous action, and a richly imagined Mars.
Philip José Farmer is an imaginative and often unconventional storyteller whose books mix adventure with speculative worldbuilding. He had a gift for taking wild premises and making them feel thrillingly possible.
If Hubbard’s expansive imagination appeals to you, Farmer’s To Your Scattered Bodies Go is worth picking up.
Set in a mysterious afterlife where historical figures awaken along the banks of an endless river, it offers a fresh premise, plenty of intrigue, and a strong sense of discovery.
Frank Herbert is renowned for building vast, believable worlds shaped by politics, religion, ecology, and power. His fiction is more layered and meditative than Hubbard’s, but it shares a taste for scale and ambition.
Readers who enjoy immersive settings should try Herbert’s Dune, a richly textured novel set on Arrakis, where prophecy, empire, and survival collide.
It’s a rewarding choice if you want science fiction that combines action with deeper thematic complexity.
Harry Harrison brings humor, speed, and sharp wit to science fiction adventure. His books often feature clever antiheroes, playful satire, and brisk, entertaining plots.
If you like Hubbard’s readability and sense of momentum, The Stainless Steel Rat is a fun recommendation, following master criminal turned reluctant operative Slippery Jim diGriz through one outrageous mission after another.
Keith Laumer wrote lively science fiction that balances action with humor and personality. His stories are accessible, fast-moving, and populated by characters who know how to talk their way into—or out of—trouble.
Try Retief's War, which follows diplomat Jame Retief as he navigates interstellar crises with intelligence, nerve, and a healthy disregard for bureaucracy.
Edgar Rice Burroughs is one of the great masters of classic adventure fiction. His stories are filled with daring heroes, strange civilizations, and nonstop momentum, qualities that also make Hubbard’s fiction appealing to many readers.
If you’re in the mood for a foundational planetary adventure, Burroughs’ A Princess of Mars is an excellent place to start.
It sends John Carter to Mars, where he encounters fierce battles, extraordinary creatures, and a world that helped define science fiction adventure for generations.
