Salvation Day
by Kali Wallace
The ship Houou is a ghost, a silent monument to a plague that wiped out its crew years ago. When a group of desperate activists breaks onto the derelict vessel hoping to expose the truth about the disaster, they find that the ship is far from empty. What follows is a high-pressure scramble for survival as the crew realizes the infection is still active and the ship itself is hiding a massive conspiracy. The pacing is relentless, creating a sense of claustrophobia that makes every corridor feel like a potential grave. You will feel the weight of the airless, metallic environment as the characters turn on each other under the crushing pressure of the unknown. This is a perfect pick for readers who want a fast-moving sci-fi thriller that prioritizes mounting dread and character-driven survival over high-concept world-building.
