Somewhere far off the California coast in the Pacific Ocean a thousand meters down lies a Top Secret U.S. Government manned research outpost called Sea Station Umbra. Thought to be a Fukushima radiation monitoring station, its real purpose remains a mystery. A hundred people on Earth know of its existence but only thirty seven know what it is and why it's there. As things in the station begin to go horribly awry, a black ops mission Operation Deep Force is dispatched to investigate and intervene but encounters a situation far beyond their wildest imaginations.

A deep-sea thriller-mystery filled with suspense, chills, and heart-stopping action, it takes you back to those days of 2001, the Abyss, and Sphere and leaves you cold, deep and gasping for more.
