Hundreds of years in the future, after the collapse of the Western world, young Menelaus Illation Montrose grows up in what was once Texas as a gunslinging duelist for hire. But Montrose is also a mathematical genius—and a romantic who dreams of a future in which humanity rises from the ashes to take its place among the stars. The chance to help usher in that future comes when Montrose is recruited for a manned interstellar mission to investigate an artifact of alien origin. Known as the Monument, the artifact is inscribed with data so complex, only a posthuman mind can decipher it. So Montrose does the unthinkable: he injects himself with a dangerous biochemical drug designed to boost his already formidable intellect to superhuman intelligence. It drives him mad. Nearly two centuries later, his sanity restored, Montrose is awakened from cryo-suspension with no memory of his posthuman actions, to find Earth transformed in strange and disturbing ways, and learns that the Monument still carries a secret he must decode—one that will define humanity’s true future in the universe.

Continuing from Count to a Trillion, Menelaus Illation Montrose―Texas gunslinger, idealist, and posthuman genius―has gone into cryo-suspension following the discovery that, in 8,000 years, a powerful alien intelligence will reach Earth to assess humanity's value as slaves. Montrose intends to be alive to meet that threat, but he is awakened repeatedly throughout the centuries to confront the woes of an ever-changing and violent world, witnessing millennia of change compressed into a few years of subjective time. The result is a breathtaking vision of future history like nothing before sweeping, tumultuous, and evermore alien, as Montrose's immortal enemies and former shipmates from the starship Hermetic harness the forces of evolution and social engineering to continuously reshape the Earth in their image, seeking to create a version of man the approaching slavers will find worthy.

The year is 10,515 AD. The Hyades Armada, traveling at near lightspeed, will reach Earth in just four centuries to assess humanity's value as slaves. For the last 8,000 years, two opposing factions have labored to meet the alien threat in very different ways. One of them is Ximen del Azarchel, immortal leader of the mutineers from the starship Hermetic and self-appointed Master of the World, who has allowed his followers to tamper continuously with the evolutionary destiny of Man, creating one bizarre race after another in an apparent search for a species the Hyades will find worthy of conquest. The other is Menelaus Montrose, the posthuman Judge of Ages, whose cryonic Tombs beneath the surface of Earth have preserved survivors from each epoch created by the Hermeticists. Montrose intends to thwart the alien invaders any way he can, and to remain alive long enough to be reunited with his bride Rania, who is on a seventy-millennia journey to confront the Hyades' masters, tens of thousands of light-years away. Now, with the countdown to the Hyades' arrival nearing its end, del Azarchel and Montrose square off for what is to be their final showdown for the fate of Earth, a battle of gunfire and cliometric calculus; powered armor and posthuman intelligence.

The epic and mind-blowing finale to this visionary space opera series surpasses all expectation: Menelaus Montrose, having forged an uneasy alliance with his immortal adversary, Ximen del Azarchel, maps a future on a scale beyond anything previously imagined. No longer concerned with the course of history across mere millennia, Montrose and del Azarchel have become the architects of aeons, bringing forth minds the size of planets as they steer the bizarre intellectual descendants of an extinct humanity. Ever driving their labors and their enmity is the hope of reunion with their shared lost love, the posthuman Rania, whose eventual return is by no means assured, but who may unravel everything these eternal rivals have sought to achieve. John C. Wright's The Architect of Aeons is the latest in his millennia spanning space opera.

Innumerable ages have passed since Menelaus Montrose last beheld his loved Rania, who departed the Milky Way long ago to plead for humanity before the authority whose inhuman laws govern the Orion Arm. Man has altered himself by forced evolution and created godlike machines, larger than worlds, which now determine human destiny. But a new star burns in the skies of Earth: it is the celestial vessel of Rania, returning, Montrose hopes, with the cliometric equations promising equality, peace and liberation. In the barren wastes of Torment, the world that is home to the last and most distant human colony, Montrose and his equally immortal rival, Del Azarchel, meet again, this time in a common cause to discover the fate of Rania, of humanity, and of the galaxy itself. The alien monstrosities of Ain at long last are revealed, their hidden past laid bare, along with the reason for their brutal treatment of humanity and all the species seeded throughout the Orion Arm. And they have still one more secret that could upend everything Montrose has fought for and lived so long to achieve.

The spectacular conclusion to the thought-provoking hard SF Eschaton Sequence, exploring future history and human evolution. An epic space opera finale worthy of the scope and wonder of The Eschaton Sequence: Menelaus Montrose is locked in a final battle of wits, bullets, and posthuman intelligence with Ximen del Azarchel for the fate of humanity in the far future. The alien monstrosities of Ain at long last are revealed, their hidden past laid bare, along with the reason for their brutal treatment of Man and all the species seeded throughout the galaxy. And they have still one more secret that could upend everything Montrose has fought for and lived so long to achieve.
