A collider opens a gateway. The damned are waiting.

When a physics experiment rips open reality, physicist Emily Loughty vanishes—and in her place appears a long-dead killer. To save her, ex-soldier John Camp crosses into Down, a parallel world of eternal war.

Here, the dead cannot die. Kings and tyrants—Henry VIII, Himmler, Borgia, Robespierre—rule fractured kingdoms, waging endless battles for power. Those who defy them are cast into rotting rooms, condemned to decay forever.

As John fights his way through betrayal and shifting alliances, Emily is hunted for her knowledge by rulers who would weaponize science itself. To survive, they must find each other before the portal closes.

Down: Pinhole launches Glenn Cooper’s epic saga—Inferno reimagined as Game of Thrones, where science tears open Hell and history’s monsters fight to rule it.
