Newly published by Palmetto Publishing, Operation Agartha weaves three darkly imaginative tales of war, hidden civilizations, and spiritual conflict into a single debut collection.

CHARLESTON, S.C., Sept. 15, 2026 /PRNewswire/ — Palmetto Publishing has released Operation Agartha, a debut speculative fiction collection blending military history, mythology, and spiritual conflict into three distinct narratives. The book explores hidden civilizations, ancient legend, and the hidden forces that shape war, and is now available through major online retailers, including Amazon.com and BarnesandNoble.com.

The collection opens with “Operation Agartha,” in which exorcist Dr. Shipwright is pulled from the rain-soaked streets of Portland into a supernatural conflict rooted in declassified post-World War II military history, after a joint Navy and Marine operation uncovers the lost underground civilization of Agartha. In “The King Maker,” civilian Devon Price discovers that military weapons software built to hunt enemies can be repurposed to sell art and solve urban crime. The closing tale, “The Emerald Cup,” follows a combat engineer at the Battle of Okinawa who steps into a vacant Japanese bunker and encounters something far more unsettling than the dead.

Across all three stories, characters face threats that blur the line between the physical and spiritual, including a centuries-old force from Tartarus that pushes humanity to ally with the beings of Agartha and form a new military order called the Leonem.

“I wanted to write stories that cover topics like inner space and a familiar darkness that is unnerving without being too violent,” said Quigley. “The characters are tough and inquisitive, and the worlds they move through are grounded in real history and old legends passed down for generations.”

Operation Agartha is positioned for fans of military science fiction and speculative adventure, particularly readers of Jeremy Robinson’s hollow earth thrillers and James Rollins’ action-driven historical fiction. Themes of wartime camaraderie, mentorship, and the toll of prolonged conflict will appeal to veterans, history enthusiasts, and readers drawn to mythology-infused military fiction.

Operation Agartha is available for purchase online at Amazon.com and BarnesandNoble.com.
