Best-Selling Adventure Science Fiction Novels in 2025
1. Gateway: Expeditionary Force, Book 18 by Craig Alanson
In this eighteenth installment of Craig Alanson's bestselling Expeditionary Force series, the Merry Band of Pirates face their greatest challenge yet when Operation Olympic transforms from certain triumph into catastrophic failure. With their usual technological advantage compromised and without their AI companion Skippy, the crew must innovate new solutions to seemingly insurmountable odds in a desperate bid to continue their fight against interstellar threats.
What keeps readers returning to this long-running series is Alanson's masterful balance of military science fiction action with humor and character development. The absence of Skippy—the ancient, sarcastic AI who typically provides miraculous solutions—forces the human characters to rely entirely on their own ingenuity and courage, creating a compelling narrative about human potential when stripped of technological crutches. As the eighteenth book in a beloved series, Gateway demonstrates the enduring appeal of adventure narratives that combine desperate circumstances, camaraderie under pressure, and the exploration of vast cosmic mysteries.
Buy Now2. Project Hail Mary by Andy Weir
Andy Weir's acclaimed novel follows Ryland Grace, who awakens aboard a spacecraft with no memory of his mission or even his own identity. As his memories gradually return, he discovers he's the sole survivor of humanity's last-chance effort to combat an extinction-level threat to Earth. Millions of miles from home with his crewmates dead, Grace must use his scientific knowledge and resourcefulness to complete an impossible mission that will determine the fate of humanity.
What makes Project Hail Mary particularly captivating is how it combines meticulous scientific problem-solving with profound themes of cooperation and sacrifice. Weir builds on his reputation for scientifically rigorous adventure established in The Martian while expanding his scope to interstellar travel and first contact. The novel's ingenious puzzles and solutions showcase human innovation under pressure, while its exploration of unexpected alliance creates an emotionally resonant adventure that has continued to attract new readers in 2025. With its upcoming film adaptation starring Ryan Gosling and directed by Phil Lord and Christopher Miller, the novel has maintained its position as one of the decade's definitive science fiction adventures.
Buy Now3. Star Wars: The Mask of Fear (Reign of the Empire) by Alexander Freed
Set during the critical first year after Emperor Palpatine's transformation of the Republic into the Galactic Empire, this novel explores the early days of resistance through the intertwined stories of three future Rebel Alliance architects: Senator Mon Mothma, Bail Organa, and military extremist Saw Gerrera. As Imperial control tightens across the galaxy, these diverse characters must navigate personal danger while laying the groundwork for what will eventually become a unified rebellion.
What distinguishes The Mask of Fear within the adventure science fiction genre is its focus on political intrigue and covert resistance rather than open warfare, creating tension through the constant threat of discovery in an increasingly totalitarian galaxy. Freed's narrative explores how different personalities respond to oppression—from Mothma's careful political maneuvering to Gerrera's radical approach—while examining the moral compromises required when fighting against overwhelming tyranny. The novel's exploration of the Star Wars universe during this rarely depicted era offers both longtime fans and newcomers a thoughtful adventure that examines how hope survives in the shadow of seemingly unstoppable fascism.
Buy Now4. Red Rising by Pierce Brown
Pierce Brown's explosive debut novel introduces readers to a color-coded caste system on Mars, where low-born "Reds" like protagonist Darrow toil beneath the surface, believing they're preparing the planet for future colonization. After discovering this existence is a lie—Mars has been habitable for generations while Reds serve as slaves to the ruling "Gold" elite—Darrow undergoes a dangerous physical transformation to infiltrate Gold society and its brutal training Institute, where he must compete in lethal games that determine future leadership.
What makes Red Rising a standout adventure is its combination of visceral action with sophisticated social commentary. Brown creates a riveting coming-of-age story within a richly detailed dystopian setting, where physical challenges in the Institute's deadly competition parallel Darrow's internal struggle to maintain his identity and values while pretending to be his enemy. The novel's exploration of class warfare, colonialism, and the corrupting influence of power resonates with contemporary concerns, while its intense competition sequences create adrenaline-fueled adventure that has kept readers engaged well into 2025. As the first installment in Brown's six-book saga, Red Rising continues to serve as an entry point for new readers discovering this modern science fiction classic.
Buy Now5. The Martian by Andy Weir
In this modern science fiction classic, astronaut Mark Watney is accidentally left behind on Mars when his crew evacuates during a dust storm, believing him dead. With limited supplies, no immediate way to communicate with Earth, and years before any potential rescue mission could reach him, Watney must use his botanical knowledge and engineering skills to survive the unforgiving Martian environment while maintaining his sanity through sardonic humor and unwavering determination.
What continues to make The Martian a bestseller in 2025 is its perfect fusion of scientific accuracy with compelling survival adventure. Weir creates tension not through traditional antagonists but through the constant, mortal challenges of surviving on a planet fundamentally hostile to human life. This edition, featuring Wil Wheaton's narration and including bonus materials from Watney's perspective, offers both returning fans and new readers an enhanced experience of what has become the definitive Mars survival story. The novel's celebration of human ingenuity, problem-solving, and resilience creates an inspirational adventure that balances technical detail with emotional resonance, establishing why it remains a touchstone for realistic science fiction adventure.
Buy Now6. Morning Star: Book III of the Red Rising Trilogy by Pierce Brown
In this explosive conclusion to Pierce Brown's original Red Rising trilogy, protagonist Darrow finally launches his long-awaited revolution against the Gold-dominated Society that enslaved his people and executed his wife. After successfully infiltrating the ruling class and climbing its ranks, Darrow must now unite disparate factions—including former enemies—into a cohesive force capable of overthrowing centuries of entrenched power and privilege.
What makes Morning Star particularly compelling is how it transforms from infiltration adventure to full-scale revolutionary warfare, testing Darrow's leadership as he faces betrayal from former allies and confronts the moral complexities of the violent uprising he's unleashed. Brown crafts epic battle sequences across planets and space while maintaining focus on the personal cost of revolution through Darrow's internal struggle to balance vengeance with justice. The novel's exploration of what happens after successful infiltration—when the spy must become a general and potential ruler—creates a multifaceted adventure that examines how revolutions risk becoming the systems they sought to replace, making it a thought-provoking conclusion that continues to resonate with readers in 2025.
Buy Now7. Light Bringer: Red Rising, Book 6 by Pierce Brown
In this latest installment of Pierce Brown's expanded Red Rising saga, Darrow—now known throughout the solar system as the legendary "Reaper"—must transition from symbol of revolution to practical leader in the aftermath of war. Following the events of Dark Age, Darrow faces the challenge of building rather than destroying, shepherding fractious factions toward a new society while confronting those who would plunge the planets back into darkness and oppression.
What distinguishes Light Bringer within the adventure science fiction genre is its exploration of post-revolutionary challenges—the often more difficult work of creating lasting change after the initial triumph. Brown expands his examination of leadership and legacy as Darrow struggles to embody hope rather than fear, reconciling his bloody past with aspirations for a peaceful future. The novel's adventure elements shift from open warfare to diplomatic missions, covert operations, and strategic challenges that test different facets of heroism. As the latest entry in a series that has evolved from young adult dystopian thriller to complex political science fiction, Light Bringer demonstrates how adventure narratives can mature alongside their protagonists and readers, examining the responsibilities that come after victory.
Buy Now8. Silver Elite by Dani Francis
Francis's dystopian romance adventure introduces readers to Wren Darlington, a woman with extraordinary psychic abilities in a world where such "Modifications" are punishable by death. After years of hiding and aiding the resistance movement, a single mistake lands Wren in enemy hands—specifically, in their elite training program called Silver Block. What begins as capture turns into opportunity when Wren realizes her position could allow her to strike a devastating blow against the oppressive regime from within.
What makes Silver Elite stand out is its combination of infiltration adventure with romantic tension, as Wren navigates the deadly competitions of Silver Block training while developing complex feelings for her commanding officer, Cross Redden—the man who represents everything she's fighting against. Francis creates high-stakes physical challenges that test Wren's abilities while paralleling her internal conflict between mission and emotion. The novel's exploration of identity and loyalty in extreme circumstances drives its adventure elements, creating a protagonist who must constantly perform perfection while surrounded by enemies who would execute her for her true nature. This fresh take on dystopian infiltration has quickly gained popularity in 2025 for its combination of intense action, psychic abilities, and forbidden attraction.
Buy Now9. All Systems Red: The Murderbot Diaries by Martha Wells
In this award-winning novella, readers meet a self-aware security android who has secretly hacked its governor module, allowing it independent thought and action while maintaining the pretense of corporate control. Calling itself "Murderbot" (though never aloud), the reluctant hero would rather watch entertainment feeds than interact with the humans it's assigned to protect during a planetary survey mission. When a neighboring expedition goes mysteriously silent, however, Murderbot must investigate potential threats while concealing its autonomous status.
What makes All Systems Red particularly compelling is Wells's creation of a thoroughly unique protagonist whose adventure emerges from unexpected personality rather than traditional heroic motivation. Murderbot's sardonic voice—simultaneously detached from and protective toward humans—creates a refreshing perspective on standard science fiction scenarios. Through its awkward attempts to understand both human social dynamics and its own emerging personhood, Wells explores profound questions about consciousness and identity within an accessible adventure framework. The novella's perfect balance of action, humor, and philosophical depth explains its enduring popularity and ongoing expansion into a television series, with its examination of artificial intelligence feeling increasingly relevant in 2025.
Buy Now10. Artificial Condition: The Murderbot Diaries by Martha Wells
In this second installment of The Murderbot Diaries, the rogue security unit continues its journey of self-discovery by investigating a significant gap in its memory—specifically, an incident where it may have killed numerous humans. Partnering with a research transport ship with its own unique artificial intelligence (nicknamed ART), Murderbot returns to the mining facility where the massacre occurred, seeking truth about its past while reluctantly helping a group of humans who don't realize its true nature.
What distinguishes Artificial Condition is how it evolves the adventure from the first novella, transforming from protection mission to detective story as Murderbot investigates its own history. Wells expands on the series' exploration of artificial consciousness through the relationship between Murderbot and ART—two very different machine intelligences whose interactions create both humor and deeper philosophical questions. The novella's mining facility setting creates claustrophobic tension while its corporate intrigue plot showcases how Wells balances character-driven storytelling with action sequences and science fiction concepts. As Murderbot gradually develops beyond its programming and self-perception, the adventure becomes as much internal as external, continuing to build the series' reputation for thoughtful exploration of autonomy within accessible, entertaining science fiction adventure.
