Book cover of The Glass Universe: How the Ladies of the Harvard Observatory Took the Measure of the Stars

Fernando J. Ballesteros Author Of E.T. Talk: How Will We Communicate with Intelligent Life on Other Worlds?

From my list on humanistic answers from the skies.

Why am I passionate about this?

I am an astronomer and astrobiologist, and my field of work leads me to wonder about the origin of life in the universe and how scientific discoveries (and especially those related to space) affect culture, people's lives, or even civilization itself. All of the books listed here focus precisely on answering some of these concerns, which is why I find them extremely interesting.

Fernando's book list on humanistic answers from the skies

Fernando J. Ballesteros Why did Fernando love this book?

I find it a lovely book that highlights the work of many hidden figures in the field of astronomy for the mere fact of being women. The book shows the groundbreaking work of a group of women astronomers at the Harvard College Observatory in the late 19th and early 20th centuries, who made significant contributions to the field of astronomy.

I always find Sobel's prose fascinating and very enjoyable to read; I love the way she writes. Drawing from letters, diaries, and scientific papers, Sobel paints a vivid portrait of these pioneering women and their remarkable discoveries. Reading the book is like being present in that time.

Fernando's book list on humanistic answers from the skies

Fernando J. Ballesteros Why did Fernando love this book?

I like this book because it challenges conventional scientific thinking, advocating for a more open-minded and exploratory approach to scientific inquiry.

I find it interesting because it delves into various scientific disciplines, from physics to biology, highlighting instances where entrenched dogma and ignorance have hindered progress. It argues for the necessity of questioning established paradigms and embracing curiosity-driven research to foster genuine innovation.

As I’m interested in the intersection of philosophy, history, and science I find this book very compelling, as it offers fresh perspectives on how scientific breakthroughs occur and the importance of intellectual humility in the pursuit of knowledge.

1 author picked The Reinvention Of Science as one of their favorite books, and they share why you should read it.

What is this book about?

Throughout the history of science, different thinkers, philosophers and scientists postulated the existence of entities that, in spite of their not being visible or detectable in their time, or perhaps ever, were nevertheless useful to explain the real world. We started this book by looking at a handful of these entities. These included phlogiston to account for fire; the luminiferous ether for propagation of radiation; the homunculus to provide for heredity; and crystalline spheres to carry the wandering planets around the earth. Many of these erroneous beliefs had held up progress, just as dragons drawn on the edges of a…

Fernando's book list on humanistic answers from the skies

Fernando J. Ballesteros Why did Fernando love this book?

One of my favorite topics is space exploration and the future of humanity on other stars. Will we ever be able to travel to Proxima Centauri (the closest star) and settle there? Is this type of interstellar travel feasible? The book is a dose of reality on this matter, exploring the possibilities and challenges of interstellar travel.

The book delves into propulsion methods, spacecraft designs, and the potential for human exploration beyond our solar system. The result is, in my point of view, an optimistic book that allows us to dream of a future among the stars.

Fernando's book list on humanistic answers from the skies

Fernando J. Ballesteros Why did Fernando love this book?

This book tries to answer one of those vital questions that we have asked ourselves since we were children and that, at least in my case, continues to be part of my interest as an adult: Why don't we have any real proof of the existence of other civilizations beyond Earth?

This question has its own name: the Fermi Paradox, the apparent contradiction between the high probability of extraterrestrial life and the lack of evidence for alien civilizations. I enjoyed how the author, Stephen Webb, goes over all the possible solutions to this paradox that science has been able to imagine. In the end, Webb gives his own solution (which does not match mine).

By Stephen Webb,

Why should I read it?

1 author picked If the Universe Is Teeming with Aliens ... WHERE IS EVERYBODY? as one of their favorite books, and they share why you should read it.

What is this book about?

Given the fact that there are perhaps 400 billion stars in our Galaxy alone, and perhaps 400 billion galaxies in the Universe, it stands to reason that somewhere out there, in the 14-billion-year-old cosmos, there is or once was a civilization at least as advanced as our own. The sheer enormity of the numbers almost demands that we accept the truth of this hypothesis. Why, then, have we encountered no evidence, no messages, no artifacts of these extraterrestrials?

In this second, significantly revised and expanded edition of his widely popular book, Webb discusses in detail the (for now!) 75 most…


Book cover of Star Wars The High Republic: Into The Dark

Ben Green Author Of Forged in the Fallout

From my list on YA with boys who defy stereotypes.

Why am I passionate about this?

I’m a grown man who reads and writes young adult fantasy books. I believe YA stories are perfect for nearly every audience. Let me tell you why. Our teenage years are filled with growth. As we mature, we forget what such rapid change feels like. We become less empathetic toward youth. And yet, many of our characteristics—positive and negative—develop during these years. I read YA to understand myself. It also helps me be a more understanding father and teacher. That said, I'm very picky. I despise teenage stereotypes. For young men, it is particularly hard to find books that depict empathetic male characters. Here’s a list of books where young men feel genuine.

Ben's book list on YA with boys who defy stereotypes

Ben Green Why did Ben love this book?

Reath Silas is a very relatable Jedi, though perhaps not the most heroic at first.

He deeply doesn’t want to leave the comfort of his home on Coruscant, especially for his first assignment in the outer rim. He would rather explore the Jedi archives and attend historiography. Maybe, like Anakin Skywalker, he too dislikes sand. But reluctantly he faces the challenge.

When his group’s ship is pulled out of hyperspace, they take refuge in an abandoned space station. Reath is thrust into a world of pirate looters, shady guild members, and a dark-side mystery concerning the station itself.

What lessons will this young padawan learn?

1 author picked Star Wars The High Republic as one of their favorite books, and they share why you should read it. This book is for kids age 12, 13, 14, and 15.

What is this book about?

Long before the Clone Wars, the Empire, or the First Order, the Jedi lit the way for the galaxy in a golden age known as the High Republic!

Padawan Reath Silas is being sent from the cosmopolitan galactic capital of Coruscant to the undeveloped frontier-and he couldn't be less happy about it. He'd rather stay at the Jedi Temple, studying the archives. But when the ship he's traveling on is knocked out of hyperspace in a galactic-wide disaster, Reath finds himself at the center of the action. The Jedi and their traveling companions find refuge on what appears to be…


Book cover of Zoe's Tale

Dan Rice Author Of Dragons Walk Among Us

From my list on YA fantasy and sci-fi with diverse perspectives.

Why am I passionate about this?

As an author of young adult fantasy and science fiction, I’ve read many books that fall within that rubric. This list captures the most exciting young adult novels I’ve read over the past few years. All have aspects of storytelling and themes I strive to capture in my writing. One thing I love about the young adult genre is the characters go on an adventure full of excitement and danger. The adventure is a metaphor for growing up. So if reads chock-full of death-defying odds, mystery, wonder, and a sprinkling of romance are your jam, the books in this list are for you.

Dan's book list on YA fantasy and sci-fi with diverse perspectives

Dan Rice Why did Dan love this book?

Scalzi transports us to his ever-exciting Old Man's War universe for a retelling of the novel The Last Colony from a teen's perspective. Aliens, adventure, and young love abound in Zoe's Tale, a story sure to delight Scalzi fans and is an excellent entry point for young adult readers interested in his brand of witty sci-fi.

With Zoe's Tale, Scalzi demonstrates one key to a compelling story is a fantastic protagonist. Zoe is just that. She is engaging, stubborn, snarky, a true friend, an angsty teen, and brave. Readers who enjoy Scalzi's clever prose will find the fact Zoe's Tale is a retelling of The Last Colony immaterial. That's how captivating a character Zoe is.

What is this book about?

Hard-core, fast paced science fiction, John Scalzi's Zoe's Tale is the fourth in The Old Man's War series.

Dan's book list on YA fantasy and sci-fi with diverse perspectives

Dan Rice Why did Dan love this book?

I was blown away by how good Victories Greater Than Death is. It reminds me of the original Star Trek with its optimism and inclusiveness. Charlie Jane Anders puts inclusiveness front and center with the sheer diversity of her characters in ethnic origin, neurodiversity, and LGBTQA+ identification. This is done brilliantly in a manner that is in your face, lighthearted, touching, and nuanced. All this is accomplished without sacrificing the yarn's sci-fi suave.

The protagonist is Tina, a teenage girl destined to transform into an alien superhero. Her story thrums with fantastical adventure while exploring questions of identity and purpose with gravitas. I explore similar themes in my writing and hope I handle them with the aplomb Charlie Jane Anders does.

Outsmart Your Enemies. Outrun the Galaxy.

“Just please, remember what I told you. Run. Don’t stop running for anything.”

Tina never worries about being 'ordinary'--she doesn't have to, since she's known practically forever that she's not just Tina Mains, average teenager and beloved daughter. She's also the keeper of an interplanetary rescue beacon, and one day soon, it's going to activate, and then her dreams of saving all the worlds and adventuring among the stars will finally be possible. Tina's legacy, after all, is intergalactic--she is the hidden clone of a famed alien hero, left on Earth disguised as a…


Book cover of Old Man's War

Bennett R. Coles Author Of Virtues of War

From my list on military sci-fi books that actually understand what it feels like to be in the military.

Why am I passionate about this?

I was 4 years old when I first saw Star Wars, and it changed my entire world view. Basically, from that moment forward everything was cooler if it was in SPACE! Eventually, I grew up, and today, I’ve served more than 20 years in uniform, but I discovered along the way that most sci-fi doesn’t portray the military accurately. When I started writing, one of my goals was to present as realistic a depiction of the military as I can (in space!) and I’ve always enjoyed books like the ones on my list that do the same. 

Bennett's book list on military sci-fi books that actually understand what it feels like to be in the military

Bennett R. Coles Why did Bennett love this book?

The premise of Old Man’s War is basically every old man’s fantasy (no… not what you think). But if there really was a way to combine the wisdom of age with the virility of youth, I think we’d all be on board.

From a military point of view, it does a great job of bringing a civilian through the recruiting and basic training process without resorting to the trope of a wide-eyed, innocent youth who finds his strength.

In this case, our recruit already comes with a lifetime of experience and his observations of military training and philosophy are pithy, grounded and very entertaining. It’s a fresh look at basic training and it goes a long way to explain why recruits are trained the way they are.

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 Halo: The Fall of Reach

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?

The Halo Universe is a massive, sprawling sci-fi series that many assume to be just a random sci-fi shooter franchise. The Fall of Reach acts as a prequel to the first game and to the Halo series as a whole. Focusing on the initial creation of the Spartan-II Super Soldier program, the growth of Spartan John-117 into a super soldier, and culminating in the defense of the planet he’s grown up on, The Fall of Reach serves to set the stage for the Halo franchise. I recommend picking up the reprints from 2011 or later, as it fixes many continuity errors induced later on in the series.

Book cover of Ciaphas Cain: Hero of the Imperium

Andrew Claydon Author Of The Simple Delivery

From my list on fantasy and sci-fi to make you laugh.

Why am I passionate about this?

For me the best fantasy and sci-fi is made up of many themes. Take one of my favorite fantasy movies, Willow. It has heart and comedy but also drama, action, and high stakes. This is something that I want from my writing. I want the reader to laugh, and a few paragraphs later be gasping as the main character faces mortal peril. With the very best books, you get taken on a roller coaster of emotional responses. As a UK fantasy author, my goal is to make sure that you put my books down only when you absolutely have to, which includes falling asleep holding them because you’ve stayed up too late reading.

Andrew's book list on fantasy and sci-fi to make you laugh

Andrew Claydon Why did Andrew love this book?

Nothing about the Warhammer 40,000 universe says ‘funny’. The fact that it’s fans call it the ‘grimdark’ is a proud testament to this. I’ve read a lot of Warhammer books, but was surprised when I came across this series. It follows Ciaphas Cain, a Commissar who is trying to survive and find the cushiest job for himself in a universe of constant war, yet somehow, he constantly ends up being the hero.

This book really opened my eyes to the fact that you can humor even in the grittiest settings, and that just because a book is funny, it doesn’t mean it can’t be action-packed and have high stakes. Much of the humor comes from Cain’s futile attempts to avoid any sort of combat and save his own skin.

By Sandy Mitchell,

Why should I read it?

2 authors picked Ciaphas Cain as one of their favorite books, and they share why you should read it.

What is this book about?

The first three action-packed adventures of Commissar Ciaphas Cain, and his malodorous aide Jurgen are collected together into one amazing volume. His brand of sarcasm and self-preservation are a hit with Black Library fans and provide a unique counterpoint to the usual darkness of the Warhammer 40,000 universe.
