The most recommended hard science fiction books

Where to begin...I loved everything about the Murderbot diaries, from the snarky, neurodivergent-coded main character, to the brilliant writing, to the fast-paced plot and thrilling action sequences, to the beautiful exploration of what it means to be human and what it means to care about people and find people who care about you. I loved the moral complexity of the world, where there were very few "good guys" and "bad guys" and a whole lot of people who are mostly just trying to do their best and get by in a world that isn't always kind. And maybe most of all I loved the relationships--the deep, real friendships between people who know all the weird, quirky, annoying parts of each other and love each other anyway. This is my new comfort read, and I'm so happy I found it.

You and I may already have one foot in this near-future world with its chilling look inside the warehouse of a retail giant: Amaz… uh, Cloud. The company is named Cloud. Can powerful bosses possibly be benign overlords? Is a miserable existence good enough in a wretched world? Hmm, maybe not.

I loved the characters – a reluctant hero and a cold-blooded spy who join forces as an unlikely couple searching for the truth behind a colossal global company. I never guessed the ending, and that's always a plus.

In a cancer research lab, a young scientist thinks he might have found a cure for cancer. But his colleague, who just happens to be his ex-girlfriend, is convinced there are flaws in his work.

I loved the way this novel evokes the reality of scientists’ lab work and their struggles to try and determine what is ‘really’ going on. Too often, science is presented in the media as a straightforward yes-no/right-wrong pursuit, whereas in reality, it’s messy and full of dead ends. This novel portrays scientists as human beings who bring their own passions and prejudices into the lab, which struck me as all too relatable.

This might seem a bit off-message because Pohl dropped out of college before finishing his science degree. But he did work as a weather forecaster in the US Navy. And I can’t resist including this book, because it deals with the area of science closest to my heart – many worlds, or parallel universes. The existence of these other worlds next door to our own is the best scientific explanation of the mysteries of quantum physics, such as the famous puzzle of Schrödinger’s Cat, and Pohl wraps it all up in entertaining fashion with a story of what happens when those worlds interact. The fact that Pohl includes a version of myself (actually, several versions of me) in the story has no bearing on my choosing it. I repaid the compliment by including him as a character in my story “Untanglement”, included in my anthology Don’t Look Back' ;-).

I once witnessed, at a science-fiction convention, Isaac Asimov and Harlan Ellison debate esoteric matters to the delight of fans. The Naked Sun deals with such matters. Earth detective Elijah Baley, assisted by robot Daneel Olivaw, investigates the death of Rikaine Delmarre, a prominent scientist. Delmarre died in unusual circumstances at his estate on the planet Solaria. In the 48th century, mankind has adapted to life in a variety of suns. Solaria’s population is sparse, and robots vastly outnumber humans. People avoid personal contact and live on distant estates, alone or with their spouses. Solarians customarily communicate remotely by holographic viewing. Baley and Olivaw have a puzzling assignment because except for Delmarre’s wife and house robots, considered incapable of murder, no one was at the estate at the time.

The book hooked me, and I couldn’t stop until I read the whole series. I loved the realistic future world, that is both hopeful and full of challenges; great, flawed characters who have depth and feel real; tight storytelling and fast pacing. 

It’s a terrifying world ravaged by climate change and pandemics, where everyone has lost someone. However, it’s also a world I desperately want to live in, where actual leaders who care are in positions of power. Where people live in tightly-knit communities, and no one is truly alone. Where humanity has the collective power to change things for the better. It's such a beautiful vision that it made me cry. The book shows that we still have a chance. It offers a vision of humanity finally working together to overcome our biggest challenges.

Software is a zany romp through a 1983 vision of 2020, with sapient AIs living on the moon and maybe invading South Florida. 

Like its author, Software is a rich amalgamation of disparate elements: on the one side, the book is campy fun, while on the other, it’s a legitimate exploration of Artificial Intelligence and identity.  Back when I was first getting into cyberpunk, this was another difficult find, despite having won the Philip K. Dick award; I actually didn’t read it until the late ‘90s! 

The author’s life is nearly as interesting as his books, too: his full name is Rudolf von Bitter Rucker, a descendant of German philosopher Georg Friedrich Hegel, though he grew up in Louisville, KY, and he would eventually develop his own literary movement, Transrealism.

What if we get it wrong? What if the scale and pace of our collective measures to address climate destabilisation and the biodiversity crisis remain insufficient?

Oreskes and Conway provide the imagined view of a historian of the “Second People's Republic of China” from 2393. His account describes how the political and economic elites of the early decades of the twenty-first century ignored or dismissed the clear warnings of climate catastrophe.

Soaring temperatures, rising sea levels, drought, and mass migrations resulted in “The Great Collapse of 2093”. Three centuries later as the world emerges from the “Penumbral Age’ it is a more subdued and thoughtful place. 

By dramatizing an all-too-plausible ‘ghastly’ outcome, the authors seek to galvanise the energies of readers to rise from their armchairs and act. We should all strive to ensure that the book remains firmly on the shelves of fiction.

Lady astronauts are all the rage these days, but what would it have taken to get women into spaceships in the notably more misogynist 1950s? According to this book, it would take the threat of a world-destroying cataclysm—which sounds about right.

This book doesn’t stop at sexism, though. It tackles a variety of -isms, and doesn’t hold back in showing how absurd it would be to hold onto them as the world burns. Some critics have even suggested that there are too many types of bigotry on display here, to which I would reply, “Dude, wait ‘till you hear about real life.”

Ignore all the yucky, uncomfortable stuff if it pleases you, though, and this will still be a fascinating look at mid-century America, but with ladies in space.

I found this book to be a fascinating science-fiction pandemic thriller that covers an epic time scale and some really crazy ideas. The writing captured my attention quickly, and I found this story to be an intense read. The plot surfaced moments in my imagination where I couldn’t help but question the likelihood of these events happening in our modern-day world.

I also relate to Christopher Dicken (the protagonist), a virus hunter who makes an unbelievable discovery. His attempts to uncover the truth about human evolution and save his family against what seems like every power on earth felt very real to me. It’s a wild story that has stuck with me over the years, and it’s definitely worth reading again.
