Beneath the Alps, the dead are still awake.
Cassian Vale wakes in agony with no memory of how he was captured, only the horrifying certainty that something inside his body has been activated. Hunted through the city by machines wearing stolen human memories, Cassian escapes with one goal: find the truth before the thing inside him finishes waking up.
But the truth is buried beneath the Alps.
There, hidden under ice and stone, lies the Underlayer - a vast experimental system built to preserve human consciousness after death. Millions of fractured minds are trapped inside it, whispering, waiting, and reaching for the one person designed to hold them all.
Cassian was never just a survivor.
He was the anchor.
As his dead lover, his lost twin brother, and the mother who betrayed him pull him deeper into the machine, Cassian must decide whether to destroy the Underlayer or become the only thing powerful enough to control it.
Because some doors should never be opened.
And some memories refuse to stay dead.
The Underlayer is a dark sci-fi horror thriller packed with body horror, buried technology, fractured consciousness, terrifying secrets, and a cinematic battle between memory, grief, and survival.
