As the eerie season settles in, these novels blend horror and fantasy in unmistakable fashion: dolls that haunt the evenings, angels whose presence unsettles the mind, pregnancies edging into body horror, and a retro television dimension that could snare you forever. Yet within their pages also lie the twists of affection that survive across eras, first contact unfolding in corners of the world—and in chapters of our own past—that rarely take center stage, plus a sweeping space opera rooted in arithmetic and language. And a shout-out to two titles from our 2026 SFF preview: Nghi Vo’s historical dark fantasy of demonic tides, The Scarlet Ball, and Becky Chambers’s warm, intimate sci‑fi As You Wake, Break the Shell. Enjoooooy!

Audrey Niffenegger, Life Out of Order (Hanover Square Press, October 6)
Audrey Niffenegger has long teased a follow-up to The Time Traveler’s Wife, this time centering on Alba, the Chrono-Displaced daughter of Clare and Henry, and her two partners—Oliver, a fellow traveler through time, and Zach, existing in a linear timeline. The stakes broaden to include a disconcertingly familiar present shaped by dystopia and a troubling far future, with Alba bearing foreknowledge that influences not only the fate of the world but the outcomes of her relationships. Yet the narrative voice doesn’t stop with Alba; readers will also hear from Clare, Zach, Oliver, Alba’s enigmatic stepsister Isadora, and a handful of other surprise viewpoints.

Samantha Josephs, Carrying (Putnam, October 6)
One of the year’s most unhinged premises comes from this trans body horror debut, as perfect housewife Martha begins to suffer the strain of performing impeccable femininity as a stealth trans woman. Keeping her husband happy yet oblivious—managing his baby fever with staged fake miscarriages—only goes so far when Martha begins suffering an inexplicable illness that culminates in an impossible pregnancy. Part The Substance, part Rosemary’s Baby, part something entirely original, Martha’s journey takes her into entirely new territory with her body she’s so carefully controlled. What’s more, it brings her closer to people who give her what she never thought she’d find: someone who has been through the same thing.

Annalee Newitz, A Wall is Also a Road (Tor Books, October 6)
If I consistently trusted any author to voice a non-human protagonist, it would be Annalee Newitz. In their latest, Gardenpath tracks a genderless slime-mold graduate student crafting a dissertation on multicellular life and its preferred habitats. Their fieldwork conveniently leads them to Pompeii, circa 79 AD. In human disguise, Gardenpath befriends a sex worker named Murtis while attempting to warn her about Vesuvius’s impending eruption, all while gathering enough material to satisfy a corrupt professor. It’s a mind‑expanding premise and a captivating vision of intelligent life beyond Earth, especially when set against the backdrop of an ancient history we often imagine as fixed.

Claire North, As We Fall Through Time (Orbit Books, October 13)
If you were a time traveler, would you let a pesky little thing like the canonical timeline stop you from being with your soulmate? Not so for Cal, who meets soldier Olivier during the Napoleonic Wars and creates a paradox to keep him from dying on the battlefield… only for Olivier to disappear from the timeline entirely. And then Cal’s time traveler colleague Fadimatu encounters her own mummified corpse in a museum in 2018—another paradox. Now they must work together to figure out how and where (or rather, when) the timeline is unraveling.

Alex T. Singer, Angel Country (Saga Press, October 20)
In an alternate-history scenario from 1904, America remains fractured into thirteen colonies as maddening angels twist people’s minds and bodies. Scientist Ada Franklin pursues a prototype for human–angel communication—only to wake in her own grave, inexplicably killed and resurrected. Her former research partner has absconded with her life’s work, presumably to fuel human expansion under Manifest Destiny. Acting as both Frankenstein and monster, Ada must rebuild her relationship with her former lover, who has also been altered by their experiments, and pursue her rival across the country before he can establish contact with the angels.

Jane Schoenbrun, Public Access Afterworld (Hogarth Books, October 27)
I’d like to think that Jane Schoenbrun and I frequented the same Buffy the Vampire Slayer fanfiction communities in the early 2000s, even if we discovered Slenderman and other Internet urban legends at different times. With the completion of their “screen trilogy” with Teenage Sex and Death at Camp Miasma, they are exploring many of the same horror themes in a new medium: print! Bleakly sifting through the Internet’s darkest clips, trans content moderator Bethany Peters is shocked to discover a reference to Public Access Afterworld—a pirate TV network whose surreal broadcasts she vaguely remembers from her adolescence watching with her best friend. But is Bethany prepared to step into this other dimension, and for what its monstrous inhabitants will reveal about her past?

Yoon Ha Lee, Code and Codex (Saga Press, October 27)
Yoon Ha Lee’s tremendous new space opera is literally built upon words—that is, the reality-altering lingua rubra, wielded by the powerful Censorate. This singular language in different mouths can control people: the Peacock Aurelia uses the Panopticon Gaze to surveil her empire through citizens’ eyes, while the Basilisk, prisoner of the Urtext Fortress, can kill with the Gaze of Guillotines. When Valentina, Aurelia’s companion and chief Censor, happens upon a book of forbidden-language poetry, her temptation threatens Aurelia’s reign over the Censorate.

Daryl Gregory, The Porcelain Sisters (Tachyon Publications, October 27)
If I had a nickel for every fall 2026 release that centers female rage and power within a haunted doll, I’d own two nickels, which isn’t much, but it’s curious that the pattern has appeared twice. Barbara Truelove’s She’s a Doll is very much in conversation with Daryl Gregory’s latest, where two sisters (one human, one porcelain and possessed) face off against a clan of French sorceresses. When a routine sisterly quarrel leaves the doll Isabel damaged, Ruth, human, takes her on a road trip to track down La Fabricante (The Dollmaker). Yet the sisters end up facing assassins, demons with human familiars, and revelations about their late mother’s standing within Le Clan des Sorcières.

Wole Talabi, The Fist of Memory (DAW, October 27)
In this debut technothriller of first contact, a mysterious spacecraft bearing an alien hive mind called the Irunmole hangs over Nigeria. As the extraterrestrials prepare to arrive, a network of strangers on the ground discover their destinies are linked. Itumeleng, a South African astronomer who has set aside his family’s faith and traditions, relies on visions that help him spot the Irunmole from the start. At the same time, the conflicted assassin Tope takes another job for witchdoctor Baba, only for events to derail and push her into flight—straight into Itumeleng’s path, a man who also recognizes her from his visions. Add a third assassin, obsessed with the singular memory named in the title, and you’ve got a brisk, high-stakes reimagining of first contact.
