In Salvation Day, did you enjoy ...

... a locked-ship mystery with a corporate cover-up and grisly aftermath?

Dead Silence by S.A. Barnes

If the hijacking of Jaya to reach the derelict House of Wisdom—and the slow unspooling of what the authorities hid there—hooked you, you’ll love how Claire Kovalik’s salvage team boards the luxury liner Aurora and uncovers passenger recordings, staged scenes, and corporate fingerprints on a massacre. Like Zahra’s crew, Claire’s people are trapped in tight corridors with conflicting agendas as a buried truth turns the ship itself into a crime scene. Dead Silence keeps tightening the screws while each new clue makes survival more doubtful.

... claustrophobic, single-location survival with a fraught two-person dynamic?

The Luminous Dead by Caitlin Starling

If the sealed compartments, quarantine doors, and tense back-and-forth between Zahra and Jaya made your pulse spike, The Luminous Dead channels that same pressure-cooker intensity. Caver Gyre Price descends alone into a lethal cave system while her only lifeline is Em, a remote handler who lies as often as she helps. As in the House of Wisdom’s airless passages, every meter forward feels like a gamble, and the mission’s real purpose only emerges when it’s almost too late to turn back.

... morally gray protagonists pursuing a risky mission they believe justifies the harm?

Goldilocks by Laura Lam

If you were compelled by Zahra’s willingness to kidnap Jaya and breach the House of Wisdom in service of a cause, Goldilocks puts you with a crew of women who steal a starship to save humanity from a broken Earth. Naomi Lovelace backs Captain Valerie Black’s audacious theft, only to confront secrets, ethical compromises, and consequences that mirror the uneasy trade-offs in Salvation Day. You’ll recognize that same knotty question: how far can you go—and who must you hurt—to achieve a ‘greater good’?

... high-stakes survival when a mission enters an unknowable structure that fights back?

The Last Astronaut by David Wellington

If the scramble to stay alive once the pathogen and systems aboard the House of Wisdom began turning on Zahra’s crew grabbed you, The Last Astronaut sends Sally Jansen into an alien object where corridors shift, hazards multiply, and the environment itself becomes a predator. As with the House of Wisdom’s deadly surprises, each discovery raises the body count and forces ugly choices, keeping the focus on nerve, teamwork under strain, and bare-knuckle survival.

... relentless, corridor-to-corridor science-fiction horror that never lets up?

Hull Zero Three by Greg Bear

If you tore through the rapid escalations—from the hijacking to the first infections to the final revelations—Hull Zero Three hits that same throttle. An amnesiac wakes into a failing starship where frozen crewmates, hostile biologies, and twisting passages demand immediate, brutal decisions. Like Zahra and Jaya racing through the House of Wisdom’s decks, the protagonist is always one step ahead of the next lethal surprise, with answers arriving only as fast as the danger.
