Set in the Spanish Golden Age, during a time of high‑stakes political intrigue and glittering wealth, The Familiar follows Luzia, a servant in the household of an impoverished Spanish nobleman who reveals a talent for little miracles.

Romances in space are just out of this world. Love in the dangerous, endless expanse of space isn’t easy. Traveling far distances in ships that you often cannot leave is challenging in the best of conditions. In space, the door is locked and you have to make it work. Interplanetary travel, adventure, and romance are not for the faint of heart. Good thing I have some entertaining books to pick up instead of making the trip yourself.

My favorite romances in space involve a level of mystery, political intrigue, and danger. There is just something about a romantic pairing in trouble that really sells me on their mutual respect, teamwork, and problem-solving skills. When you are in space and in trouble, sometimes love is part of the answer, and I think that’s fun.

I mostly pulled a list of romance novels in space with the exception of Malka Older’s The Mimicking of Known Successes which is notably a space mystery with a romance sub-plot. It’s a great read, but if you are looking for a more romance-forward book, there are other options on this list. So, without further fanfare, let’s hop onto a metaphorical ship and take a journey through the small but mighty collection of romances in space.

Blast off with these Romances in Space

Winter’s Orbit by Everina Maxwell Book Cover

Winter’s Orbit by Everina Maxwell

To avoid an interplanetary war, when the Thean ambassador, Jainan, becomes a widow, he quickly enters an arranged marriage with Prince Kiem. All Jainan knows is this prince is his husband’s cousin, and he doesn’t have much control over their new union. While Kiem and Jainan must navigate their new partnership, they face a series of suspiciously deadly accidents. Their tentative feelings might just develop into something too steady to destroy.

The Red Scholar’s Wake by Aliette de Bodard Book Cover

The Red Scholar’s Wake by Aliette de Bodard

When a scavenging bot and data specialist is captured by a pirate fleet, she unexpectedly enters an arranged marriage with the sentient ship leading the pirates. Xích Si thought she would be tortured by the Red Banner. Instead, their leader, Rice Fish, offers her a marriage proposal she cannot refuse. She would get Xích Si’s technical proficiency to investigate Rice Fish’s wife’s death in exchange for protection. As they work together, their emotionless business proposal morphs into a caring relationship that defies both their expectations. It is truly a sapphic romance in space anyone would love to come aboard for.

Aurora Blazing by Jessie Mihalik Book Cover

Aurora Blazing by Jessie Mihalik

While pretending to mourn her dead husband, the supernaturally technologically adept daughter of House von Hasenberg has created a network to save other young women. So, when her elder brother goes missing, Bianca has the connections and skills to find him. In response, her father sends his head of security to retrieve Bianca. Instead, Ian ends up helping her — after all, she is safest by his side. Book 2 in the Consortium Rebellion series remains my favorite, but I do recommend reading the rest of the series to follow the larger intergalactic political mystery.

Temperance struggles to keep her patched-up spaceship and its crew together after their captain runs off with an intern. The debt is impossible to handle, and she cannot afford the new engine they need to stay competitive. When Arcadio arrives to scout a desert planet together, Temper’s frustration is on a knife’s edge. His position as a wealthy second son from the high society that banished her is bad enough shipside. On a mission that involves volcanos, cults, and galactic fighters, it’s almost unbearable. The fact that Temperance is falling for Arcadio anyway might just be the worst thing to happen yet.

Their growing attraction is the least of their worries in this regency-esque romance set in an adventure-packed space fantasy.
