Poseidon 1996: Poison of the Deep Sea

When a mutated deep-sea shark left over from the Cold War carrying a rabid flesh-eating virus boards a cut-off ocean liner, those minimally infected gain natural immunity to the zombies. The cowardly captain succumbs to delusions of grandeur and madness, turning the entire vessel into a floating purgatory of human nature.

Stranded in the Atlantic with no hope of rescue, four survivors skilled in ship layout, medicine, combat and communications must devise a full-scale trap to lock hordes of mutated creatures on the open deck. At the same time, they have to stand against the paranoid captain who controls all the ship electrical systems and plans to sacrifice everyone to escape alone. Free of filler subplots, this tight survival thriller delivers nonstop life-or-death confrontations, laying bare humanity good and evil amid desperate circumstances.

The story is fully completed with no unfinished chapters. Centered on a maritime disaster and moral dilemmas, it adheres to consistent rules governing the strength of infected creatures, blending tactical wits with gory, suspenseful combat. It is ideal for a single immersive reading session.
