Two hundred meters down, in a pressurized steel tomb, your voice isn't the only thing the helium distorts.
Deepwater saturation diver Claire Nellis has spent her career in the crushing dark of the North Sea. But this rotation is different. The death of a crewmate on the previous shift was written off as a tragic accident-a panicked diver, a fouled line. The official report is closed.
But Claire finds the hose. The cut is clean. Surgical.
Trapped in the claustrophobic habitat of the Borealis with three other survivors, Claire realizes the killer is still among them. In the suffocating heat and the mind-altering pressure, every breath is a struggle. And with the heliox atmosphere turning every voice into a cartoonish squeak, you can't tell a threat from a joke, or a scream from a laugh.
When a mysterious storm severs their lifeline to the surface, the real nightmare begins. Stranded, freezing, and running out of air, Claire must uncover the truth before the ocean does the killer's work for them. But in a world where your own senses can't be trusted, the deepest terror isn't the abyss outside-it's the monster inside the room.
In the crushing darkness, everyone sounds guilty
