Book cover of The Voyage of the Space Beagle

John Triptych Author Of Visitor

From my list on cult sci-fi and fantasy you may not have heard of before.

Why am I passionate about this?

The reasons I’ve chosen these particular books is because of my penchant for reading offbeat stuff, and unearthing little-known works that I feel deserves more attention. My tastes are eclectic, and I’ve done a lot of research when it comes to finding the true origins of pop culture. Having written and published more than forty books that range from science fiction to crime thrillers, I’ve wanted to share my findings in the hopes that others will notice something new and exciting as well.

John Triptych Why did John love this book?

If you want to know the origins of Star Trek and the Alien movies, look no further. It’s essentially a mash-up of short stories with an encompassing theme. Set centuries in the future, the diverse human crew of the Space Beagle encounters hostile aliens as they explore the universe.

Each sub-story sometimes presents it from the alien’s perspective, and what a unique set of monsters they are! These various creatures run loose onboard the ship, and they possess incredible powers that could wipe everyone out. The protagonist uses a new generalist philosophy called Nexialism to defeat each one in turn. Sounds familiar? Of course it does, because this is the book that started it.

What is this book about?

One of the great original classics of modern SF returns!

An all-time classic space saga, The Voyage of the Space Beagle is one of the pinnacles of Golden Age SF, an influence on generations of stories. An episodic novel filled with surprises and provocative ideas, this is the story of a great exploration ship sent out into the unknown reaches of space on a long mission of discovery. They encounter several terrifying alien species, including the Ix, who lay their eggs in human bodies, which then devour the humans from within when they hatch. This is one of the most…


Book cover of We're Off to Look for Aliens

Gillian Rogerson Author Of You Can't Eat a Princess!

From my list on children's picture books to read aloud.

Why am I passionate about this?

Since an early age, I loved getting lost in a good story and knew I wanted to be a writer one day. As an adult, I tried writing in many genres but it was when I had my children that I knew I wanted to write children’s bedtime stories. I loved that special time at the end of a busy day when I could snuggle down with my children and get lost in a story with them. I now write children's bedtime stories for a podcast called Koko Sleep. The stories are written in a soothing way and are designed to help the listeners drift easily to sleep.

Gillian's book list on children's picture books to read aloud

Gillian Rogerson Why did Gillian love this book?

I worked as a classroom assistant for ten years and read a lot of books to the younger children, and this one was always a favourite for them. The children loved the funny rhymes and there would be lots of giggles because they knew what was going to happen next. The illustrations are amazing and they inspired the children to draw their own aliens. This book was read so many times that the pages started to fall out, but they were lovingly put back by the children.

Book cover of Up the Line

Seth Chambers Author Of Little Bird

From my list on time travel and the paradoxes that arise.

Why am I passionate about this?

I've been an avid reader of SF in general, and its sub-genre of time-travel, for most of my life, and have tackled this topic in my own writings as well. Time-travel tales often deal with inherent paradoxes, such as the Grandfather Paradox, which asks: If you go back in time and kill your grandfather, would you then never be born and therefore never commit the murder? If so, then your grandfather lives and you were born and . . . Such paradoxes boggle the mind and provide fascinating territory for SF authors to explore. 

Seth's book list on time travel and the paradoxes that arise

Seth Chambers Why did Seth love this book?

This is a novel that explores all the complexities and paradoxes and oddities associated with time travel. It takes place in a future world in which time travel is a part of life, and so must be monitored and regulated like any other technology. Because time travel holds such a huge potential for disaster, strict rules must be established and enforced. But what happens when somebody flaunts those rules for their own personal enjoyment? This novel explores these concepts in a wild, and often erotic, fashion. 

This book really perpetuated my love of time-travel tales and all the complexities involved in a society where time travel is an accepted norm. It's a totally fun novel that deals with some truly existential concepts in an entertaining way and inspires that sense of wonder that fans of SF crave. It's one of those stories that stick with you for many, many years…

1 author picked Up the Line as one of their favorite books, and they share why you should read it.

What is this book about?

Time travel spelled problems for the couriers of the Time Service. Shuttling backwards and forwards over the centuries they had to be wary of creating paradoxes - like meeting themselves watching the sack of Rome, or sleeping with their own ancestors.

Of course, it also gave them the chance to amass wealth by the discreet use of their prior knowledge. The penalties were fierce and the Time Police implacable in their pursuit of lawbreakers. But it was still worth taking the risk.

Jud Elliot took it when he met the marvellous transemporal paradox called the Pulcheria. He couldn't resist her…


Book cover of A Tale of Stars and Shadow

Sally Altass Author Of The Witch Laws: Book One of The Moon Magic Chronicles

From my list on fantasy sweeping you into a beautiful, scary world.

Why am I passionate about this?

When I read, I’m not just seeing the words on a page; I’m escaping into the world crafted by the author. Since I was a child, I’ve always been a lover of fantasy – it was an escape for me to slip between the pages and be a part of the world inside them. Especially if they were beautiful and filled with hidden danger. I wanted to have my heart pound out of my chest, to have the thrill of magic, wonder, and fear. Now, I try to write those types of worlds; because of the books which inspired me. I only hope you love them as much as I do. 

Sally's book list on fantasy sweeping you into a beautiful, scary world

Sally Altass Why did Sally love this book?

A Tale of Stars and Shadow exceeded my expectations; mainly because it was one of the first fantasy stories that I’d read which wasn’t exclusively aimed at young adults. 

This is a book for grown-ups, dealing with adult themes (although not sex, perse) and political intrigue. It follows Tallyn, a grief-torn warrior who accepts a posting to protect the spoiled prince of the Winged folk in an exotic country; with beautiful and deadly scenery. I wanted to be in Mithranar – to swim in the clear waters of Feather Bay.

1 author picked A Tale of Stars and Shadow as one of their favorite books, and they share why you should read it.

What is this book about?

A broken warrior. A notorious thief. A mission that could change the world.


Talyn Dynan was the finest fighter of her generation. But after a combat mission goes tragically wrong, she is left broken and wracked with guilt. When Talyn is sent on a twofold mission to Mithranar—protect a winged folk prince while secretly hunting a criminal who is a key to a much greater mystery—she’s immersed in a tangle of ruthless political games. There’s far more at stake than she realised, and a single mistake could mean her death.

Book cover of That Hideous Strength

Timothy B. Barner Author Of Eyes of God

From my list on mind-expanding, original literature.

Why am I passionate about this?

I grow bored reading the same thing over and over, so I don’t. My favorite books challenge me, teach me, blow the walls out, and expand my horizons. I want books to take me to unexpected places and show me worlds existing and otherwise that I never dreamed could be out there. I’ve never been a fan of genre literature that strictly “follows the rules” for that reason. Some of the books on this list are from genres, but they still differ from the predictable. I want to be surprised, and then you’ll hold my attention for the entire novel, and I’ll refer back to it for years.

Timothy's book list on mind-expanding, original literature

Timothy B. Barner Why did Timothy love this book?

At times, C.S. Lewis eschewed writing what would be expected of him. For example, every volume of his Chronicles of Narnia takes the reader in a new direction, a new aspect of that fantasy world, instead of merely rehashing the popular story of the first novel, as many series do.

Science Fiction was not his field, yet Dr. Lewis dived into the genre for three novels and proved he was a master. The third book in Dr. Lewis’s space trilogy continues the epic interplanetary story of the first two but brings the tale to a dystopian Earth.

At first, the story seems unrelated to the earlier space-traveling books of the trilogy, as an engrossing study of professors playing politics and strange dreams. As the novel progresses, however, this proves to be a much larger story involving aliens, demons, the very fabric of human existence, and the return of Merlin. 

By C. S. Lewis,

Why should I read it?

5 authors picked That Hideous Strength as one of their favorite books, and they share why you should read it.

What is this book about?

Just as readers have been transfixed by the stories, characters, and deeper meanings of Lewis's timeless tales in The Chronicles of Narnia, most find this same allure in his classic Space Trilogy. In these fantasy stories for adults, we encounter, once again, magical creatures, a world of wonders, epic battles, and revelations of transcendent truths.

That Hideous Strength is the third novel in Lewis's science fiction trilogy. Set on Earth, it tells of a terrifying conspiracy against humanity. The story surrounds Mark and Jane Studdock, a newly married couple. Mark is a sociologist who is enticed to join an organization…


Book cover of Embassytown

Gillian Cross Author Of After Tomorrow

From my list on about communication.

Why am I passionate about this?

I’ve been writing children’s books all my adult life. That means trying to find ways to communicate exactly what I’m imagining. I love words and stories. As a teenager, I wrote down my favourite words and carried them around with me. When I had children, I was fascinated by how fast they learned to make themselves understood, with and without words. The words we choose are important – but they’re only one way to communicate. What about pictures? Body language? Online media? Pheromones? The signals animals and plants give out? The more I learn about communication, the more fascinating it becomes.

Gillian's book list on about communication

Gillian Cross Why did Gillian love this book?

I like science fiction when it’s about big ideas and they don’t come much bigger than this. Imagine a world where the alien inhabitants are incapable of lying. They can’t even use figures of speech, like similes, unless someone has acted out what they want to use as a comparison. (Avice, the girl who ate what was given to her, is the human simile who narrates the story.) Sounds idyllic? Maybe – until you start thinking about how you’d make plans, or discuss ideas. This isn’t an easy read, but it’s fascinating and it made me think hard.

1 author picked Embassytown as one of their favorite books, and they share why you should read it.

What is this book about?

Winner of the Locus Award for Best Science Fiction Novel, China Mieville's astonishing Embassytown is an intelligent and immersive exploration of language in an alien world.

Embassytown: a city of contradictions on the outskirts of the universe.

Avice is an immerser, a traveller on the immer, the sea of space and time below the everyday, now returned to her birth planet. Here on Arieka, humans are not the only intelligent life, and Avice has a rare bond with the natives, the enigmatic Hosts - who cannot lie.

Only a tiny cadre of unique human Ambassadors can speak Language, and connect…


Book cover of Although the Day is Not Mine to Give, I'll Show You the Morning Sun

Elizabeth B. Splaine Author Of Devil's Grace

From my list on medical thriller/mystery with a spiritual twist.

Why am I passionate about this?

Before becoming an opera singer, I received my Masters in Healthcare Administration and worked in various healthcare settings, from a community health center to a large teaching hospital. I learned first-hand how the best-intentioned clinicians can make mistakes, and how those mistakes can lead to unintended consequences that can harm patients. Although it’s terrifying to think about, the best defense is to self-advocate as much as possible. It’s your body and your decision. Don’t give away your power.

Elizabeth's book list on medical thriller/mystery with a spiritual twist

Elizabeth B. Splaine Why did Elizabeth love this book?

This book sat on my parent's bookshelf when I was a child, and I would sporadically remove it and read it at various stages of my life. As an adult, I returned to it when I had three kids of my own. It reminds me how important family is and how fleeting childhood is. Angela learns this the hard way in my own book, and I pictured her reading this book after her children had been stolen from her. As I was writing, it always left me in tears.

Book cover of Star Trek: First Contact: The Making of the Classic Film

Troy Lambert Author Of The Tao of Trek

From my list on Star Trek for Trekkies and science nerds.

Why am I passionate about this?

I’ve been fascinated by Star Trek since I was a young child and went to my first convention, seeing a gorgeous Uhura walk by trailed by three gentlemen dressed as Mr. Spock. One of my local librarians must have been a Trekkie because I checked out stacks of novels from the likes of James Blish and Vonda McIntyre. Now, as an author myself, I feel privileged to have not only been a Trekkie for many years but to have written a book about Star Trek with one of my best friends. I hope you enjoy these Star Trek books, and the many others that are coming this year and beyond, as much as I have. 

Troy's book list on Star Trek for Trekkies and science nerds

Troy Lambert Why did Troy love this book?

Star Trek: First Contact for me symbolized a return to the big screen for Star Trek, and the introduction of the Borg, one of the constant “villains” in the series from that point forward. But one of the things that has always fascinated me has been how these movies themselves spawned innovation in filmmaking. 

This is certainly no exception, and Joe Fordham expertly explores how this film did just that in a coffee table book filled with never before seen production art, cast interviews, and more.

What is this book about?

An in-depth look at the making of Star Trek: First Contact, featuring rare and previously unseen production art and new and exclusive cast and crew interviews.

Twenty-five years ago, Star Trek: First Contact saw Picard, Data, and the Enterprise crew go back in time to stop the Borg before they could prevent Earth's first contact with an alien species and assimilate the entire planet.

Celebrate this landmark anniversary by taking a deep dive into the stories behind this beloved film. This beautiful coffee-table book is full to the brim of archival material, behind-the-scenes photography, concept art, production designs, and much…


Book cover of Gust Front

B.K. Bass Author Of What Once Was Home

From my list on ordinary people surviving the extraordinary.

Why am I passionate about this?

I lived in small towns with “ordinary” people most of my life, so books where people from small towns contend with situations beyond the ordinary fascinate me. I also served in the US Army as a nuclear, biological, and chemical operations specialist and am a military history buff, so anything with a military spin is all that more engaging for me and I developed a morbid fascination for just how easy it would be for us to end civilization as we know it. Therefore, military science fiction and post-apocalyptic fiction are among my favorite genres. 

B.K.'s book list on ordinary people surviving the extraordinary

B.K. Bass Why did B.K. love this book?

Parts of Gust Front hit home. I read this while living in the Appalachians, so seeing Cally preparing for an invasion in a remote valley in Georgia, and the subsequent fighting that takes place in and around the Appalachians, struck a nerve with me. If the worst happened, up to and including the alien invasion depicted here, would the mountains be the best place to hold out and resist? The scope of the novel covers many settings, including other familiar ones like Washington D.C., all of which ground the speculative premise of an alien invasion in a story that feels very real; something that any of us could be forced to live through.

Book cover of Astrobiology: The Search for Life Elsewhere in the Universe

Mike X Cohen Author Of Linear Algebra: Theory, Intuition, Code

From my list on for people who can’t read five books on the same topic.

Why am I passionate about this?

I am an associate professor of neuroscience at the Donders Institute in the Netherlands. My research lab focuses on discovering how the brain uses electrical signaling to compute information, and transfer information across different regions of the brain. I also have a few decades of experience teaching scientific coding, data analysis, statistics, and related topics, and have authored several online courses and textbooks. I have a suspiciously dry sense of humor and insufficient patience to read five books on the same topic.

Mike X Cohen Why did Mike love this book?

“Are we alone?” An age-old question that we may never answer. Andrew May walks us through the scientific study of whether there might be life elsewhere in the universe, and how we might identify it. And by “scientific study,” I mean actual scientific investigations, not wishy-washy sci-fi fluff. The book is both inspiring and terrifying, because the immense distances in space and time make you realize that intelligent life is both incredibly insignificant and incredibly precious.

Extraterrestrial life is a common theme in
