Best Sci-Fi Books of 2025: Must-Reads from New Scientist

A Diverse Year for Sci-Fi Lovers: 2025’s sci-fi scene is richer than ever. New Scientist highlights a mix of bold new novels, debut authors, and imaginative re-imaginings, offering something for fans of space opera, climate fiction, dystopias and far-future speculation.

Standout Releases: Fresh Voices & Bold Visions: Books like Circular Motion by Alex Foster challenge readers with a dystopian future where Earth’s rotation accelerates, a clever, haunting premise praised by New Scientist for its ambition and emotional depth. Similarly, The Shattering Peace by John Scalzi returns to his beloved space-opera universe, delivering high-stakes interstellar conflict with wit and optimism.

Early-Year Highlights Worth Watching: The magazine’s 2025 spotlight includes intriguing upcoming titles such as Death of the Author by Nnedi Okorafor, All the Water in the World by Eiren Caffall and We Lived on the Horizon by Erika Swyler among others, signalling a strong start to the year and showing the breadth of themes sci-fi has to offer.

Wide Range of Themes: From Drowned Worlds to Generation Ships
From eco-thrillers and climate collapse to generational starships and futuristic AI, 2025’s picks reflect current anxieties and hopes. Expect haunting alternative histories, speculative dystopias, interstellar adventures, and deep explorations of identity and survival.

Returning Icons & Prolific Authors: Well-known authors re-emerge with major works, their stories acting as anchors for fans even amid fresh voices. Classic space opera, sweeping world-building, and thought-provoking themes keep the genre grounded yet expanding.

Why These Books Stand Out (and What to Know Before You Dive In)
These selections stand out for:

• Bold, imaginative premises that push genre boundaries.

• Emotional depth and philosophical themes, often exploring humanity’s future, climate, memory, identity.

• Diversity: in voices, settings, and speculative concerns.

But be ready: some novels are dense, complex, and heavy on ideas, rewarding for readers who enjoy depth and challenge.

Your 2025 Sci-Fi Reading List Starter Pack: Whether you’re new to sci-fi or a longtime fan, start with Circular Motion or The Shattering Peace for accessible yet rich sci-fi. For something fresh and original, look out for early-year picks like Death of the Author or We Lived on the Horizon. These titles show why 2025 might be a landmark year for speculative fiction.
