April 2026 offers a rich selection of science fiction, ranging from thrilling space adventures to haunting explorations of AI and the human condition. This month’s releases cater to diverse tastes, with stories set on Mars, in deep space, and within the emerging landscapes of technological horror. Here’s a breakdown of the standout titles.

Martian Escapes and Space Thrillers

Mars One by Charlotte Robinson kicks off the month with a high-stakes near-future thriller. The novel intertwines a one-way mission to Mars with the mysterious disappearance of a programmer in Hong Kong. The narrative promises suspense, echoing the tension of Andy Weir’s The Martian blended with the espionage of Terry Hayes’s I Am Pilgrim.

For those craving cosmic horror, Dead Silence by S. A. Barnes delivers. The story follows a crew investigating a derelict space-liner lost for two decades. What they find aboard – whispers, blood-scrawled warnings – suggests something far more terrifying than simple abandonment. This is classic space horror at its finest.

Speculative Fiction and Award-Winning Stories

Rabbit Test and Other Stories by Samantha Mills presents a diverse collection of speculative fiction. The anthology spans sci-fi, fantasy, and literary themes, including tales of first contact, time-bending adventures, and the emergence of new consciousnesses. The inclusion of Mills’s award-winning story, “Rabbit Test,” guarantees a high-quality read.

Epic Series and Dark Futures

Fans of grand space operas should look to The Faith of Beasts by James S. A. Corey, the second installment in the Captive’s War series (from the creators of The Expanse ). This installment continues humanity’s desperate fight against the monstrous Carryx empire, following a human captive caught between warring factions.

Metro 2035 by Dmitry Glukhovsky brings the conclusion to the Metro trilogy. Twenty years after a global war decimated civilization, survivors cling to life in Moscow’s subway system. The novel follows Artyom’s relentless search for a way back to the surface, a desperate hope in a shattered world.

Emerging Technologies and Existential Questions

No Ghosts by Max Lury explores the haunting potential of AI-generated videos, where fragments of the dead linger in digital spaces. The story follows two characters searching for a missing friend, delving into the unsettling intersection of technology and loss. This novel promises a unique take on modern haunting.

The Body Builders by Albertine Clarke examines loneliness through a sci-fi lens. The protagonist, Ada, finds herself increasingly isolated until she’s drawn into an artificial environment designed solely for her existence. The novel questions the nature of reality and the search for connection in an age of technological detachment.

Bizarre Experiments and Ancient Threats

Paradox by Douglas Preston and Aletheia Preston returns to the world of resurrected prehistoric creatures with a twist. This sequel introduces an alien artifact, a fanatical cult, and Neanderthals who resent humanity’s dominance. The novel blends action, conspiracy, and genetic horror for a fast-paced read.

Sleeper Straddle edited by George R. R. Martin dives into the chaotic Wild Cards universe, where an alien virus causes unpredictable mutations. The collection features stories by authors like Cherie Priest and Walter Jon Williams, following characters split into multiple incarnations in a world forever altered by biological chaos.

Unconventional Narratives

Event Horizon by Balsam Karam, translated by Saskia Vogel, presents a stark rebellion against a tyrannical government. The novel follows Milde, a 17-year-old facing execution or forced participation in an experimental mission into a black hole. This is a brutal and philosophical exploration of survival and sacrifice.

The Many by Sylvain Neuvel offers a mind-bending first-contact story. Five residents of a small Michigan town discover that their consciousnesses are merging with something larger and stranger. The narrative explores themes of collective identity and the unknowable vastness of the universe.
