What are the best sci-fi romance books tell us? Sometimes, love is found in the most unexpected places.

How do Sci-Fi and Romance work together?

Sci-fi and romance are two genres that often go hand in hand. But how do they work together? And why do they seem to be so popular?

One of the reasons sci-fi and romance work so well is that they both offer escape from reality. For a few hours, readers can lose themselves in a different world, full of adventure and love. In addition, both genres often feature strong characters who are fighting for something they believe in. This makes for an exciting read with lots of tension and drama.

Another reason these genres are so popular together is that they both deal with big questions about the world we live in. Sci-fi asks “what if?” questions about the future, while romance asks “what matters most in life”.

Now let's see some outstanding science fiction romance books:

What Are The Best Sci-Fi Romance Books?


Lilith and the Psychopath, by Johnny Malapert (2022)

This book is not about the classic psychopath with violent behavior. Instead, it is about the intelligent and educated individual who can easily integrate in today’s society, regardless of what they heed to face in it.

The modern psychosapien is no longer an introvert with an obvious disorder, but a happy and authentic individual with a successful career. This is Johnny Picaro – a psychopath, a sociopath, or perhaps both of them. Those who know him are aware of what he is capable of.

The book is filled with suspense and covers a relationship that can easily shift between a perfect scenario and a dramatic outcome. It is the type of story that will make you hold your breath as you turn one page after the other.


Finders, Keepers, by Linnea Sinclair (2005)

The book follows Trilby Elliot, a trader trying to avoid the law with a few changes to the starfreighter. An unexpected visitor comes out of nowhere – literally. He seems to have fallen from the sky, and he claims to be from another planet – Avanar.

He comes up with a confusing story and some names that make no sense. But then, despite coming from a different civilization, he seems quite friendly. Trilby knows that even though she can hide Rhis, she does not want to keep him.

She has learned the hard way that men tend to break hearts, so she is cautious about it and refuses his offer for help. Until one day, when something seems to be hunting both her and Rhis. Now, they need to work together in order to survive.


Grimspace, by Ann Aguirre (2008)

Sirantha Jax can definitely stand out in the crowd. She has a rare gene in her DNA, meaning she has some powers that most people would call supernatural. However, she sees herself as a normal person, but she also knows that she can take advantage of her talent.

She can jump ships through grimspace and becomes one of the most appreciated navigators in the Corp. But then, her life changes to 180 degrees when a crash landing kills every passenger. She ends up in jail, with literally no memory of this crash.

Then, a bunch of rogues decides to help her out and release her. She is out of prison, but she has been taken out with a reason – she now must help the group to overthrow the government and establish a new order.


Barbarian Mine, by Ruby Dixon (2015)

The ice planet is harsh and difficult for most survivors. However, it definitely feels good to be alive. There are no takeaways and good TV shows, but life has never been sweeter. The story is told from a personal point of view.

The teller belongs to a tiny tribe. No one is aware of the surrounding dangers, though. A stranger is lurking from the dark and watching what is going on. Eventually, the teller becomes captive and ends up falling in love with the kidnapper.

One thing leads to another… First, it is resonance. Then, there is love. Then, there are kids. However, the man is an authentic barbarian – the type who would chain a woman to claim her. He is the type who could hit someone with a club over the back of the head. But why does she crave for him then?


Gabriel’s Ghost, by Linnea Sinclair (2005)

This is one of the most appreciated and awarded sci-fi romance books out there and tells the story of Chasidah Bergren, a former captain of interstellar ships. She used to be one of the most respected people in the industry, until one day…

Gabriel Sullivan – a dominating mercenary – is thought to be dead. However, he is back somehow, and he aims to give Chasidah a ticket to freedom. But obviously, the possibility to go free is not really free – she has to pay the price.

She refuses to fade away. She stays conscious and aims to keep her mind intact. The soul is going for her body as a host is called Wanderer. Melanie keeps thinking about Jared, another human being still trying to hide.
