Book cover of The Face of the Unknown

Scott Pearson Author Of The More Things Change

From my list on Star Trek novels that are sequels to the series.

Why am I passionate about this?

I’m a lifelong raving Star Trek fan; I literally can’t remember a time I didn’t love Trek, which I was watching in syndication by the time I was in the second or third grade over fifty years ago. I started reading Trek novels in the seventies when the books and the underrated animated series were the only new Trek to be had. My dedication to the franchise eventually turned professional, first by writing some stories and novellas published by Simon & Schuster and then by becoming the freelance copyeditor of the novels. (In fact, I copyedited the last novel on this list.) Choosing just five was painfully difficult!

Scott's book list on Star Trek novels that are sequels to the series

Scott Pearson Why did Scott love this book?

I always wanted to know what happened after the episode "The Corbomite Maneuver," which ended with a young crew member sent off to the mysterious First Federation—never to be heard from again in the shows. I always enjoy Christopher L. Bennett’s meticulous sci-fi world-building, and in his hands, the First Federation is revealed to be a suitably fascinating, if isolated, society.

I loved the sense of vastness achieved by getting beyond the United Federation of Planets. I also enjoy when a story takes full advantage of the continuity of the franchise, and The Face of the Unknown smoothly sets up elements of the often overlooked Animated Series of the 1970s as well as Star Trek: The Motion Picture.

What is this book about?

Investigating a series of violent raids by a mysterious predatory species, Captain James T. Kirk discovers that these events share a startling connection with the First Federation, a friendly but secretive civilization contacted early in the USS Enterprise's five-year mission. Traveling to the First Federation in search of answers, the Enterprise suddenly comes under attack from these strange marauders. Seeking refuge, the starship finds its way to the true home of the First Federation, an astonishing collection of worlds hidden from the galaxy beyond. The inhabitants of this isolated realm are wary of outsiders, and some accuse Kirk and his…


Book cover of The Robert Sheckley Collection

Richard Sparks Author Of New Rock, New Role

From my list on fantasy that aren’t afraid to be funny.

Why am I passionate about this?

I’ve now completed four books in my New Rock fantasy series; and, while the stories are full-on adventures in a strange (but strangely familiar) new world, they contain lots of comedic characters and situations. I come from a background of comedy writing. Comedy isn’t nice people telling jokes. That’s a dinner party. Comedy is all about pain, fear, misery, confusion, suffering, mistakes, betrayals, accidents, dangers, and things going horribly wrong—and what good adventure doesn't have those? And why wouldn’t any strange new world be full of them? New Rock New Role, the first book in the series, is published on December 12th 2023 by CAEZIK SF & Fantasy.

Richard's book list on fantasy that aren’t afraid to be funny

Richard Sparks Why did Richard love this book?

Robert Sheckley stands out from his contemporaries of the golden age of science fiction by being not just great but also often very funny. 

Sheckley has a wry, insightful wit, which puts him in a class of his own among the giants of the post-WW2 era. Start with his eight stories of the AAA Ace Interplanetary Decontamination Service. Great idea, great characters, great settings (two shysters running a fly-by-night planetary fixer-upper service, on the cheap): they are light, effortless, unpretentious, insightful, and brilliant. 

It’s basically Ghostbusters in space. What more could you want?

First published in the science fiction magazines of the 1950s, his numerous quick-witted stories and novels were famously unpredictable, absurdist, and broadly comical.

Book cover of In the Ocean of Night

Allen Steele Author Of Coyote

From my list on lost classics of space science fiction.

Why am I passionate about this?

Okay, so you’ve read Dune, you’ve read Starship Troopers, you’ve read 2001: A Space Odyssey, and maybe you’ve even read From Earth to the Moon and The First Men in the Moon. Seen the movies, too (or maybe you cheat and say you’ve read the books when you’ve only seen the flicks). Bet you think that makes you an expert on science fiction about space, right? Not even close! If you want to read more than just the well-known classics everyone else has, find these books. Some have become obscure and are now out of print, but they’re not hard to find; try ABE, eBay, and local second-hand bookstores. They’re worth searching for, and then you’ll really have something to talk about.

Allen's book list on lost classics of space science fiction

Allen Steele Why did Allen love this book?

This novel, about the discovery of an alien probe hidden within an Earth orbit-crossing asteroid and the search for extraterrestrial intelligence it provokes, is the first volume of a long, six-volume epic, the Galactic Center series, that is regarded by most critics as a landmark work. You can read this novel on its own or you can go from there with the rest of the series; in any case, it’s hard SF at its thought-provoking best.

New book alert!

Why am I passionate about this?

As a child, I lived in a small valley sheltered from the night city lights. I could see the stars, and from that time, that is where my imagination dwelled. As a teenager, I read several of the books I have listed here, and from that point, I was inspired to read more and also to write myself. I sincerely believe that despite our current problems, humanity will outlive its troubled childhood and reach for the stars. We are destined for the stars, and only in the works of science fiction writers is that future explored. The books below helped me to become a successful author in my own right.

Book cover of SkyWake Invasion

Janelle McCurdy Author Of The Lightcasters

From my list on for gamers.

Why am I passionate about this?

I've always been a gamer, even now that passion burns bright. My favourite genres being FPS, Horror, Fighting, and adventure games. There's nothing like delving into a new game and feeling the adrenaline that comes with slaying beasts and leveling up, or getting emotional during a cinematic movie-like horror game. I've been gaming since I was a child all the way up until today. Gaming has always had my heart, which has led to me writing books inspired by gaming as well as being a gaming content creator, posting reviews on my website and social media. I love the fast-paced feeling you get whilst gaming and wanted to echo that in my storytelling.

Janelle McCurdy Why did Janelle love this book?

It was effortlessly entertaining for me and had me gripped from the first chapter.

I'm very picky when it comes to books that are inspired by gaming because I want to feel that the author themselves are actual gamers too, and you can tell how much of a gamer Russell is, which made it extra special for me whilst reading. It was like watching the craziest esports match in book form! Fellow gamers you'll know what that means.

Karin Schönpflug Why did Karin love this book?

I found this new edition of Ursula Le Guin’s Earthsea collection at the airport in Milano while travelling to a conference for statisticians. Usually, I am quite snobbish about fantasy genres, as I prefer space aliens to wizards and dragons. Strangely, I still picked up the book, and it was of uttermost comfort to me in processing difficult life events.

Set in the beautiful landscapes of Earthsea, Le Guin discusses super hard topics such as matters of living and dying, grief and hope, aging and personal achievements, and desires, and the potential loss of an inhabitable world.

Book cover of Revan

Matthew Michaelson Author Of Daughters of Astrid

From my list on licensed books from settings that inspired me.

Why am I passionate about this?

All of the books I’ve recommended here involve various game series, or at least subseries in a larger franchise like Star Wars, that has come to influence my own writing, be it with the technology, the setting details, or just various writing quirks I’ve picked up over the years. I’m a long-standing fan of video games and strategy games or RPGs in particular, and I’ve been told in the past that my novels feel very video-game-y, though such was not my original intention. I should hope that the books I recommend here will give you some insight into what sources I draw from as I write my own novels!

Matthew's book list on licensed books from settings that inspired me

Matthew Michaelson Why did Matthew love this book?

While Star Wars was never the biggest franchise I was into growing up, the Knights of the Old Republic games served as my first proper foray into RPGs that have come to influence my books as a whole. Revan follows up on the titular character, set after the end of the first two Knights of the Old Republic games. Worries over his lost memories returning, Revan must seek out answers as to what drove him to go down the path of a Sith Lord in the first place, along the way meeting with Meetra Surik, the protagonist of the second game, following up on a rarely touched-upon point in the Star Wars universe of what happens when someone learns how to wield both the Light Side and Dark Side of the Force at the same time.

What is this book about?

There’s something out there:
a juggernaut of evil bearing down to crush the Republic—
unless one lone Jedi, shunned and reviled, can stop it.

Revan: hero, traitor, conqueror, villain, savior. A Jedi who left Coruscant to defeat Mandalorians—and returned a disciple of the dark side, bent on destroying the Republic. The Jedi Council gave Revan his life back, but the price of redemption was high. His memories have been erased. All that’s left are nightmares—and deep, abiding fear.

What exactly happened beyond the Outer Rim? Revan can’t quite remember, yet can’t entirely forget. Somehow he stumbled across a terrible secret…


Book cover of The Accidental Time Machine

Don Kinney Author Of The Darkdrift

From my list on sci-fi for newbies, from a newbie sci-fi writer.

Why am I passionate about this?

I’ve been fascinated by science and space since I was a child and naturally gravitated toward science fiction. In many respects, it was a form of escapism, as I didn’t enjoy school. I always preferred escaping into another world or being taken on a journey to another world. It wasn’t until I got older that I realized that most great science fiction is a commentary on our own world and the issues we face daily. Science fiction, more than any other genre, does a better job of exploring and dissecting aspects of our world, which in turn helps us better understand our world and our relationship with it.

Don's book list on sci-fi for newbies, from a newbie sci-fi writer

Don Kinney Why did Don love this book?

The Accidental Time Machine is one of the few novels that I’ve read beginning to end in one sitting because I found it so interesting. This isn’t the type of novel that will change your life or change how you feel about something. It’s just good. A good, fun book that can be read in a couple of hours. Haldeman doesn’t waste any time getting the story going and from there he takes you on a ride more enjoyable than novels twice the length.

Tonya Penrose Why did Tonya love this book?

I discovered famous journalist Ruth Montgomery’s books many moons ago.

She fearlessly began an odyssey into the "unknown," and I went along with her, reading book after book on this fascinating subject. Recently, her work flashed into my mind as I began writing my next novel. Since aliens and their visitations have captured the news, I felt compelled to read Aliens Among Us and see what Ruth shared back in the 1980s on this timely subject.

Her connections to powerful people add credence to her sharing, but the “other” sources she taps into fascinated me the most. The book begs a reader’s open mind, and today, I think that’s a reasonable request. 

Ruth Montgomery opened the door to explore the here and the hereafter. Aliens Among Us is, at the very least, thought-provoking, but for me, it gifted incredible insights. Ruth, wherever you are, you are missed and loved.

Book cover of Cosmic Jackpot: Why Our Universe is Just Right for Life

H. Chris Ransford Author Of In Search of Ultimate Reality: Inside the Cosmologist's Abyss

From my list on weird thrilling science universe.

Why am I passionate about this?

As a child, I felt profoundly dissatisfied by the pat and cardboard cutout explanations that some teachers offered for life and the universe: there had to be more! I decided to go into science. The explanatory power of science is 'next level,' to use a contemporary phrase, and unless and until we explore it, we'll miss the beauty and sheer wonder of the universe. Neither should we overly specialize: science is not compartmentalized, but vastly different fields of science feed into and reinforce one another. Popular science has an essential role to play: irrespective of how arcane hard science may appear to be, its story can always be told in everyday words.

H. Chris' book list on weird thrilling science universe

H. Chris Ransford Why did H. Chris love this book?

This book is the first pop science book I would ever recommend to anyone, and certainly to anyone who could only ever read one science book in their lives. It tackles the issue of why our universe is so extremely fine-tuned for life but ends up being much more than that, as the search for answers leads the author to a thrilling exploration of many deep questions at the forefront of physics and of life itself.  

Mind-blowing.

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

What is this book about?

Cosmic Jackpot is Paul Davies’s eagerly awaited return to cosmology, the successor to his critically acclaimed bestseller The Mind of God. Here he tackles all the "big questions," including the biggest of them all: Why does the universe seem so well adapted for life?

In his characteristically clear and elegant style, Davies shows how recent scientific discoveries point to a perplexing fact: many different aspects of the cosmos, from the properties of the humble carbon atom to the speed of light, seem tailor-made to produce life. A radical new theory says it’s because our universe is just one of an…


Book cover of Carl Sagan's Cosmic Connection

Ian Ridpath Author Of Star Tales

From my list on that have inspired my writings on astronomy and space.

Why am I passionate about this?

I am an author, editor, lecturer, and sometime broadcaster on astronomy and space. My early interest in the possibilities of extraterrestrial life and interstellar communication led me to write my first books, Worlds Beyond (1975) and Messages from the Stars (1978). This interest also led me to investigate UFO sightings, but I soon realized that their explanation lies in human misperception and not ETs. My investigation and explanation of the famous Rendlesham Forest UFO case of December 1980, widely regarded as one of the top-ten cases worldwide and sometimes known as Britain's Roswell, can be found hereIn conjunction with the outstanding Dutch celestial cartographer Wil Tirion, I have produced two standard observing guides for amateur astronomers. 

Ian's book list on that have inspired my writings on astronomy and space

Ian Ridpath Why did Ian love this book?

Carl Sagan was that most unusual of creatures: a top scientist who was also a lyrical writer. In an era when scientists were still wary of dealing with the press – an aversion that he helped overturn – his books were particularly influential in promoting the search for extraterrestrial life, both on the planets of our own Solar System (notably Mars) and on planets of other stars. In nearly 40 short, varied essays, The Cosmic Connection outlines our links with the cosmos around us, raises the possibility that we are not alone, and discusses what we might do if an extraterrestrial contact were to be received.

In 1973, Carl Sagan published The Cosmic Connection, a daring view of the universe, which rapidly became a classic work of popular science and inspired a generation of scientists and enthusiasts. This seminal work is reproduced here for a whole new generation to enjoy. In Sagan's typically lucid, lyrical style, he discusses many topics from astrophysics and solar system science, to colonization of other worlds, terraforming and the search for extraterrestrials. Sagan conveys his own excitement and wonder, and relates the revelations of astronomy to the most profound human problems and concerns: issues that are just as valid today as…
