Shards of Earth

The first book of the Final Architecture trilogy is set in a far-future galaxy where humanity has scattered across the stars in a diaspora known as the Polyaspora, following the destruction of Earth by an Architect, a moon-sized alien entity that reshapes inhabited worlds into enormous, intricate sculptures. For nearly 80 years, the Architects targeted one human colony after another. Humanity's only effective countermeasure was the Intermediary Program, which surgically altered human brains to allow a select few to navigate unspace, a dimension underlying real space used for faster-than-light travel, and to make mental contact with the Architects. At the Battle of Berlenhof, the administrative heart of the Colonies, an Intermediary named Idris Telemmier helped the defending fleet destroy an Architect for the first time. Six years later, at Far Lux, Idris and two other Intermediaries reached an Architect's consciousness, making it aware that humans existed as thinking beings. The Architects simply vanished, ending the war.

Forty years have passed. Idris, who has neither slept nor aged since the Program altered his brain, works as a navigator aboard the Vulture God, a salvage vessel captained by Rollo Rostand. His crewmates include Kris Almier, his lawyer and business partner; Olli, a remote specialist born with severe limb differences who operates a massive workframe called the Scorpion; Kittering, a member of the crab-like Hannilambra species who manages the crew's finances; and Medvig, a Hiver, a composite intelligence made up of many insect-like cyborg components inhabiting a metal frame.

The Parthenon, an independent human faction of genetically engineered women originally created as humanity's military elite, dispatches Myrmidon Executor Solace to recruit Idris. Solace fought beside Idris at Berlenhof and shared a bond forged in combat. Acting on intelligence from Ash, a singular alien known as the Harbinger who warned Earth before its destruction, Solace tracks Idris to the world of Roshu. There, a Magdan nobleman named Boyarin Piter Uskaro attempts to seize Idris under the Liaison Board's system of leash contracts, which effectively enslaves modern Intermediaries. Kris secures Idris's release by proving he is a free wartime Int who predates the leash system. Solace helps the crew escape Uskaro's enforcers and signs on as a crewmember, concealing her true mission.

Aboard ship, Solace reveals her purpose, but Idris refuses, insisting he will not be owned by any government. The crew proceeds to their next job: retrieving the Oumaru, a missing freighter, near Huei-Cavor, a colony world defecting from Hugh, the Council of Human Interests that governs the Colonies, to the Essiel Hegemony, an alien empire whose rulers can protect planets from Architects using Originator relics, artifacts left behind by a mysterious vanished civilization. Idris navigates into the deep void and finds the Oumaru reshaped into the unmistakable floral sculpture of an Architect attack, the first such evidence in 40 years.

The crew returns the wreck covertly to Lung-Crow Orbital. Hierograve Sathiel, a senior Hegemonic cultist, invites the crew to help him display the wreck publicly to demonstrate the renewed Architect threat. During the attempt to liberate their impounded ship, armed hijackers led by Mesmon, a Tothiat, a human grafted with a symbiotic alien creature that grants extraordinary regenerative abilities, storm the docking bay. In the ensuing firefight, two crewmates are killed, and the hijackers escape with both the Vulture God and the Oumaru.

Kris discovers the hijackers work for the Broken Harvest Society, a Hegemonic criminal cartel, and traces their destination to Tarekuma, a lawless world. Solace requisitions a Partheni ship, the Dark Joan, so Idris can navigate through the deep void and arrive ahead of the hijackers. On Tarekuma, Kris arranges a meeting with the Harvest's leader, "The Unspeakable Aklu, the Razor and the Hook," who turns out to be an actual Essiel, a renegade from the Hegemony's ruling species. Aklu offers to return the Vulture God if the crew works for the Harvest, but Rollo refuses. When the Vulture God enters the system, Rollo launches a desperate boarding action: Solace, Olli, Rollo, and Kittering board the Vulture through an umbilical while Idris fights the Harvest's interceptor. During the battle, Mesmon kills Rollo. Olli ejects the Tothiat into space, and Idris destroys the interceptor. Inside the Oumaru, the crew finds a box containing what appear to be Originator relics held in a Hegemonic suspension field, technology no outsider has ever possessed.

The crew argues over who should receive the relics. Olli fiercely opposes giving them to the Parthenon, accusing the Partheni of a eugenic ideology that would have no place for people born as she was. Solace suggests consulting Delegate Trine, a Hiver archaeologist and the galaxy's foremost Originator expert, who is stationed on Jericho, a wild colony world hosting the largest known Originator ruins.

On Jericho, Idris discovers he can sense the buried ruins through his Int abilities, the same channel that connects him to unspace and the Architects. When Uskaro's soldiers pursue them to the dig site, Idris leads the group to a buried Originator signal tower and inadvertently summons predatory wildlife that attacks their pursuers. Havaer Mundy, an agent of Mordant House, Hugh's intelligence service, arrives in the system and forces Uskaro to release the crew's impounded ship and their captured crewmate Kittering. Before they can leave, the Broken Harvest's warship emerges and deploys gravitic interdiction technology that prevents unspace transit. Idris finds a flaw in the trap and wrenches the Vulture free, but the Harvest's Ogdru navigator, a predatory alien that can track minds through unspace, pursues them relentlessly. After dozens of stutter-jumps, Idris becomes lost in featureless unspace, where the Presence, an ineffable entity all conscious beings sense in that dimension, closes in on him. On the verge of collapse, he detects a permanent scar in unspace left by the Architect's destruction at Berlenhof 50 years earlier and uses it to bring the Vulture out before losing consciousness.

The Broken Harvest catches up and captures the entire crew. Trine, who has secretly transferred the relics inside their own body, reveals a stunning finding: the Oumaru was never touched by an Architect. The wreckage was a forgery created with a gravitic drive. Trine accuses Sathiel of perpetrating the hoax to frighten humanity into joining the Hegemony. Before Aklu can execute the prisoners, a Partheni strike team breaches the ship. During the escape, Olli injects Mesmon with a biologically targeted poison via the Scorpion's tail stinger, killing the symbiote that grants his regenerative abilities. Without it, Mesmon dies. The crew escapes to the Vulture God.

In the diplomatic standoff that follows at Berlenhof, Hugh demands the return of its citizens, especially Idris, while the Parthenon insists on retaining the relics. Idris awakens and insists the Architects are truly returning despite the hoax; he sensed them moving in the deep void during his flight. Neither side believes him until news arrives that an Architect has destroyed Far Lux. An Architect then enters the Berlenhof system. The Parthenon carries Intermediaries into battle aboard the warship Heaven's Sword, armed with the relics. The Architect launches crystal soldiers, mobile puppets controlled through gravitational manipulation, that breach the ship, steal the relics, and mortally wound Saint Xavienne, the original natural-born Intermediary. Idris saves the crippled ship with a desperate jump.

The Vulture God crew then takes their ship out for a final confrontation. Idris performs continuous stutter-jumps while fighting to reach the Architect's consciousness. He breaks through and perceives that the Architects do not want to destroy inhabited worlds; they are compelled by some unknown higher power. The Architect examines Idris's memories of captivity and duress, and in a moment of mutual recognition between captives, it chooses to withdraw. Berlenhof is saved, though Idris's brain shuts down for 10 minutes before restarting. In the aftermath, Idris refuses to lead Hugh's Intermediary Program, rejecting its methods of conscripting unwilling subjects. He argues that the Parthenon's more uniform genetics could produce Intermediaries with far less loss of life and that only willing volunteers will be strong enough to face the Architects. Idris agrees to help the Parthenon develop their own program on the condition that he brings the Vulture God and its crew. Solace is assigned as the Parthenon's formal liaison aboard the ship, but the mystery of who commands the Architects remains unsolved, and the threat of their return ensures the conflict is far from over.
