The best fun sci-fi books with adventure, proper romance or friendship, and suitable for both A and YA readers

Why am I passionate about this?

As a planetary scientist and college professor, I love the adventure of finding something new, the wonder of strange worlds, and the magic of mysterious discoveries that behave logically in a way that I can figure out. Unsurprisingly, that is what I like in my fiction too. I also love a story that explores the nature of the interaction between people, particularly in friendship or romance (all proper of course—I’m an old-fashioned guy). The books on this list are all touchstones in my own journey into science and life, and I hope that you can find in them the delight, wonder, insight, and motivation that I have found.

The Arasmith Certainty Principle

By Russ Colson,

Book cover of The Arasmith Certainty Principle

What is my book about?

Jen Hewitt, a quiet geology graduate student, doesn't actually believe in time travel. Were it possible, rocks from the age of dinosaurs should already be cluttered with artifacts from future time tourists. Nevertheless, she proves with fellow geologist Jonathan Renner that a human skeleton encased in Pleistocene rock came from their own time.

Their work, coupled with fundamental research by physicist Susan Arasmith, reveals an unexpected character to the universe that carries them from the safe world of science into a struggle with powers and possibilities they hadn't imagined. The three friends, along with Kar-Tur, a frightening mystic from the ancient past, learn that discovery is sometimes as much about faith as knowledge, and that friendship and love are often found where least expected.

The books I picked & why

Book cover of A Princess of Mars

Russ Colson Why did I love this book?

John Carter finds himself mysteriously transported to another world where he fights for the new friends he finds there. I’ve picked this book from the beginning of the last century because, as a teenager, it helped form my appreciation for the adventure of discovery and to shape my sense of courage and honor.

Honor in a book this old can sometimes feel strained in modern times when we understand that one’s rightness isn’t determined by being white and male. However, the female protagonist in A Princess of Mars is strong and capable, not merely a damsel to be rescued, and the indigenous people include friends of courage and integrity, not merely enemies to be defeated.

Packed as it is with friendship, romance, and discovery, I found the story magical.

Rediscover the adventure-pulp classic that gave the world its first great interplanetary romance-now featuring an introduction by Junot Diaz

In the spring of 1866, John Carter, a former Confederate captain prospecting for gold in the Arizona hills, slips into a cave and is overcome by mysterious vapors. He awakes to find himself naked, alone, and forty-eight million miles from Earth-a castaway on the dying planet Mars. Taken prisoner by the Tharks, a fierce nomadic tribe of six-limbed, olive-green giants, he wins respect as a cunning and able warrior, who by grace of Mars's weak gravity possesses the agility of a…


Book cover of The Stars Are Ours!

Russ Colson Why did I love this book?

I’ve picked this story from the 1950s because, as a teenager, it stirred my sense of wonder at time and space.

Dard Nordis must get safely to the ship that will carry him, his family, and his friends from the tyranny that has overtaken Earth to freedom among the stars. Halfway into the book, hundreds of years pass with the turn of a page, the tyranny of old Earth is just a distant memory, and Dard is in a new world far from the troubled world that he knew.

The story opened up for me the potential for a profoundly new life.  It stirred my desire to discover the universe through scientific exploration. There is no romance here, but there is family, friends, and an adventure like no other!

Book cover of Divers Down!

Russ Colson Why did I love this book?

High school student Kip Morgan wins an internship at an oceanographic institute in Hawaii where he, with help of new friend Julie Scott, overcomes multiple personal and engineering challenges to solve an archaeological mystery and raise a sunken ship from the sea floor. This story from the 1970s was key in guiding me toward a life of science, and the portrayal of a realistic, mentored research experience gave me a vision for what I might do in my own journey through college and into science.

I loved the exotic location, scuba diving, and seafloor exploration, mystery, adventure, and romance!

Book cover of A Thousand Words for Stranger

Russ Colson Why did I love this book?

This fun story from the 1990s revived my youthful joy in reading at a time when the busy-ness of adulthood had stolen it away. Siri has forgotten who she is and is swept into multiple space adventures as she tries to reconstruct her lost memories and regain the power and place she once held with her people. In the process, she finds friendships (the Drapsk!) and romance (Morgan!), and comes to understand herself better.

In reading this book, I realized that the science fiction stories I like best are ones that deal with relationships, mystery, and discovery and not just complicated technologies and their implications for society. I realized that I could have fun reading again if I had some fun science fiction with adventure, romance, and exploration!

Why should I read it?

1 author picked A Thousand Words for Stranger as one of their favorite books, and they share why you should read it.

What is this book about?

The tenth anniversary edition of Julie Czerneda's debut science fiction novel, the story of a woman on the run, from the law, her own people, and an unknown pursuer. Her memory taken from her by a stasis block, Sira must stay free long enough to regain her identity and the full use of her telepathic powers-for failure may cost not only her own future but that of her entire race.


Book cover of Beauty and the Clockwork Beast

Russ Colson Why did I love this book?

This pick reflects changes to speculative fiction that had taken place by the 2010s, including common publication by smaller publishers and frequent mashups of multiple genres. With robots (okay, so they’re called automatons), werewolves, ghosts, and a steampunk 1800s feel, the story is quite different from others in my list, but it shares the mystery, the fun adventure, and the proper romance.

Lucy Pickett comes to a dark manor house, ala Jane Eyre, and must use all her deductive skills and biological knowledge to solve a mystery and perhaps exonerate the dark and dangerous Lord Miles. In this story, I not only found those elements of mystery, discovery, and relationship that draw me in, but I also found the motivation to begin writing again myself.

What is this book about?

When Lucy Pickett arrives at Blackwell Manor to tend to her ailing cousin, Kate, she finds more than she bargained for. A restless ghost roams the hallways, werewolves have been reported in the area, and vampires lurk across the Scottish border.

Lord Miles himself is clearly hiding a secret. He is brash and inhospitable and does not take kindly to visitors—even one as smart and attractive as Miss Pickett. He is unsettled by the mysterious deaths of his new wife, Clara, and his sister, Marie. Could Miles himself be to blame for the deaths?

Working together, Miles and Lucy attempt…

Bailey and the CEO: A Corporate Love Story

By Amy Q. Barker,

What is this book about?

Bailey
Even from afar, you could feel it: the man's ever-present, effortless charm, looks, and for lack of a better word, swagger.
Everyone—and by everyone, I meant every female at Havelin—had speculated about his personal life. We all knew he had two sons, but what about a wife?
Not that I cared.
I was VP of Quality, a widow, and a mother raising two teenage daughters. Love was the last thing on my mind.

Fox
She was staggeringly beautiful.
And she didn’t know it. Not even in the slightest. Not a clue.
I’d never felt like this before.
Even more…
