The best new science-fiction books of April 2026

A collection of stories set in George R. R. Martin's universe and a novel from author James S. A. Corey are among the science-fiction books we're looking forward to this month I am currently reading the science-fiction classic by Kim Stanley Robinson with the New Scientist Book Club (it's our April read). It's fantastic, so any other trips to the Red Planet are very welcome from my perspective, and I'm looking forward to Charlotte Robinson's thriller . Elsewhere in this month's science fiction, there's horror in space from S. A. Barnes, some resurrected Neanderthals from Douglas Preston and his daughter Aletheia Preston, and ghosts in AI-generated videos from Max Lury. Something for all tastes, I'd say. This near-future space-thriller follows a one-way mission to Mars, as well as the disappearance of a programmer in Hong Kong, who leaves nothing behind but a cryptic warning. As the Argo spaceship heads towards Mars, the crew realise they are being sabotaged.
