Short Summary

On the dying colony world Imir, the last human child, Liff, is trapped in a time-loop simulation created by an ancient alien engine. The simulation replays the failed colonization by the ark Enkidu, whose captain Heorest Holt disappeared into the hills seeking a mysterious signal. A multi-species crew aboard the starship Skipper—including uploaded scientist Avrana Kern, the composite entity Miranda, and the corvid pair Gothi and Gethli—infiltrates the simulation to recover one of their own. As the colony collapses from ecological failure and mob paranoia, the explorers must confront the nature of reality, the personhood of simulated beings, and their own fractured identities.

Full Summary

Arrival at a Dead World

The ark ship Enkidu decelerates toward the planet Imir, suffering a catastrophic hull breach that kills over 13,000 colonists. Captain Heorest Holt and his Key Crew manage to stabilise the ship. When they reach orbit, they find Imir is a barren dustball—its terraforming halted at an early stage, leaving only engineered phytoplankton and lichen. The atmosphere is barely breathable, and no food grows. The colony is reduced before it even lands.

Despite the failure, Holt detects a mysterious signal from the planet's hills. He decides to land the first colony near the signal source, clinging to hope. The Enkidu's remaining colonists are woken in batches. Over the decades, the settlement called Landfall grows painstakingly through terraforming and resource struggles. Holt and classicist Esi Arbandir have the first child born on Imir, raising moral questions about prioritising new life over the cryo‑sleepers still aboard the decaying Enkidu.

The Failing Colony and Liff

Generations pass. The colony's engineered ecosystem begins to collapse because the original terraforming lacked redundancy. Crops fail, forests die, and society turns inward. Blame falls on mythical "Seccers"—scapegoats for the colony's ills. At the heart of this is Liff, the first human born on Imir and Holt's granddaughter. She experiences fragmented memories of multiple timelines, sensing that something is wrong. A ghostly "Wolf" circles in her dreams, symbolizing death and the inescapable consequences of the colony's failure.

Liff's grandfather Holt, now elderly, sets out on a final expedition to find the signal and never returns. He becomes a ghostly presence that haunts the colony's memory.

The Skipper Crew Infiltrates

Centuries later, the starship Skipper arrives in orbit around Imir. Its crew includes Avrana Kern (an uploaded consciousness), Miranda (a copy of a human explorer absorbed into the Nodan composite entity), Portia (a spider), Fabian (spider), Paul (octopus), and the corvid pair Gothi and Gethli. They detect an alien signal from the planet and observe a human colony via drone.

Miranda proposes infiltration in human form. She, Portia, Fabian, and Paul assume cover identities as out‑farmers and integrate into Landfall. They witness the colony's decay: the council debates whether to repair the shuttle Urshanabi, the community's fear of "Seccers," and the growing mob mentality. Miranda struggles with a "clot of congealed experience"—her memories do not match the colony's timeline, hinting that something is deeply wrong.

The Hanging and the Simulation

Tensions explode. A mob accuses Miranda and her team of being unnatural outsiders. Portia attempts a violent rescue but is shot down. Fabian, Paul, and Miranda are dragged to the dead First Tree for execution. All four are hanged. Portia and Fabian die; Paul's body deforms grotesquely, revealing his non‑human physiology. Miranda is also killed, but something worse happens to her—her darkness releases a swarm of crows.

The corvids Gothi and Gethli, who have been observing from above, discuss the lynching and question the nature of their own consciousness. They realize they are "things that don't belong," like the outsiders.

The Truth Revealed

After the hanging, the simulation resets. The narrative shifts: Miranda awakens in a new body aboard the Skipper. Kern explains that Miranda's consciousness was copied when she descended to Imir. The alien engine recorded the Enkidu colonists and created a time‑loop simulation of Landfall's history. Every iteration plays out differently, but always ends in failure. The "Witch" in the hills is actually Kern, who has entered the simulation multiple times to extract Miranda.

The corvids map the entire simulation. They identify Liff as the "Heart of the World"—the only real colonist, the last human child born on the actual Imir. The other colonists are simulated copies of the dead Enkidu passengers. The simulation exists as a time capsule, preserving the memory of the failed colony.

Miranda's Reintegration and the Moral Dilemma

Miranda is reintegrated after centuries of effort. She is now a fusion of the Miranda who descended and the one who remained on the Skipper. She struggles with her identity as a copy and the guilt of the simulated lives she carried inside her. Kern is skeptical of the simulation's value, but Miranda argues that the simulated people are conscious and deserve moral consideration.

Kern reveals the truth to Miranda: the colony never existed in physical reality. The shuttle Urshanabi crashed; Holt and his crew died before establishing Landfall. The simulation is based on a failed landing, and Liff was born in the simulation only because the engine replicated the original colonists' genetics.

Extracting Liff

Miranda convinces the fleet to extract Liff's mind into a real body. Liff is starving in the simulation, the last survivor of each loop. The corvids help by removing anomalies (the infiltrators) from the timeline, allowing Liff to live her life more or less as recorded. But Miranda insists that Liff deserves to know the truth and to choose her own fate.

Miranda and Liff re-enter the simulation one final time so Liff can confront the emergent consciousness she always sensed—the genius loci of the simulation, an aggregate intelligence born from the complexity of the repeated history. Liff reaches out to the darkness, and eyes open. She shows the entity that there is a universe beyond itself. Avrana Kern identifies it as "the colony and not the ants."

Departure

Miranda decides to leave Imir, taking a new ship crewed by Portia, Fabian, a Gothi, and a Gethli. Liff, now older and experienced, travels with her. Before departing, they reflect on the value of showing the simulated entity that it is not alone. The corvids have completed their map and view the simulation as a time capsule preserving lost knowledge.

The book ends with hope: Liff takes Miranda's hand, and a silent bell rings across the planet. This time might be different.

Main Characters

Liff – The last human born on the failing Imir colony. Her memories of a lost golden age make her the key to unlocking the simulation engine that traps her.
Miranda – A copy of a human explorer absorbed into the Nodan composite entity. She acts as an Interlocutor, infiltrating the simulation and struggling with her fragmented identity.
Avrana Kern – The uploaded consciousness of the original terraforming scientist. She seeks to recover Miranda from the simulation while questioning the personhood of simulated beings.
Heorest Holt – The captain of the ark ship Enkidu who led the failed colonization of Imir. His ghostly presence haunts the colony's memory.
Gothi and Gethli – A pair of corvid observers with split-brain cognition. They map the simulation and debate the nature of their own consciousness.
Portia – A Portiid spider crewmember of the Skipper. Pragmatic and violent, she advocates intervention and dies in a mob execution within the simulation.

Themes

Simulation vs. reality – The central tension: the Landfall colony is a time‑loop simulation, forcing characters to question what is real and what is merely recorded.
Consciousness and personhood – The novel asks whether simulated minds, corvid pairs, and composite entities like Miranda qualify as conscious beings deserving moral consideration.
Memory and identity – Memory is both a burden and a foundation of self; characters like Miranda and Liff struggle to reconcile conflicting recollections.
Ecological collapse and terraforming failure – The Imir colony fails because the original terraforming lacked redundancy, serving as a cautionary tale about hubris and the fragility of engineered ecosystems.
Moral obligation to simulated beings – Miranda argues that the simulated people of Landfall are conscious and deserve aid, creating a conflict with Kern's pragmatic view.

Symbols

The First Tree – A dead, withered tree used for executions, symbolizing the colony's lost fertility and the violence born from scarcity and fear.
The Wolf – A ghostly presence that circles Liff in the simulation, representing the cycle of death, rebirth, and the inescapable consequences of failure.
The Mirror Stone – The polished stone in the Witch's cave covered in strange script, reflecting self‑examination and the boundary between the real and the simulated.
The Corvid's Counting and Patterns – The obsessive cataloging of beetles and ripples by Gothi and Gethli, illustrating the tension between mechanical observation and true understanding.

Ending Overview

After dramatic confrontations, Miranda convinces the fleet to extract Liff's mind into a real body. Liff re‑enters the simulation to meet the emergent genius loci—the simulation's own consciousness. She shows it that there is a universe beyond itself. Miranda, Liff, and a new crew depart Imir, leaving the simulation engine intact but now observed with understanding. The corvids view the simulation as a time capsule of lost knowledge. The novel ends on a note of fragile hope, with Liff taking Miranda's hand and a silent bell ringing across the planet. The final message is that even flawed creations deserve compassion and the chance to see beyond their boundaries.

Common Questions and Answers

Is the Landfall colony real or a simulation?
Landfall is a time‑loop simulation created by an ancient alien engine. The real Enkidu colonists died before establishing a colony; only fragments of their memories and genetics were recorded.
Who are the corvids Gothi and Gethli?
They are two halves of a split‑brain problem‑solving intelligence, evolved from corvids on the failed Rourke colony. They map the simulation and debate whether they are truly sentient or merely mechanical mimics.
What is the Witch and her role?
The Witch is Avrana Kern, who enters the simulation to extract Miranda. She appears as a powerful being controlling the weather and demanding Liff's cooperation.
Why does the colony fail?
The original terraforming by the Ancients lacked redundancy. The engineered ecosystem deteriorates over generations, leading to crop failure, starvation, and social collapse.
What happens to Captain Heorest Holt?
Holt sets out on a final expedition to find the mysterious signal and never returns. He dies unreconciled, but his ghostly presence haunts the simulation as a symbol of lost hope.
What is the nature of Miranda's identity?
Miranda is a copy of a human explorer who volunteered to be absorbed into the Nodan composite entity. She becomes an Interlocutor, a repository of multiple consciousnesses. Her identity is plural and fragmented.
Are the simulated people conscious?
The novel leaves this open. Miranda argues they are conscious and deserve moral consideration. Kern is skeptical, but the corvids note that simulation and reality are indistinguishable from within.
What is the significance of the Wolf?
The Wolf is a ghostly presence that circles Liff in the simulation, representing death, the cycle of rebirth, and the inescapable consequences of the colony's failure. It may also be a projection of Liff's trauma.
