New Sci Fi Romance Releases: 2026 Guide

This is a running guide to the new science fiction romance releases 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.

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, and the launching soon pick at the end of this page states its heat level outright.

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: this is a revised 2026 reissue of an earlier title, opening a year of new Phoenix Adventures installments. Details on the author's site.

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 the publisher's page.

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 the publisher's page.

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 the publisher's page.

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 the author's site.

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

August 18, 2026 · Berkley · Cosmic Chaos #2

Exactly what the title promises, per the publisher: a "zany and sexy romance" about a woman stranded on a distant planet and mated to the warlord alien king, then bundled off to couples counseling.

Tropes (per the publisher's page): fated mates, forced proximity, alien abduction comedy.

Heat level: steamy, per the publisher. Details on the publisher's page.

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.

The last updated date at the top of this page reflects the most recent revision. If a 2026 sci fi romance release is missing, it either did not pass verification or has not been announced with enough detail to list.
