After a lifelong love affair with science fiction, it’s safe to say it’s one of my favorite — and most read — genres, right alongside fantasy. Whatever expertise that lends a person, I certainly have it. So when I tell you you need to read these ten sapphic sci-fi novels because they’re equal parts inventive and captivating, I mean it. They all feature sapphic protagonists, but they are also innovative additions to the sci-fi canon, full of world-building and stories that pay homage to classic science fiction tropes while breaking their own ground.
SFF as a whole is full of beautiful, queernorm worlds where queer characters can exist in a space in which their sexuality isn’t politicized or ostracized. We’ve talked about a lot of queer SFF here on Book Riot, from the best of queer fantasy to sapphic dark fantasy. Queer SFF romance abounds, and we’ve even covered queer SFF for the genre-shy. That’s a lot of great recommendations, but it does skip over one specific subgenre: sapphic sci-fi. That’s where this list comes in, because I’d say it’s high time sapphic sci-fi gets its moment in the sun. So whether your interest is in reading more queer sci-fi or expanding your knowledge of excellent new science fiction, these sapphic sci-fi books need to make their way onto your shelves.
