What if the experiment designed to reveal the cosmos' truths ripped open a door that was never meant to be opened?

Once a leading physicist at CERN, Revalina Clark saw the first tears and warned them; they pressed on without her, and now a lost soul, she watches with creeping fear as seams widen, impossible entities leak through, and memory frays.

Science gone wrong becomes an accelerating collapse: seams widen, panic spreads, rituals replace reason, and the city tips toward an end?of?the?world nightmare. Revalina must confront the horror she set in motion and fight to hold on to her identity as reality bleeds away.

If you were entranced by the labyrinthine dread of House of Leaves, the ecological unease of Annihilation, or the haunting humanity of Station Eleven, then Penumbra: The Unmaking of Earth is for you. This is a story of destruction, fear, and chaos - laced with moments of terrible beauty and a glimmer of hope in the most unexpected places.
