10 Brilliant Science Fiction Novels to Read This Spring (2025)

From epic space sagas to speculative Earthbound thrillers, these are the sci-fi books worth your attention this season.

Science fiction has always been the genre of what if. It lets us test the limits of human imagination—across galaxies, timelines, and futures yet to be written. Whether you're drawn to cerebral space operas, unsettling dystopias, or mind-bending near-future scenarios, the stories collected here are a testament to the power of speculative fiction to illuminate, challenge, and transport. Some have just arrived, others have been quietly gathering acclaim, and a few are still shimmering on the edge of release.

The Terraformers 

Annalee Newitz

Centuries in the future, a team of planetary designers uncover corporate secrets buried beneath the soil of a terraformed planet. With ecological rebellion, AI consciousness, and late-stage capitalism all in the mix, this is big-idea sci-fi with a deeply human pulse.
