Ex-soldier Mark Harrigan can't shake the visions that followed him home from a firefight in Mexico, where his unit stumbled on a hidden Mi-Go excavation and barely escaped with their lives. In Arkham, psychologist Carolyn Fern and reformed cultist Diana Stanley are drawn into Harrigan's case as they uncover a Silver Twilight Lodge plot to open the way for worse things than what he saw underground.
