The day humanity woke up, the world had already been transported... and they opened their eyes inside the stomach of a Abyssal Leviathan. This living nightmare is their new home-they only shelter in the crushing deep. Every surge of seawater flooding through its stomach walls brings unpredictable resources... and unspeakable threats hiding in the dark. Here, breathing is a privilege, food is won through combat, and the monthly Trials push survivors to the brink of madness. While everyone else struggles just to stay alive, Damian has a secret advantage: he can hear the Leviathan's heartbeat... and the voice within it. As he leads the desperate exploration of the endless world, one question haunts them all: What waits beyond the deep sea ? The answer: A deeper, darker ocean-and a new world opening its jaws to swallow us whole.
