15 Best Science Fiction Romance Books (2020)

When the first science fiction novels came around, they were always intrigued by how a man would react to an extraterrestrial race. The aliens would almost always be interested in enslaving or destroying the human race and many, many books were written with this premise.

Some of these novels were subversive, while others remained adherent to the paradigm which was set up for them. As time went on, the nature of science fiction writing changed accordingly and broad new vistas were journeyed towards as readers didn’t want to be stumped by the same manner of writing.

Of course, we cannot say that for a novel to be considered sci-fi it has to feature extraterrestrials. Invisibility, cybernetic enhancements, and technological developments are all viable themes in science fiction writing, but we just mentioned aliens as perhaps the most intriguing one. Like with other genres, romance entered into the world of sci-fi writing and here we are.

The science fiction romance subgenre presents quite the thrilling stories to read because most of the books in this genre have protagonists with complex and exciting relationships. It’s science fiction at its finest as the thrilling stories are still there, with all of the action and adventure, but there is one more thing in this genre, the passionate and heartwarming relationship between characters that simply no one wants to miss out on.

What will follow will be our picks and choices for the best science fiction romance books.

Touched by an Alien by Gini Koch

 

Gini Koch is a terrific novelist who resides in Phoenix, Arizona, USA. The writing of Koch has always been top-notch and her 2010 novel Touched by an Alien is no exception. Touched by an Alien is the first in the Katherine “Kitty” Katt series.

The main character of Touched by an Alien is none other than Katherine “Kitty” Katt. Katt is currently employed as a marketing manager, though her duty as being part of a jury has occupied her day. As she was coming out of the courthouse, the only thoughts Katt had were concerned with the work that she had missed and that she would need to finish as soon as possible.

Soon, her concentration was broken by a couple’s argument that seemed like it was only getting worse. You can only imagine what Katt thought when she saw one of them turn into a winged, gigantic beast and went on a rampage.

A normal person might have been drawn towards getting the hell out of dodge, but Katt actually ran straight towards the monster to try and stop the ensuing carnage. As all of this is happening, Katt notices that a man has just come into view on her side.

The man notes that his name is Jeff Martini and he is with the agency. Katt is led towards a limousine where she meets Jeff’s boss and her world was never the same after that. Her love life, like her life in general, took a great turn, for better or worse.

Shards of Honor by Lois McMaster Bujold

 

Exceptional writer Lois McMaster Bujold comes from Columbus, Ohio, U. S. Her novel Shards of Honor is doubtlessly one of the best works that Bujold has written. Shards of Honor is the first of the sixteen-book Vorkosigan series. Let’s now proceed further with our best science fiction romance books review.

The main character of Shards of Honor is none other than Cordelia Naismith. Cordelia works as the Beta Colonial Astronomical Survey’s commander, though when she is attacked on a very important surveying mission, her job might entail more than what she bargained for. They were supposed to be making a map of the planets in the local area, but their assailants stopped that plan dead in its tracks. While a big portion of the group gets away, Cordelia and one more person are captured by one Barrayaran man.

The man is none other than the Lord Aral Vorkosigan. Aral’s nickname is the Buter of Komarr. While the Barrayarans were getting ready to attack, Aral himself was assailed upon, in spite of his position in the team.

He takes Cordelia and her crewmate as they walk towards the base of operations of the Barrayarans. The injured crewmate only slows them down, but Cordelia won’t let him perish just like that. As she and Aral didn’t exactly start off on the right foot, they soon learn to rely on each other and must learn to be in sync with the atrocities that are happening around them. We enjoyed the series so much, that we also covered in our article about the best space opera books. Make sure to check it out!

One way to get synchronized is by getting closer. By getting closer, Aral and Cordelia both seem to be wary of embracing the attraction that they feel, though they can’t just go on denying it. As the situations get more and more perilous, the hearts of Cordelia and Aral are ready to leap out of their chests and become one.

Grim by M. K. Eidem

 

The novel Grim by the talented mind of authoress M. K. Eidem is one of her most inventive and creative works, to date. Published in 2013 as the first of a four-book Tornians series – not counting the tie-in novels –, Grim is a superb tale.

The main character of Grim is titular Grim Vasteri. Grim is more often referred to as King of Luda, Grim. Grim is also the most fearless, most powerful member of the Tornians. His superior, who also happens to be his brother, has tasked him with locating and acquiring something which is required for their civilization to prosper and proliferate.

The Tornians are slowly going extinct as a plague-like infection changed something in the females so that newborn female babies are a great rareness. For the longest time, the Tornians have been surveying the local regions for suitable partners, to no luck.

Grim, himself, bears a scar which makes him unsuitable for becoming a parent as no woman would have him, but his mission is of the utmost importance. Lisa Miller, the mother of two bright little children, was widowed a mere year ago. Her spouse was taken by cancer and a day doesn’t go by that she doesn’t miss him.

While she has been encouraged to get back on the dating scene, she is unwilling because of her love. On the grave of her spouse, Lisa is standing and lamenting the loss when she is taken. She regains consciousness and her world is turned upside down as she is on a course for an alien planet.

As both Lisa and Grim begin spending time together, they try and strike out a deal. The deal they agree upon is scarcely to be followed through as they begin catching feelings for one another.

Claimed by Evangeline Anderson

 

Evangeline Anderson is a woman of many talents. Possibly her greatest is her writing prowess. Without a doubt, one of the most beloved works of Evangeline’s is the 2011 novel Claimed. Claimed is the first of a series named Brides of the Kindred, which has thirty more novels in its composition. Claimed is a wonderful entry into our list of the best science fiction romance books and it is easy to see why.

The protagonist, Olivia Waterhouse, is a graduate from nursing school. Olivia thinks that her life is only going to get better from here on out, but she doesn’t know that things tend to get worse before they get any better.

As it turns out, Olivia has been drafted. The Military and its forces are not the ones that have picked Olivia; what Olivia has been chosen for is to be a Kindred bride. The Kindred are very large beings of an alien race. Their population is overwhelmingly male, which is why they need brides. What better planet than Earth? What better bride than Olivia?

One of the Kindred, Baird, has been through much toil and plight in his life. As his suffering has ceased slowly, he is given the chance to claim Olivia as his bride. However, in order to claim her, Olivia must be willing to copulate with him. If she can resist for some thirty days, she is free to go back.

It’s not a lightweight feat, though. Baird might be an extraterrestrial beast, but he has a way with his hands and his tenderness is out of this world. As she tries to resist further, Olivia might be coming around to Baird. But, what of her life back on Earth?

Born of Night by Sherrilyn Kenyon

 

Sherrilyn Kenyon is a brilliant writer who comes from Columbus, Georgia, USA. Kenyon is known for writing amazing science fiction romance novels, but her 1995 publication of Born of Night is surely one of her greatest. Born of Night is the first in her series named The League: Nemesis Rising.

In the so-called Ichidian Universe, there is but one group that controls all others. The League is their name and their rule is not the object of any game. The League’s assassins and hitmen are known to be exceedingly strong, merciless, and without any fear.

As it happens, though, the powerful foundation of The League is broken by the pervading and continuous influx of corrupted members. One of the League’s most capable assassins, NykyrianQuikiades gave up his position because of the corruption in The League.

Since his leaving of The League, Nykyrian has lived as an escapee as The League has been trying to capture him. He is a bit too smooth for them, though. However, one day Nykyrian finds himself forced to protect a girl named Kiara Zamir in spite of his knowing better.

Kiara’s dad is a politician and his rivals want him to be under their will. Kiara’s life takes a sharp turn once she finds herself a runaway with Nykyrian. She loathes the assassins, knowing that they took her mother’s life.

Nonetheless, Kiara needs to find a way to work with Nykyrian if she intends to stay alive. As both of them find themselves needing to rely on the other, a bond is made and this bond only flourishes as both of them are dragged into more and more danger, but also into more and more passion. The Born of Night novel is one of the easiest picks for our list of the best science fiction romance books, as you can surely see.
