Science fiction can examine artificial intelligence, alien contact, social change and humanity’s future without becoming a demanding technical read. These eight books combine big ideas with sharp humour, strange characters and plenty of adventure.
From a starship crew trapped in a television-style universe to an alien game show contestant and a cat dragged into an intergalactic dungeon, this selection offers approachable science fiction for readers who want their ideas served with fun.

1. Redshirts by John Scalzi (2012)
John Scalzi’s Hugo Award-winning novel follows a group of new ensigns aboard a starship where away missions have an unusually high death rate. As the crew investigates the pattern behind its dangerous encounters with hostile aliens, the explanation becomes increasingly strange.
Scalzi is well known for comic science fiction, including Starter Villain and short stories adapted into episodes of the Netflix anthology Love, Death & Robots. Fans of Star Trek: Lower Decks should find plenty to enjoy in this playful examination of science-fiction conventions.
2. The Long Way to a Small, Angry Planet by Becky Chambers (2014)
Becky Chambers’ self-published debut is a character-driven journey through space. Rosemary Harper, a woman from Mars hoping to escape her past, joins a crew that creates wormholes through the galaxy.
The destination matters less than the relationships formed along the way. Rosemary’s new companions include a memorable group of aliens who protect one another, giving the novel a warm found-family atmosphere that should appeal to fans of Firefly and Farscape.
3. Artificial Condition by Martha Wells (2018)
The second book in Martha Wells’ Murderbot Diaries follows a rogue cyborg security unit that would much rather watch soap operas than manage vulnerable humans. Murderbot’s dry internal commentary supplies much of the comedy.
Its investigation into the past becomes more complicated when it encounters an advanced ship AI named Asshole Research Transport. The unlikely companion wants to share television time while Murderbot tries to understand what happened before. The Apple TV adaptation’s second season was in development at the time of the source material.
4. Space Opera by Catherynne M. Valente (2018)
In Catherynne M. Valente’s exuberant space opera, humanity must compete in the Metagalactic Grand Prix, a Eurovision-style interstellar song contest. The result is an extravagant, absurdist adventure with the energy of glam rock and the irreverence of The Hitchhiker’s Guide to the Galaxy.
Washed-up musician Decibel Jones and the Absolute Zeroes must prove that humans are sentient through music. Finishing last would mean the destruction of the entire species.
5. Chilling Effect by Valerie Valdes (2019)
Valerie Valdes gives the space-opera crew an especially unruly mission. Captain Eva Innocente is trying to rescue her kidnapped sister, but she hides the full situation from her crew while taking dangerous jobs to raise the ransom.
La Sirena Negra’s adventures include psychic cats, an alien emperor’s unwanted affection and plenty of foul-mouthed humour. The novel also takes aim at video-game conventions and pop culture while keeping its central rescue mission moving.
6. Gideon the Ninth by Tamsyn Muir (2019)
Tamsyn Muir’s first Locked Tomb novel combines science fantasy, necromancy and a bloody mystery. Gideon must protect the necromancer Harrow while heirs from the empire’s great houses face trials intended to prove their worthiness for immortality.
Gideon’s sarcastic attitude prevents the grim setting from becoming relentlessly bleak. With skull makeup, aviator sunglasses and an enduring talent for irritating Harrow, she must help solve a series of murders before the remaining competitors become the next victims.
7. Project Hail Mary by Andy Weir (2021)
Andy Weir follows The Martian with another science-heavy survival adventure, this time shaped as an unlikely buddy story. Ryland Grace, a science teacher and biologist, wakes with amnesia aboard a spacecraft orbiting a distant star.
He soon learns that he is the sole survivor of a mission designed to stop Earth’s sun from being consumed. Help arrives from an unexpected source: an alien attempting to save its own world. A 2026 film adaptation was described in the source material as a perfect adaptation, although the novel remains worthwhile for its additional moments.
8. Dungeon Crawler Carl by Matt Dinniman (2024)
Matt Dinniman’s self-published series helped popularise LitRPG science fiction before receiving commercial printing in 2024. Carl, a Coast Guard veteran, is forced into an alien reality television show alongside his ex-girlfriend’s prized show cat.
The pair face bizarre challenges, earn levels and try to satisfy a twisted artificial intelligence while building an audience across the galaxy. Their mismatched partnership is the source of much of the comedy. Seth MacFarlane was working on a Peacock adaptation of the series.
Why these books work
Each title approaches science fiction from a different angle: workplace satire, cosy exploration, artificial intelligence, musical spectacle, video-game humour, gothic mystery, hard science and LitRPG competition. Together, they show that thoughtful speculative fiction can also be fast, funny and highly accessible.
If these stories inspire a sci-fi gaming corner at home, a compact bartop arcade can suit smaller spaces, while a virtual pinball machine adds a more cinematic centrepiece. RETROCADE’s arcade machine buying guide can help compare the options.
