The best science fiction books with worlds that may as well be characters

It took me two reads to actually like this book, which is probably not the best way to start this, but in Ursula K. Le Guin, we trust. This book is fascinating not just in content but also set up, as its chapters always follow the main character, Shevek, but alternate between two timelines spent on either the lush planet Urras or its desolate moon Anarres.

I loved the juxtaposition of the two and how the book challenged me to see all the similarities hiding beneath the glaring differences between these worlds and their people. Le Guin is unafraid to explore so many different kinds of societies here, and I always recommend this book to friends looking for a “thinker” sci-fi novel.

I toyed with recommending a different book by Adrian Tchaikovsky for this but ultimately went with this one because it is one of the most wildly imaginative books I’ve ever read. Tchaikovsky could have settled for speculating on one or two different evolutionary alternate histories of Earth, but nah. He went for ten.

I was so drawn into the way he developed societies around which species had become the surviving dominant in each timeline, from the trilobites to the rodents and everything in between. This book takes the question “What if?” and chucks it out the window with the strength of an Olympic shot put athlete without sacrificing raw character, emotion, and connections. I loved every page.

Brandon Sanderson hardly needs an introduction as one of the modern-day heavy hitters of sci-fi and fantasy. This book, though, has a wonderfully creative setting, with a world plagued by sunlight so intense it’s only livable in the thin band of twilight that preludes the dawn.

One of my favorite things about science fiction is when an author creates a fantastical world that has deeply impacted the shaping of its society, from the rulers to the rebels and everyone in between. Sanderson delivers on this front, and I love how integral its setting is to its plot and the development of its characters.

This is easily one of the funniest books I’ve ever read, but this novel (and the series as a whole, although I have mixed feelings about the later books) contains some of the most imaginative places, species, inventions, and characters I’ve ever seen.

Even some of the one-off side characters that are little more than a passing joke are obnoxiously original and could star in their own stories as easily as Arthur Dent does in this one. I’m hard-pressed to think of a more creative, absurd, and wide-reaching book than Hitchhiker’s Guide.

Imagine a world sliding into a climate apocalypse… and society just shrugs. This is an anxiety-inducing book, and another one that I had to read twice before I fully appreciated it, but it’s also one of the smartest books that speculates on climate change and just how much that could impact society around us.

I find this book thought-provoking and frustrating because I see these brilliant characters making selfish decisions that feed a self-destructive world, and this novel has only grown more relevant as the years have passed. Margaret Atwood doesn’t like to think of this as science fiction, but I can’t think of a better book to hold up a mirror to the world as we know it and then invite us to look beyond.
