Nine Days at Depth
A Saturation Diver's Survival

About this book:

At 190 meters beneath the North Sea, the only thing thinner than the margin for error is the helium-laced air in Chamber 3. Saturation divers Sean Vance and Toby Miller are nine days into a pressure-cooker existence where a single gauge fluctuation means death, the storm topside has severed their lifeline to the surface, and the generators have just died—plunging them into freezing, lightless silence with a finite supply of breathable gas and no way to call for help. Trapped in a steel tube where the physics of decompression make escape impossible, they have seven days of agonizing ascent between them and the surface, assuming the ship holds together that long.

Sean has spent fifteen years reading the pulse of vessels and the moods of the deep, but the *MV Sovereign* is singing a new and terrible song: thrusters hunting, generators tripping, the dynamic positioning system failing against a sea that refuses to be modeled. Toby masks razor-sharp instincts behind gallows humor, but even he can't joke away the dropping temperature, the rising CO2, or the knowledge that their umbilical to the bell—and the seabed job that pays their mortgage—is a thread the storm is determined to cut. With communications dead and the surface crew fighting their own battle for survival, the divers are left to calculate how long they can last on battery-powered scrubbers and body heat before the cold or the bad gas claims them first.

*Nine Days at Depth* is a masterclass in claustrophobic suspense, written with the brutal authenticity of someone who knows the taste of heliox and the weight of nineteen atmospheres. From the visceral terror of a blow-down to the quiet horror of watching a pressure gauge drift in the dark, this is survival fiction at its most technically precise and humanly raw—a relentless descent into the mechanics of disaster and the psychology of men who work where the ocean does not forgive mistakes.
