Fragmented stories from the shooting of Khalil Berro's Calidum Innatum, kilometres deep within a decommissioned coal mine. Filmed over days of living and sleeping underground, the film will never see the light of day; its film stills existing only within this book.

In search of life's vital heat within the rock, and drawn by a deep pull toward black gold's transformative powers, the book holds explosions and haunting stares alongside excerpts from As Sunshine Turns to Stone (2024).
