New Sci Fi Romance Books: The 2026 Releases

This is a running guide to the new sci fi romance books of 2026, verified against publisher, author, and retail announcement pages.

Every date and heat label below is verified against publisher, author, or retail announcement pages, with the source noted per entry.

Where no heat level is stated, this list says "not stated" instead of guessing.

Reviewed August 17, 2026. No titles were added this month.

Three candidates were found, but none could be verified, because the tools needed to read publisher and author pages were unavailable that day.

The update log at the foot records every revision, including the ones that add nothing.

What the 2026 Shelf Looks Like

The shelf is busy this year: big publisher romance lines, a literary space retelling, and new installments from the genre's most prolific indie authors.

Closed door readers should read the heat notes carefully, because most of this list runs warm or does not say.

If closed door is your filter, the complete guide to closed door sci fi romance covers how to vet any of these before buying.

The pick at the end of this page (Launching soon) states its heat level outright.

You can also filter these releases, alongside the rest of our list, by trope, heat, and aliens in the Next Read Picker.

The Starfall Accord is this site's own book: closed door, human characters only, no aliens, enemies to lovers slow burn, with a guaranteed happily ever after.

The 2026 Releases, in Release Order

Full detail, sources, and tropes for each title are in the entries below.

The Starfall Accord is the book this site publishes; read its entry as the author's own account and verify it against the free sample.

At Star's End by Anna Hackett

February 25, 2026 · indie (self published) · Phoenix Adventures #1

A space archeologist and a notorious treasure hunter team up to find the galaxy's most famous treasure.

The author pitches the series as action adventure romance with an Indiana Jones in space energy, and an opposites attract pairing: she follows the rules, he loves breaking them.

Tropes (per the author's copy): opposites attract, treasure hunt adventure, space archeology.

Heat level: no formal label; the author's blurb promises the hunt "ignites a scorching desire," so do not expect a closed door.

Worth Knowing

Worth knowing: this is a revised 2026 reissue of an earlier title, opening a year of new Phoenix Adventures installments.

That reissue cadence has continued through 2026.

The author announced On a Rogue Planet (Phoenix Adventures #3) as out in April 2026, and her coming soon page lists five further Phoenix Adventures installments as TBA 2026.

Exact dates for those are not yet posted, so they are noted here rather than given table entries.

Details on Anna Hackett's coming soon page.

Hell's Heart by Alexis Hall

March 10, 2026 (date per retail and event listings) · Tor Books

A sapphic retelling of Moby Dick set around Jupiter, pitched in its announcement copy as Gideon the Ninth meets Moby Dick.

Space monster hunting, obsession, and a queer romance at the center of a literary science fiction novel.

Tropes (per announcement copy): sapphic romance, space monster hunting, literary retelling.

Heat level: reviews quoted on the publisher's own page describe the romance as explicit and on the page.

One honest note for genre readers: Tor categorizes this as science fiction with a central romance rather than genre romance, so structure your expectations accordingly.

Details on Tor Books' page for Hell's Heart.

Broken Dove by Dani Francis

May 12, 2026 · Del Rey (Penguin Random House) · Silver Elite #2

The sequel to Silver Elite, billed on the publisher's own page as a New York Times bestseller.

Per that page, double agent Wren Darlington has fled the Prime controlled capital for allied lines, her lover and former commander Cross Redden is working against the Primes from inside their ranks.

The war for the Continent between the two factions is escalating.

The publisher files it under both Romance and Science Fiction.

Tropes (per the publisher's copy): double agents, war torn lovers on separate missions, resistance uprising.

Heat level: not stated by the publisher.

Two Notes for This List's Readers

Two notes for this list's readers.

The conflict is between human factions, with no aliens anywhere in the publisher's description, and this is planet bound dystopian science fiction rather than spaceship space opera, so file it beside the romantasy crossover shelf.

Details on Del Rey's page for Broken Dove.

Moss'd in Space by Rebecca Thorne

June 30, 2026 · Bramble (Tor Publishing Group)

The start of a cozy sci fi romance trilogy pitched for fans of Martha Wells.

A sapphic second chance romance featuring a sentient ship whose organic moss computer has, per the publisher, "a snarky attitude and serious abandonment issues."

Found family warmth with a shipboard heart.

Tropes (per the publisher's page): cozy sci fi, sapphic second chance romance, sentient ship, found family.

Heat level: not stated by the publisher; a review quoted on the publisher's page calls it "sweet without being overly saccharine."

Details on Bramble's page for Moss'd in Space.

All We Have Is Time by Amy Tordoff

July 14, 2026 · Atria Books

A debut about a jaded immortal woman and a time traveler from the year 2202 falling in love across the centuries.

Pitched by the publisher for fans of The Invisible Life of Addie LaRue and The Ministry of Time.

Time travel romance rather than spaceship science fiction, so file it on the adjacent shelf.

Tropes (per the publisher's page): time travel romance, immortal heroine, love across centuries.

Heat level: not stated by the publisher.

Details on Atria Books' page for All We Have Is Time.

Vexing Valmir by Ruby Dixon

July 31, 2026 · indie (self published) · Ice Planet Clones #5

The next installment in the Ice Planet Clones series, a spinoff of the Ice Planet Barbarians alien fated mates universe.

The author's page currently says only that more details are coming soon, so this entry is verified for date and series, with the blurb still pending.

Tropes (series context; this title's blurb is pending): alien romance, fated mates.

Heat level: not yet stated for this title; the parent universe is known for open door alien romance.

Details on Ruby Dixon's upcoming releases page.

I Punched an Alien and Now We're in Couples Therapy by Kimberly Lemming

How This List Is Maintained

Entries are added only after verification against the publisher's or author's own announcement page, supplemented by retail listings where a publisher page omits a date, and the entry notes when that is the case.

Release dates shift; where a date moves, the entry is corrected rather than left stale.

Heat levels are quoted or paraphrased from stated publisher and author copy only.

Where no heat level is stated, the entry says so.

This page is on a monthly review schedule.

A review does not always add a title, because a month with no verifiable announcements is a real outcome and gets recorded as one rather than padded.

Update Log

Every revision, most recent first. A review with nothing to add is still logged, so the gap between two dates never has to be guessed at.

• August 18, 2026. Added a cross link to the new debut and new sci fi romance authors guide, which covers how to evaluate a new author before buying rather than tracking specific release dates.
• August 17, 2026. Monthly review, nothing added. Three candidate late 2026 titles were found by search. None could be verified, because the tools needed to read publisher and author pages failed that day, and a search result summary is not enough to list a title here. This update log and the review schedule were added in the same revision.
• July 19, 2026. Structured book data added so the Next Read Picker rebuilds its shelves from this guide automatically, with a stated heat attribution on every entry.
• July 9, 2026. Page published with seven verified 2026 releases in release order, each checked against a publisher, author, or retail announcement.

What Is Missing, and Where to Browse Next
