They saved the world in wartime. Now their daughter has vanished into something far worse.

When a child disappears through a secret tunnel beneath a hero's mansion, Detective Skip Gibson expects a ransom demand or a tragic accident. Instead, he uncovers occult rituals, demonic pacts, and conspiracies stretching back to blood-soaked ceremonies in 1940s Mexico. The city's most celebrated champions built their power on sacrifices that would make ordinary criminals look merciful.

As mysterious technology begins transforming citizens into mechanical horrors, the investigation spirals beyond normal comprehension. Ancient vessels of unknown origin release contamination across Empire City while supernatural forces manifest through a possessed oracle speaking of apocalypse. Government cover-ups collide with cosmic entities, and every answer Gibson uncovers reveals that the heroes he trusted were never what they seemed.

With humanity caught between demonic bargains and an invasion from the past, the line between savior and monster dissolves completely. Retired legends harbor secrets worth killing to protect, Cults operate in plain sight, and the truth about wartime heroics threatens to tear reality itself apart. In 1950s America, the greatest threat isn't communism or foreign enemies but the corruption festering behind patriotic masks.

Can anyone survive when the protectors become the predators?
