Edition details
Book Summary
A scientist investigates the disappearance of a colleague on the island of Ponape, uncovering a terrifying entity from a hidden world beneath a moonlit pool. As he and his companions delve deeper, they confront a malevolent force that blurs the line between science and the supernatural, leading to a climactic battle for survival.
Dr. Walter Goodwin encounters his friend Dr. David Throckmartin, who is haunted by the loss of his wife and team to a mysterious entity from the Moon Pool on Ponape. Throckmartin vanishes, and Goodwin, joined by aviator Larry O'Keefe and rescued captain Olaf Huldricksson, journeys to the ruins of Nan-Matal. They discover a hidden world called Muria, ruled by the priestess Yolara and her consort Lugur, who worship the Shining One—a radiant, androgynous being created by the ancient Silent Ones. The Shining One feeds on human life force, and Yolara plans to use it to conquer the surface world. Goodwin, Larry, and the handmaiden Lakla ally with the frog-like Akka to resist. After a great battle, the Shining One is defeated, and the Silent Ones' prophecy is fulfilled through sacrifice. Throckmartin and his wife are found dead in each other's arms, and the survivors escape as Muria collapses. The story explores the cost of forbidden knowledge, the duality of ecstasy and horror, and the power of love and loyalty.

Narrative arc
Story tension across the book.
Larry O'Keefe
Larry O'Keefe is the soldier-protagonist whose easy wit and Eton-Harvard polish mask a deep-rooted Irish mysticism he can neither explain nor dismiss. He has heard the banshee twice and seen the green people of Carntogher woods, yet he faces war and danger with a grin, making him both the most modern and most superstitious man in the expedition. His willingness to follow the uncanny where others hesitate makes him the natural partner for Goodwin's scientific inquiry and the pivot on which the story's descent into Muria turns.
Yolara
Yolara rules the Council of Muria alongside Lugur, wielding her beauty and her voice as instruments of control over both her people and the strangers who fall into her realm. She is drawn to the Norseman Olaf with a cold, predatory curiosity, and her laughter at his grief reveals a cruelty that unsettles even her allies. Her authority and her caprice shape the political landscape the protagonists must navigate, and her interest in them is never benign.
Lakla
Lakla moves between the world of the Silent Ones and the human strangers, serving as both guide and beloved, her voice soft with fear and devotion. She brings Larry tidings that he must not fight, a command that wounds his pride but reveals the depth of her care for him. Her connection to the Three and her role in the coming confrontation make her the emotional and spiritual center of the story's middle arc, where love and duty collide.
Rador
Rador is a soldier of the ebon pit caught between obedience to Yolara's Council and a growing bond with the strangers he is ordered to deliver. He kills a fellow guard to save them, then flies the corial through the collapsing Shadow, proving his loyalty is to something beyond rank. His knowledge of Muria's history and his willingness to risk everything for Lakla make him the protagonists' most valuable ally and a man whose divided heart mirrors the story's central conflict.
Olaf Huldricksson
Olaf Huldricksson is a giant of a sailor whose tear-filled eyes and silent endurance mark him as a man hollowed out by loss. He feigns ignorance before Yolara and Lugur, controlling his rage with a discipline that surprises even Goodwin, and he forges a massive mace in preparation for the coming battle. His personal vendetta against the Shining One gives the expedition a raw, human stake in the cosmic struggle, and his fierce joy in the coming fray makes him both tragic and terrifying.
Edith Throckmartin
Edith Throckmartin is the woman whose disappearance with her husband's party first drew Goodwin into the mystery of the Moon Pool, her absence a wound that never quite closes. She exists in the narrative as a haunting presence, her name a caution and a goad, and the symbol of the rosy walls of the Moon Chamber is tied to her fate. Her story is the emotional engine that propels the early investigation and the reason the protagonists cannot turn back from the abyss.
Science vs. the Supernatural
The narrative constantly pits rational scientific explanation against inexplicable, supernatural forces, as characters like Goodwin attempt to analyze the Dweller through physics and chemistry while being confronted with phenomena that defy logic.
Forbidden Knowledge and Pride
The Three created the Shining One out of pride and a desire to unlock cosmic secrets, leading to catastrophic consequences, illustrating the theme that hubris in seeking ultimate knowledge can unleash uncontrollable evil.
Duality of Human Experience
Characters marked by the Shining One exhibit a fusion of ecstasy and horror, joy and despair, suggesting that profound experiences—whether spiritual or traumatic—contain inseparable opposites.
The Power of Light and Energy
Moonlight, colored rays, and the Shining One itself are depicted as tangible forces that can materialize beings, control minds, and drain life, reflecting early 20th-century fascination with unseen energies and radiation.
