Gyre Price lied her way onto this deep-cave expedition, desperate for the payday that could launch her search for her mother. She expected dark tunnels, risky terrain, and tight spaces—not Em.
Em is the expedition’s voice in Gyre’s ear, monitoring her every move. With a chilling grip on Gyre’s suit, drugs, and secrets, Em’s control turns the expedition into a nightmare. Supplies go missing, routes shift unexpectedly, and Em’s motives grow increasingly sinister.
Trapped in suffocating darkness, Gyre battles paranoia, the deadly terrain, and a monstrous underground predator. But to survive, she must confront not only the terrors around her but the ones buried in her own mind. And all the while, she feels it: something—or someone—is following her.
