12 Best New Sci Fi and Fantasy Books for Fall 2026
Looking for the best new science fiction fantasy books fall 2026? I read and loved these 12 new fantasy and sci fi books filled with magic and adventure.
Fall 2026 Science Fiction and Fantasy Reading Guide: 12 Books I Loved
Hi Bookish Besties, Science fiction and fantasy are probably the genres where I am most willing to follow an author somewhere completely unexpected. Give me a sentient slime mold studying ancient Pompeii. Give me a generation ship with a murder mystery happening in the middle of space. Give me a ballerina searching for the twin sister reality somehow erased. Give me ancient gods, alchemists, talking animals, haunted houses, impossible magic, and people trying to save the world while barely understanding themselves. I am in, sign me up. But the books I remember are never just the ones with the biggest worlds or the coolest magic systems, because I still need something human underneath all of it. I want grief, family, ambition, belief, love, identity, loyalty, and impossible choices. I want speculative ideas that make me think about our own world differently, instead of simply helping me escape it. That is exactly what stood out to me in these Fall 2026 science fiction and fantasy books. I read and loved all 12 books in this guide, and there is so much range here. We have sweeping epic fantasy, science fiction mysteries, dark academia, folk horror, romantasy, literary speculative fiction, apocalyptic fantasy, and books that genuinely made me wonder how an author came up with the idea in the first place. So if you are looking for the best new science fiction fantasy books Fall 2026 has to offer, these are the ones I would put at the top of your list. This guide is also part of my ultimate Fall Reading Guide 2026: Best New Books, where I am sharing even more of my favorite reads across genres.
Best New Science Fiction and Fantasy Books for Fall 2026
What I love about this group is how little these books have in common on the surface. One takes us into a huge war shaped by West African-inspired worldbuilding. Another gives us a biblical apocalypse colliding with modern technology and social media. Another lets an alien slime mold conduct academic research in Pompeii. And somehow all of those books still belong together. The connecting thread for me is imagination with purpose. The strangest ideas here are usually attached to very recognizable questions about who deserves power, what we owe our families, what people will sacrifice for love, whether faith can survive doubt, and what happens when the systems we trust stop making sense.
Quick Picks If You’re in a Hurry
If you just want a few immediate additions to your Fall 2026 TBR:

Now, let’s get into the 12 science fiction and fantasy books that completely took over my reading brain this fall.
12 Fall 2026 Science Fiction and Fantasy Books I Read and Loved
Season of the Serpent by Suyi Davies Okungbowa
Season of the Serpent is the book I would choose when I want fantasy to feel truly epic without losing sight of the people living inside that enormous story. The continent of Oon is fractured, political factions are fighting for power, dangerous creatures have been unleashed, and war is moving closer from every direction. But what made this finale hit for me is how much attention it still gives to individual characters and the relationships among them. Huge events matter, but so do guilt, loyalty, responsibility, fear, and the question of whether anyone can repair damage that has already spread too far. I loved how the different voices gradually come together as the story builds toward its conclusion. The West African influences remain central to the identity of the world rather than feeling decorative, and the final result is sweeping, painful, and deeply human. If you have been reading the Nameless Republic series, this is the kind of ending that makes the entire journey feel worth it.

The Salt King by Natasha Pulley
The Salt King is one of those books where the premise alone made me need to know what was going on. Father Avelyn Brocken is sent back to the English salt mining town where he grew up after another priest apparently turns into a pillar of salt. At the same time, nuclear inspector Dr. Tallis Osho is investigating strange phenomena around the Dead Sea. Soon, the same eerie salt light begins spreading across the world, damaging electronics and affecting people in increasingly frightening ways. What I loved is that underneath the apocalypse is this constant argument about belief. What counts as a miracle? What happens when science cannot completely explain something? Does believing in something make us more capable of seeing it, or more vulnerable to being manipulated by it? The story gets enormous, but the emotional center stays grounded in two complicated people trying to understand what they believe and whether they should face the impossible alone. This is such a strong pick if you like fantasy that mixes religion, science, mythology, technology, and end-of-the-world stakes.

Blacktail by Scott Hawkins
Blacktail is one of the strangest fantasy books on this list, and I mean that as a compliment. The story is told through a world where animals have finally had enough of humans destroying their habitats, poisoning their environments, and killing without need. Blacktail, a wolf who has already lost almost everything to human violence, is transformed from a grieving predator into something much more dangerous after an ancient feline sorceress sets him on a path of revenge. From there, the book becomes part folk horror, part animal fantasy, and part apocalypse. What made it work for me is how human the animals feel without simply becoming humans in fur. They still operate through hunger, territory, protection, instinct, and their own strange traditions. There is humor here too, which somehow makes the violence even more unsettling. If you want dark fantasy that feels primal, weird, angry, and completely different from the standard hero’s journey, Blacktail is one of the standout reads of the season.

Our Cut of Salt by Deena Helm
Our Cut of Salt is easily one of the most emotionally devastating books in this guide because its supernatural horror grows directly out of family history and political trauma. In the present, Palestinian American Marina wants to understand the history her family rarely discusses and travel to Haifa, where her grandmother Nuhad lived before being displaced. In another timeline, we follow teenage Nuhad as she tries to survive in Haifa while Palestinians are being forced from their homes. When Marina finally reaches her family’s old house, she discovers a place that seems to recognize her. The house itself is haunted, but the deeper horror comes from everything humans have done to one another around it. I loved the way the timelines slowly reveal what this family has carried across generations and how the supernatural elements never distract from the historical violence at the center. This is lyrical, brutal speculative fiction about memory, displacement, inheritance, and the way trauma can live inside both people and places.

Dark Reading Matter by Jasper Forde
Dark Reading Matter is pure chaos in the most delightful way. Thursday Next is back, and this time reality, fiction, authorship, technology, and even the reader seem to be colliding with one another. The story revolves around the Dark Reading Matter, a strange underworld of forgotten and discarded text, but explaining the actual plot almost feels beside the point because this book is having so much fun breaking the rules of what a novel is supposed to do. There are shifting fonts, metafictional interruptions, fictional versions of the author, characters questioning their own reality, terrible jokes, literary references, and even instructions aimed directly at us as readers. Underneath all of that silliness is a surprisingly serious question about what happens to storytelling when art becomes something institutions or technologies want to control. I loved that the book can make jokes about literature while also defending the strange freedom of fiction. If you like books about books, metafiction, absurdist fantasy, and stories that know perfectly well how weird they are, this is your fall pick.

A Wall Is Also a Road by Annalee Newitz
A Wall Is Also a Road gave me one of my favorite science fiction premises of the season. Gardenpath is a sentient slime mold studying intelligent multicellular life on Earth for an academic dissertation. Their research brings them to Pompeii, where they disguise themselves as human and become far more emotionally involved with their research subject than any responsible academic probably should. I loved seeing humanity from a completely outside perspective because normal human behaviors suddenly become bizarre when someone who is not human has to interpret them. But the book also has a genuinely warm center. Gardenpath becomes attached to Murtis, a sex worker in Pompeii, while also navigating an abusive academic advisor and the looming eruption of Mount Vesuvius. There is found family, community, ethics, exploitation, and a lot of very strange science fiction wrapped around an emotionally recognizable story about wanting connection. If you like speculative fiction that makes you laugh and think at the same time, this one is wonderfully odd.

Line of Descent by Adam Oyebanji
Line of Descent combines two things I almost always enjoy separately and makes them even better together: deep space science fiction and a murder mystery. The generation ship Archimedes is more than a century into its journey to a new home when everything starts going wrong. Resources are running low, the ship is deteriorating, and some passengers want to abandon the mission even though they have already completed most of the voyage. Then, security officer Faisal Vasconcelos has to investigate an alleged kidnapping, followed by the discovery of a body inside one of the ship’s reproductive incubators. I loved that the worldbuilding never overwhelms the mystery. The ship feels believable and complicated, but I was still able to focus on clues, suspects, motives, and the question of what exactly happened. The larger crisis makes every investigation more urgent because one murder is happening inside a community that may already be running out of time. If you love fair play mysteries and big science fiction settings, this is such a satisfying combination.

Mothsblood by Lynn D. Jung
Mothsblood is exactly the kind of dark academia fantasy I want to read when fall arrives. Larkspur Lee is an American scholarship student at an elite alchemy school in Paris, where connections, family status, and power matter almost as much as actual talent. She is ambitious enough to know that access to the right mentor could change everything, so when she earns an apprenticeship with the immortal Petronelle Flamel, she sees a path into the highest levels of alchemical society. Then Flamel is murdered. From there, the glamorous world Lark desperately wanted access to begins revealing how ugly its power structures really are. I loved the tension between Lark’s ambition and her growing understanding of what progress and innovation may actually cost. Add her complicated family relationships, traumatic past, mysterious moth visions, and attraction to a dangerous woman tied to the immortals, and there is so much happening beneath the academic setting. Read this if you want alchemy, secret societies, murder, obsession, and a heroine who desperately wants power while beginning to question who gets to define it.

The Inevitable Undoing of Zahara Douglass by Leslye Penelope
The Inevitable Undoing of Zahara Douglass starts with one of the most haunting ideas in the guide: What if someone you loved disappeared and reality rewrote itself so completely that nobody else remembered that person had ever existed? Zahara Douglass remembers watching her twin sister Annica disappear years earlier, even though every trace of Annica seems to have been erased from the world. Now Zahara is a successful ballerina, but returning to her California hometown brings everything she has tried to suppress back to the surface. She begins searching for evidence that her sister was real and finds a mysterious digital trail that may prove she is not imagining anything. I loved the combination of family grief, technology, myth, noir mystery, and Y2K anxiety. Zahara’s identity as a dancer also gives the writing an interesting sense of movement. At its core, though, this is a story about what we are willing to sacrifice for someone we love and whether getting them back is worth changing everything else.

Scion by James Islington
Scion is my recommendation for anyone who wants science fiction that moves. Azure is a biomechanically enhanced assassin taking dangerous contracts with the help of his AI assistant, when a new assignment sends him to protect a wealthy older woman living inside a remote underground bunker. The problem is that the same organization employing Azure may also want her dead, and Azure himself cannot entirely determine what role he is supposed to play. From there, the book piles on mysteries involving Azure’s past, his dead friend, the identity of the woman he is protecting, and the larger forces manipulating both of them. I loved the sheer momentum here. There are bioengineered monsters, assassination attempts, organized crime, cloning, questions about immortality, and just enough ambiguity around Azure’s own origins to keep me wondering what else the story might reveal. If your ideal science fiction book is one you accidentally read for three hours because there was never a good place to stop, Scion absolutely understands the assignment.

Drown the Bones by Alexandra Kennington
Drown the Bones is the romantasy pick for readers who still want plenty of grief, faith, politics, and mystery underneath the romance. Merridan has always expected her twin brother Von, to inherit the throne while she devotes herself to serving the Goddess and helping spirits move into the Afterworld. Then Von is murdered, and suspicion immediately falls on the neighboring kingdom of Nova. Desperate for answers, Merridan uses forbidden magic and accidentally binds herself to the spirit of Phoenix, Nova’s murdered crown prince. Now the two dead princes seem connected, their kingdoms are approaching war, and Merridan has to work with the person she was raised to consider an enemy. I loved that the slow burn romance grows alongside Merridan’s increasingly uncomfortable questions about everything she has been taught. Her faith, family, politics, and understanding of another culture all begin shifting at once. If you want romantasy where the romance matters but is not the only thing carrying the story, this gives you plenty of emotional yearning and bigger ideas to chew on.

Dreamland by Olivie Blake
Dreamland is for readers who want their fantasy darker, more atmospheric, and a little poisoned by ambition. Anya Morris is a struggling actress desperate to escape the life everyone around her expects her to accept. Her opportunity arrives through Teddy Finch, a Hollywood nepo baby who brings her into the orbit of old money, wealth, access, and a deeply unsettling mansion full of people who seem to know more than they are saying. Soon, Anya is being asked to watch a mysterious man named Julian, and the deeper she gets into this world, the more obvious it becomes that the opportunity she wanted may come with an enormous cost. What worked for me most is the atmosphere. The heat, traffic, money, fame, desire, and Hollywood excess all become part of this suffocating feeling that something is very wrong. If you like modern gothic stories about ambition, class, fame, dangerous privilege, and women walking knowingly toward bad decisions, this is a wonderfully moody fall read.

How to Build the Perfect Fall 2026 Science Fiction and Fantasy TBR
If you are building your own Fall Reading Guide 2026 stack, here is how I would personally mix these books together:
- Choose one sweeping epic fantasy: Season of the Serpent
- Add one apocalyptic fantasy with huge philosophical questions: The Salt King
- Pick one dark and unusual horror fantasy: Blacktail or Our Cut of Salt
- Include one big science fiction mystery: Line of Descent
- Add one strange literary speculative novel: A Wall Is Also a Road or Dark Reading Matter
- Choose one fast-paced science fiction adventure: Scion
- Add one magical academic setting: Mothsblood
- Pick one emotionally driven speculative family story: The Inevitable Undoing of Zahara Douglass
- Then round everything out with romance and fantasy: Drown the Bones
That gives you a fall stack with a little bit of everything. You have enormous fantasy worlds, intimate family grief, bizarre aliens, deep space murder, alchemy, romance, folk horror, haunted history, and one extremely angry wolf. Which sounds like a very successful reading season to me.
Which Fall 2026 Science Fiction or Fantasy Book Should You Read First?
- If you want epic fantasy, start with Season of the Serpent.
- If you want something huge, strange, and apocalyptic, go with The Salt King.
- If you want your fantasy dark and unsettling, choose Blacktail.
- If you want horror rooted in family history and generational trauma, read Our Cut of Salt.
- If you want science fiction plus a mystery you can actually try to solve, pick Line of Descent.
- If you like your speculative fiction weird and funny, A Wall Is Also a Road would be my recommendation.
- If you love books about books and metafiction, go directly to Dark Reading Matter.
- If dark academia is your fall weakness, Mothsblood is waiting.
- If you want romance, grief, magic, and enemies forced to work together, pick Drown the Bones.
Final Thoughts
This Fall 2026 science fiction and fantasy list reminded me why I love speculative fiction so much. These books can give us completely impossible worlds and still ask questions that feel incredibly familiar. What would you sacrifice for your family? What happens when belief becomes dangerous? Who gets access to power? Can you repair something after you helped break it? What does progress cost? What makes a community worth saving? And, apparently, what would happen if a sentient slime mold had to survive graduate school? All important questions. What makes this group especially fun is that there really is something here for every version of my speculative reading mood. I can go epic, romantic, horrifying, philosophical, weird, action packed, or completely genre bending without leaving the category. Have you read any of these books yet, or are you adding any of them to your TBR? Tell me which science fiction or fantasy book immediately caught your attention because I would love to know which world you are disappearing into first this fall.
