The best sci-fi romance novels that will make you think

I adored this book. I fell in love with the male main character, Commander Graham Gore, a Victorian explorer brought into a near-future London via a time travel machine. The author deftly handles how Graham might experience the modern world. His relationship with the narrator is complex and fascinating, and gets very sexy!

Bradley explores themes of colonialism, climate change, and identity within a thrilling time travel plot and swoony romance. I think her style of sci-fi romance—exploring big ideas within interesting, exciting stories with characters you root for—could be the next big thing in publishing. I can’t wait to see what she writes next.

This book inspired my love of sci-fi romance. I adore the characters and the deceptively simple premise. Cordelia Naismith is a badass survey captain stranded on a wild planet with only her enemy, Aral Vorkosigan, known as The Butcher of Komarr, for company.

As they trek through the wilderness, Cordelia gets to know Aral and realizes her assumptions about him are all wrong. Originally published in 1986, this book launches the Vorkosigan Saga—my favorite sci-fi series. What I love about this book is how Bujold takes the time to let Cordelia and Aral get to know each other as people and bond on a deep emotional and intellectual level. They may be on opposite sides of a war, but they recognize the humanity in each other.

This book feels like a warm hug. Disreputable playboy Prince Kiem must marry his cousin’s windower, Jainan, to keep the interplanetary peace. I loved watching Kiem and Jainan’s relationship unfold and was SO HAPPY when they finally admitted their feelings to one another. And I loved seeing a variation of my favorite trope—there was only one tent—that played an important role in getting them together.

Maxwell doesn’t shy away from dealing with heavy topics like domestic violence and imperialism, while keeping the tone fun. From the podcast My Word as Vorkosigan, I learned that Everina Maxwell is a fellow Lois McMaster Bujold superfan, and I wasn’t surprised! Like Bujold, Maxwell uses a sci-fi setting to explore grounded relationships with snappy dialogue and exciting action. 

I loved the fun enemies-to-lovers-back-to-enemies romance between “memory merchant” Liv and rookie foreman Adrian, set against a disturbingly realistic dystopia. In the world of the Metro, people have traded security for real experiences.

They’ve never tasted real food, spent time in nature, or seen the stars. Instead, they are constantly grinding to keep up their productivity scores. I was drawn to the critique of the gig economy and the use of technology to maximize efficiency over humanity. Dystopian sci-fi is back, baby!

This book is unhinged in the best way. I love Gideon’s unique voice. Around her is a deadly-serious necromancer murder mystery with interplanetary stakes, and she cares more about cracking dirty jokes and finally eating some warm food. Her relationship with her arch-nemesis/only friend Harrow leaps off the page.

I love the scene where they get into a pool so Harrow can finally confess to Gideon her darkest secret—so hot and so disturbing all at the same time. While this book isn’t technically a romance and the genre feels more like a horror fantasy set in space, I couldn’t resist putting it on the list. As Gideon says to Harrow, “One flesh, one end, bitch.”
