13 Mind-Bending Hard Science Fiction Books by Women

These great reads prove hard sci-fi isn't just a man's game.

Hugo Award winners 2018

For years, so-called “hard sci-fi” – that is, science fiction that relies on credible science over speculative leaps or “hand waving” – has been seen as something of a boys club. 

But women have been writing hard science fiction for as long as the (sub)genre has been in play. Even Mary Shelley’s Frankenstein relied on then-cutting-edge scientific theory.

As a result, there are plenty of fascinating and thought-provoking books by women that are every bit as scientifically rigorous as those written by their male counterparts – if not more so. From Hugo and Nebula Award-winners to lesser-known gems, these hard sci-fi books by women will make you think, and keep you turning the pages. 

Playing God

Playing God

By Sarah Zettel

Many sci-fi and fantasy novels revolve around winning a war. Sarah Zettel’s Playing God is all about ending one. 

The swan-like inhabitants of the planet Dedelphi have been at war for centuries, and if something doesn’t change soon, there won’t be much left. 

In a last-ditch bid for peace, they ask for outside mediation, which comes in the form of the Earth-based Bioverse corporation and an ambitious plan to relocate many of Dedelphi’s inhabitants into orbit. 

Overseeing the project is human architect Lynn Nussbaumer, who finds that building peace on an alien world may be the most challenging project of her life.

Cover of 'Unanimity' by Alexandra Almeida


By Alexandra Almeida

The first in a six-book series, Unanimity lives by the old motto: "The road to hell is paved with good intentions." The story follows Thomas Astley-Byron, who created a Jungian simulated reality to help humans confront their dark sides and create utopia on Earth. Thomas and his partner, A.I. expert Henry Nowak, are celebrated as gods, and for a time everything seems perfect.

When things start to go downhill, however, Tom (called Shadow by his followers) descends into chaos and heartache. Opposing factions battle for his affection, and not all of them have his best interests at heart. 

Finally, young goddess Estelle Ngoie is appointed to replace him. She seems immune to Shadow's struggles ... and any shred of sentiment. To set things right, Shadow must unravel the strings that pulled him astray — but first, he must regain some semblance of perspective in a changing world that makes it almost impossible.

By Tricia Sullivan

Tricia Sullivan’s high-tech zombie novel introduces the “shine,” a technology that gives people the ability to reprogram their own minds, to get away from the “essential apehood” that we are all doomed to, as one character puts it. 

But when something goes wrong, those who have used the technology become uncontrollably violent, leaving only those who haven’t yet reached puberty intact. 

Trapped within a city gone mad, 14-year-old Xavier needs the drugs that will help keep puberty at bay, while the military has started to suppress the city, block-by-block.

The Long Way to a Small, Angry Planet

By Becky Chambers

Originally self-published, the Wayfarers series by Becky Chambers has become a mainstay of modern science fiction. It begins with The Long Way to a Small, Angry Planet, following Rosemary Harper and her journeys through space with the motley crew of the aging starship, Wayfarer. It's not glamorous, but the ship offers Rosemary a place to sleep and a chance to explore the galaxy. Most importantly, it gives Rosemary a chance to distance herself from her past. 

The Wayfarer is full of strange characters, including the reptilian pilot Sissix and chatty engineers Kizzy and Jenks. When the crew is offered the job of a lifetime, Rosemary and the rest of the team must decide whether a lucrative paycheck is worth risking their lives. If they have any chance of finishing the job and getting out alive, they'll need to rely on one another in a way that Rosemary would really rather not.
