Books like The Crucible of Time — picked by fans

My sister and I were only close because we’re only two years apart. But recently we’ve had some tragedy in our family, and that brought us closer.

While I was making this list of books, I was reminded of this story and how much I enjoyed it, not just for the prose, which I take notice of and will drop a book if it’s bad, but for that reminder of the brother and sister story here. Not to mention the rescue crew of odd characters which reflects a belief of mine: truth is universal.

Any human or alien can understand compassion and suffering and choose the better of the two.

What if reproduction required people to mate with another species—creatures more alien than bacteria?

In this book, Lilith Iyapo awakes after a nuclear war to find her alien saviors expect just that. The alien Oankali are organisms whose cells modify their own genes to perfection. But their genes run short of diversity, until they are compelled to share genes with a population as alien to them as—humans.

This disturbing novel asks us how much of our own humanity would we trade for survival? Would I welcome a half-alien child if its monstrous traits cured cancer? A science fiction novel that made me imagine the biological dilemmas of gene exchange.

This anthology has one of my favorite stories by Tiptree, it is called "We who stole the dream". The Joilani have long been enslaved and abused by humans. So has another race, of “delicately winged creatures”, whose sweat is a powerful intoxicant to humans. It is most potent when the donor experiences pain and fear, so humans have taken to torturing mated pairs of them, so the partners can watch each other suffer. The resulting sweat is a drug called Star Tears. Although that unnamed race plays no active role in the story, they are on my list because of the powerful manner in which they influence other species, invoking the darkest and most brutal aspects of human nature simply by existing.

The diminutive, weak, and peace-loving Joilani make a desperate break for freedom. Stealing a spaceship called The Dream, they seek out the mythical planet of their… show more.

Years before Game of Thrones became a household name, Martin was best known for this hauntingly beautiful and deeply disturbing novella. Two telepaths, Robb and Lya, are sent to an alien planet to investigate a disturbing religious movement. The planet is home to a race called the Shkeen, and to a gelatinous parasite called the Greeshka. In middle age the Shkeen allow the Greeshka to infect them, and ten years later they visit a cave where they allow a massive specimen to consume them. Some humans living on the planet have even joined the native religion, and have allowed themselves to be infected and devoured. The administrators are desperate to know why.

Robb and Lya have an unusually close relationship, but she suffers from a sense of isolation that telepathy cannot banish. While they watch some Shkeen being devoured by the Greeshka, she can sense how isolated the Shkeen feel… show more.

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.

Sterling burst onto the SF scene with a crash and clatter when I was in high school, and this book, while perhaps not his very best work, is certainly his most creative.

I loved the fact that the aliens were investors rather than conquerors and also the fact that human beings were diverging along so many different vectors that we were rapidly becoming alien to one another.

An absolute achievement of imagination, Torishima’s collection of novellas and novelettes is set in a future in which humans, machines, and alien life are as intertwined as the stories themselves. Attempting to sum up the various horrifying, chaotic and enigmatic worlds of this book is a fool’s errand; its breadth is staggering and can only be read to be understood. Even then, you will likely be left with more questions than answers. Sisyphean stretches itself to the breaking point and then challenges the reader to keep going, to open one’s mind to a torrid future populated by creatures who retain their humanity, but little else. Thankfully, Torishima offers his own illustrations to help you along.

One of my favorite living writers is Rachell Powell. She writes on animal ethics, genetic engineering, and invertebrate intelligence, among other topics.

Powell’s brilliant 2020 book can be seen as a spiritual sequel to Gould’s aforementioned 1989 Wonderful Life. Hence, it makes sense to include both on the list. Powell takes Gould’s experiment on “replaying the tape” and updates it, given modern knowledge, while also establishing its relevance for the cutting-edge scientific field of astrobiology.

Astrobiology is the study of what we should look for when we look for signs of life beyond Earth. It’s a burgeoning field at the frontier of human knowledge, poised to provide revelatory knowledge about our own fate and future, regardless of whether the results of the search for extraterrestrial life are positive or negative. 

Assessing the role of chance in governing the course of biological evolution—whether here or elsewhere in the universe—is, as… show more.

I originally picked up this book because I really like the author. Seanan McGuire never disappoints. Parasite is part one of a series, and is a completely fresh take on what some people might call zombies (although there is a lot of room for speculation there). The characters were compelling, and the plot kept me reading when I should have been doing countless other things. I love everything I’ve ever read by McGuire (alternate pen name Mira Grant), and this book was no different.

This book left me questioning what it truly means to be human. From the moment Logan Ramsay was infected with a mysterious virus, I was captivated by Crouch’s exploration of genetic enhancement. As Logan's abilities expanded—making him smarter, stronger, and more detached—I was both fascinated and horrified.

The tension between his new capabilities and the erosion of his emotional connections made the ethical dilemmas even more poignant. Crouch’s vision of a world on the brink of extinction, with genetic upgrades as both a salvation and a curse, felt disturbingly real. This isn’t just a techno-thriller; it’s a profound examination of what we might sacrifice in the relentless pursuit of progress.
