Best Science Fiction Romance Books

Evolution of Science Fiction

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.

Romance at Its Finest

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.

Amazing Combination

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.

Main Character

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.

Jeff Martini

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.

Cordelia Naismith

The main character of this space opera series 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.

Lord Aral Vorkosigan

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.

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.

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.
