The Moon Maid

In Short

Edgar Rice Burroughs’s The Moon Maid is an episodic planetary romance and multi-generational science fiction epic. Spanning centuries, it follows three successive generations of the Julian bloodline: from an initial space expedition to the hollow, inhabited interior of the Moon, to a brutal alien invasion of Earth, and finally to a post-apocalyptic frontier war for liberation. Combining wild pulp adventure, monstrous creatures, and political allegory, the novel has endured as a classic example of early twentieth-century speculative fiction that explores the cyclical nature of human conflict, freedom, and civilization’s fragile persistence against barbarism.

The Story

The narrative opens in 1967 as a framed memory told aboard an airship. Captain Julian 5th commands The Barsoom, the first vessel traveling to Mars. During the flight, a treacherous officer named Orthis sabotages the engines, forcing the ship off course to make an emergency landing inside the hollow interior of the Moon, known to its inhabitants as Va-nah.

Exploring this hidden, light-filled lunar realm, Julian and his crew discover an ecosystem inhabited by both quadrupedal humanoids called Va-gas and human-like beings called U-ga. Julian meets Nah-ee-lah, the Princess of Laythe, whom he calls the Moon Maid. Julian and Orthis become entangled in the bloody local rivalries between the civilized Laytheans and the oppressive, savage Kalkars, a mongrel race seeking total rule. When internal rebellion and fire destroy the subterranean city of Laythe, Orthis aligns himself with the Kalkars, providing them with advanced weaponry and knowledge of space travel, while Julian escapes with Nah-ee-lah back to Earth.

Decades later, the bitter seeds sown inside the Moon bear destructive fruit. Led by Orthis's technology and guidance, the Kalkars launch an armada to invade Earth. The planet falls to the invaders, entering a dark age of total submission. By the era of Julian 8th, Earth is reduced to a feudal agrarian society governed by ruthless Kalkar overlords who suppress technology, outlaw liberty, and forbid the display of the American flag. Julian 8th leads a heroic underground uprising, fighting to free his family and fellow Yanks from forced labor in the mines, though the war against the Kalkars remains unfinished.

Centuries further into the future, Julian 20th—known as The Red Hawk—leads the nomadic American tribes in a final, centuries-long campaign to drive the remaining Kalkar invaders to the coast. Riding horseback across a wild, ruined continent, Red Hawk encounters remaining pockets of brutal monsters and hostile warlords, including the giant Raban. Defeating his enemies through combat, Red Hawk eventually captures Bethelda, the daughter of the Kalkar leader Or-tis 16th. Rather than continuing an endless cycle of blood vengeance, Red Hawk and Or-tis negotiate terms, uniting their people in marriage to establish a lasting peace and restore civilization to the continent.

• Orthis: A brilliant but bitter, insubordinate officer on The Barsoom. Consumed by hatred for Julian, he betrays humanity by providing the barbaric Kalkars with advanced weapons and technological knowledge.

In Its Own Voice

"It is The Flag, my son," said Father to me. "It is Old Glory—the flag of your fathers—the flag that made the world a decent place to live in."

Julian 8th's father reminds him of the sacred historical bond represented by their hidden family heirloom under total Kalkar tyranny.

"There can be no friendship between a Julian and an Or-tis," I replied, coldly.

Julian 20th reasserts the centuries-old feud when brought face-to-face with the leader of his bitter ancestral enemies.

"The safer way," he said, "is to follow the trail that winds along the summit of the hills, back toward the camp of the Kalkars—a great trail that was built in the time of Mik-do..."

A native guide warns The Red Hawk of the perilous paths through the wilderness surrounding the stronghold of the giant Raban.

What It's Really About

Beneath its pulp adventure exterior, the book examines the cyclical nature of human history and the fragility of civilization. It presents a grim warnings about political extremism, tyranny, and societal decay, contrasting the spirit of individual freedom with the destructive force of envious, authoritarian rule. Through the generations-long feud between the Julian and Orthis lines, the story argues that liberty must be continually fought for and defended, yet true reconstruction can only occur when hatred is set aside in favor of peace and unity.

Why Read It Today

Fans of early twentieth-century speculative fiction, space opera, and planetary romance will find much to admire in this grandly imaginative tale. The novel moves at a breathless pace, shifting smoothly from high-tech space navigation to subterranean alien intrigue and post-apocalyptic horse-cavalry warfare. Its vision of a hollow Moon and a ruined, feudal North America offers a vivid showcase of speculative world-building. Readers should be prepared for the episodic structure and the dramatic shifts in setting between its three distinct sections, as well as period-typical black-and-white morality and sensationalist melodrama. Yet despite these dated stylistic elements, the story's core drive—a century-spanning struggle for freedom—remains an engaging and satisfying classic adventure.
