His muscles elastic and his mind fragmented, Connor Durham awakens on an unknown beach. In the distance before him is a black tower whose peak rises to meet the clouds. In the water behind him are beings who used to be human, their bodies warping and twisting into horrific new configurations. With nowhere else to turn, Connor runs for the tower.

In the Kadath deep-sea mining facility, Lucas Kane feels haunted. He dreams of lives he never lived and hears whispers from people who don’t exist. During his days, four grey figures vibrate in and out of focus behind him, their words mostly unintelligible mutters. But there’s something else, too, which he sees while both awake and asleep: a sphere, massive, metallic, and beautiful, which awaits him outside Kadath’s walls at the bottom of the ocean.

Separated by dimensions, these two men—and their unfolding stories—are intrinsically linked. As they descend deeper into the dark terrors of the unknown, they will draw inextricably closer together until, at last, both men find themselves trapped in the very depths of otherworldly madness.
