Book cover of Dawn

Rachel Mundy Author Of Animal Musicalities: Birds, Beasts, and Evolutionary Listening

From my list on having a voice if you’re not (fully) human.

Why am I passionate about this?

When I was a doctoral student in historical musicology, I went to Paris to study postwar government budgets for music, but it was really boring. So I started hanging out listening to Parisian songbirds instead. The more I learned about birdsong, the more I realized it raised some really big questions, like why biologists and musicians have completely different standards of evidence. Those questions led me to write my book, which is about what it means to sing if you’re not considered fully human, and most of my work today is about how thinking about animals can help us understand what we value in those who are different.

Rachel Mundy Why did Rachel love this book?

Butler is known for bringing a black, feminist, and queer perspective to science fiction, a genre of futuristic and outer-space storytelling that traditionally features white male protagonists.

But what really captivates me about this book, which is set in a post-apocalyptic future where human survivors are mated with their alien rescuers (really!), is the way it asks icky-yet-intensely-meaningful questions. What does it mean to “be human” in a future of genetic hybridity and gender fluidity? What does it mean to love a partner or children whose genetics and culture are radically different from your own? When is violence futile, and when is it the only way to be heard?

I’m pretty much obsessed with this book, and I promise that any reader who has thought deeply about what it means to be really different will love it too.

Book cover of Extraterrestrial: The First Sign of Intelligent Life Beyond Earth

Stephen P. Maran Author Of Astronomy for Dummies

From my list on space from someone with 35 years at NASA.

Why am I passionate about this?

I’ve studied space for 60+ years, including spotting Sputnik from atop 30 Rock for Operation Moonwatch; monitoring an exploding star for a PhD at University of Michigan, leading the Remotely Controlled Telescope project at Kitt Peak National Observatory, hunting pulsars from Arizona and Chile, and helping develop scientific instruments for the Hubble Space Telescope. I worked for 5 years at Kitt Peak and 35 years for NASA. As Press Officer (now retired) of the American Astronomical Society, I organized press conferences on many notable cosmic discoveries. Minor Planet 9768 was named Stephenmaran for me, but I haven’t seen it yet. What I have spotted are five exceptional books on space.  Enjoy!

Stephen P. Maran Why did Stephen love this book?

The first known object from interstellar space, ʻOumuamua, plunged through the solar system and headed out again in 2017. It was seen by telescopes for just 17 days, enough to tell that it wasn’t as the saying goes, a bird, a plane, or Superman. Perhaps it was a space vehicle or other artifact from distant aliens, an older and superior civilization than ours. At least that’s what the brilliant Harvard astrophysicist Avi Loeb suggests. I think his theory is soundly based on the limited observational data, but that doesn’t make it true, and other astronomers won’t touch aliens with a ten-foot telescope. They offer alternative explanations none of which clearly fit the data but that smack less of science fiction. Inquiring minds should read the book and decide for themselves.

This book, by one of the greatest thinkers of the 20th century, offers a personal insight into understanding and appreciating the vastness of the Cosmos. It’s a book that spans so much and paints the most accurate picture I’ve read of how we might fit into the Universe.

Book cover of Star Trek: Picard: Rogue Elements

Bernd Perplies Author Of Star Trek Prometheus: Fire with Fire

From my list on Star Trek novels that will warp you into hyperspace.

Why am I passionate about this?

I’ve been a Star Trek fan and storyteller all my life. The first stories I wrote at school, the first Star Trek episodes I watched as The Next Generation debuted on German TV. Many years have gone by since then. I watched hundreds of Star Trek episodes and professionally penned dozens of fantasy and science fiction novels for children and adults, like Drachengasse 13 (“Dragon’s Alley 13”, not translated) or Der Drachenjaeger (“Black Leviathan,” Tor Books). The culmination of both being a fan and a writer came in 2016 when, with Star Trek: Prometheus, I was allowed to add my own small part to the ever-growing Star Trek literary universe.

Bernd Perplies Why did Bernd love this book?

Honestly, I couldn’t put this book down. I read Rogue Elements during a summer vacation on a lovely North Sea island and I had to force myself to have a break and go out for some bicycling and beach fun.

John Jackson Miller just had me hooked with his tale of dashing (but also sad and often drunken) ex-Starfleet officer Cristóbal Rios – introduced in Star Trek: Picard – living through a hilarious adventure while at the same time trying to find a new purpose in life after being cashiered out of his career because of some fishy diplomatic affair.

Grumpy gangsters, a dangerous woman, strange new crew members, and the hunt for a secret treasure keep Rios on the run throughout the whole novel.

A thrilling untold adventure based on the acclaimed Star Trek: Picard TV series!

Starfleet was everything for Cristobal Rios-until one horrible, inexplicable day when it all went wrong. Aimless and adrift, he grasps at a chance for a future as an independent freighter captain in an area betrayed by the Federation, the border region with the former Romulan Empire. His greatest desire: to be left alone.

But solitude isn't in the cards for the captain of La Sirena, who falls into debt to a roving gang of hoodlums from a planet whose society is based on Prohibition-era Earth. Teamed against…


Book cover of The Gentle Giants of Ganymede

Wil Mccarthy Author Of Beggar's Sky

From my list on peaceful alien contact.

Why am I passionate about this?

I’ve been a science fiction writer since I was old enough to read, and I’ve spent probably way too much of my life reading and writing and researching and thinking about aliens. I’ve worked in the aerospace industry, launching rockets to the moon and Mars and Saturn, and five of the books I’ve published have touched on alien life in one way or another. I’ve worked as a contributing editor for WIRED magazine and the science and technology correspondent for the SyFy channel, and I hold patents in seven countries, including 31 issued U.S. patents.

Wil Mccarthy Why did Wil love this book?

This was the first book I ever owned that was signed by the author. As a young teenager, I was struck by the cover art and absolutely floored to find out that my father actually knew James P. Hogan from their time together at Digital Equipment Corporation.

The book’s workman-like prose was perfect for my impressionable mind and has stuck with me for over four decades.

What is this book about?

Long before the world of the Ganymeans blew apart, millennia ago, the strange race of giants had vanished. All that remained of them was a wrecked ship, abandoned on a frozen moon of Jupiter. Now Earth's scientists were there, determined to ferret out the secret of the lost race. Then suddenly the Ganymeans returned, bringing with them answers that would alter all Mankind's knowledge of human origins . . .


Book cover of Freedom's Landing

Athena Author Of Murder of Crows: Book One of the Pillars of Dawn

From my list on when destiny calls, and love answers.

Why am I passionate about this?

I have a passion for the topic because it’s so unlimited. We’re all called to destiny inner/outer in so many ways. We see a lot of stories about those calls being massive adventures with global impact—but sometimes the small stories, those inner calls with inner love answers are just as epic, just as magnificent. Love of family, community, country, lovers, nature… truly, it can be anything. These are just a few books off the older shelves to illustrate the many ways love answers the call. My challenge is to go back and re-read them with this list in mind. Re-visit books from a decade ago, reframe the story with love.

Athena Why did Athena love this book?

This one might seem an odd pick at first. I thought so too when a friend gave me a copy. I was surprised there was an Anne McCaffery book I hadn’t read!

This book belongs on the list for its beautiful depiction of what love and community can do for a group of mismatched outcasts, refugees on a dangerous planet—a collection of peoples all very different from one another working together to survive.

Their destiny was to become a cohesive extended family despite all their differences, and to become empowered individuals at the same time. There’s a steamy romance, too. So that’s always yummy. It goes to show that when destiny calls, the love that answers can be with a voice of multitudes.

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 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.

A hilarious and innovative picture book from award-winning author and illustrator Colin McNaughton.


Book cover of Old Man's War

Steven Decker Author Of Time Chain

From my list on sci-fi that generates emotion.

Why am I passionate about this?

My love of reading was born on the day my 5th-grade teacher handed me a book of poetry; my “punishment” for throwing a spitball. I was to memorize “Stopping By Woods on a Snowy Evening” and recite it publicly the next day. I was mesmerized by the poem, because it drew a picture in my mind, and filled me with great emotion. As an 8th grader, I read the entire Lord of the Rings trilogy, for fun, then moved on to the great classics by Asimov and Heinlein. I wrote my first novel in 1988, but Time Chain is my first Sci-Fi novel, with more on the way.

Steven Decker Why did Steven love this book?

I was moved from the opening lines of Old Man’s War. An ordinary man of 75 visits his wife’s grave, then joins the army. What? Oh yeah, now I understand. Mind uploading is integral to this book, first published in 2005, and it will soon be the rage in the real world of our near future. In Old Man’s War we experience mind uploading through the character, John Perry, and other new recruits. Then we fight. Perry becomes a war hero, and he crosses paths with his wife along the way. What? I thought she was dead? Oh yeah, now I understand. She was grown from Kathy Perry’s DNA, but she has no memory of John. Or does she? Military sci-fi adventure blooms into a love story? Wow, this could be a series. Oh, wait. It is!

What is this book about?

Perfect for an entry-level sci-fi reader and the ideal addition to a veteran fan’s collection, John Scalzi's Old Man’s War will take audiences on a heart-stopping adventure into the far corners of the universe.

John Perry did two things on his 75th birthday. First he visited his wife's grave. Then he joined the army.

The good news is that humanity finally made it into interstellar space. The bad news is that planets fit to live on are scarce-and aliens willing to fight for them are common. The universe, it turns out, is a hostile place.

So: we fight. To defend…


Book cover of The Crucible of Time

C. S. Friedman Author Of This Alien Shore

From my list on aliens in science fiction.

Why am I passionate about this?

I have always been fascinated by the workings of the human mind. What instincts and influences make us who we are? This Alien Shore grew out of research I was doing into atypical neurological conditions. It depicts a society that has abandoned the concept of “neurotypical”, embracing every variant of human perspective as valid and valuable. One of my main characters, Kio Masada, is autistic, and that gives him a unique perspective on computer security that others cannot provide. What might such a man accomplish, in a world where his condition is embraced and celebrated? Good science fiction challenges our definition of “Other,” and asks what it really means to be human, all in the context of an exciting story.

C. S. Friedman Why did C. S. love this book?

A planet in its equivalent of the stone age is passing through a galactic debris field. An alien stargazer realizes that sooner or later some object will strike the planet and destroy it. The only hope of survival his species has is to leave the planet before that happens. But the concept is a mere abstraction to his people, the equivalent of a Neanderthal saying “we need to travel to the moon,” and the task is further complicated by the fact that their technology is biological in nature, focused on the manipulation of living tissue. It is hard to imagine how such technology could ever produce a spaceship. 

The novel--structured as a series of novellas-- follows the development of a fascinating alien species from its primitive roots to an age of high technology, each chapter focusing on a different time period. Always the stargazer’s warning is proclaimed by a few…

Book cover of Galax-Arena

R. Ann Humphries Author Of Sedich: The Annals of Lusiartha

From my list on YA to satiate your travel bug.

Why am I passionate about this?

I’m a YA fantasy writer, and I’ve been addicted to stories of adventure for as long as I can remember. My love of story filled me with a heart for other worlds and realms and a fondness of reading things that challenged my heart and mind here in the real world. Stories are what make us human, and we storytellers are tasked with challenging readers’ assumptions about how the world, life, love, and humanity works. My obsession with story-telling led me to write my YA fantasy series The Annals of Lusiartha

R.'s book list on YA to satiate your travel bug

R. Ann Humphries Why did R. love this book?

As a big sci-fi fan, I often loved exploring the idea of what would happen if the human race ever met aliens. In Galax-Arena, three children are kidnapped and forced to perform death-defying circus stunts in order to entertain their captors. Not only does the story contain some riveting descriptions of acrobatic feats and tricks, the story explores fascinating concepts of slavery, trust, and what it means to be a child in comparison to an adult.

What is this book about?

Before The Hunger Games—even before Battle Royale—there was the Galax-Arena, where children are pitted against each other for the benefit of a shadowy audience that feeds on their fear. A Children's Book Council of Australia Honour Book for Older Readers, Galax-Arena is a dark, uncompromising thriller and a cult classic.Joella, her brother Peter and her sister Liane, are kidnapped and transported to become entertainers for an alien species. Many of the performing children are desaparecidos—the disappeared—kidnapped from third world slums and chosen for their extraordinary gymnastic ability. For the children, there is only one escape from the Galax-Arena: out of…
