The land was the first to fall. When the Red Vein virus swept across the continents, it didn't just kill—it rewrote the genetic code of everything it touched, turning humanity into a twitching, hive-minded nightmare. For three years, the only sanctuary was the sea. The high salinity of the deep ocean acted as a natural barrier, keeping the virus at bay while the last remnants of civilization fled to a makeshift "City of Chains"—a massive flotilla of lashed-together ships and oil rigs.
But the salt pact has been broken.
Mara, a hardened lookout on the northernmost derrick, is the first to see the impossible: the virus has mutated. It has submerged, infecting the leviathans of the deep and turning the ocean itself into a hunting ground. As the Red Vein begins to climb the anchor chains of the last human stronghold, Mara must team up with Elias, a young scavenger from a battered trawler, to protect a secret hidden in the Arctic ice.
The "Source" is waking up.
Driven by a haunting, subsonic "Song" that only the infected can hear, a massive biological entity is moving toward the Svalbard Seed Vault. If it reaches the vault, the virus will rewrite the DNA of every plant on Earth, ensuring humanity has no world to return to. With their home sinking and their friends turning, Mara and Elias must navigate a frozen graveyard to bury the virus before the Crimson Aurora signals the end of everything.
In a world where nothing survives, the only hope is to freeze the future.
