Justin Lee Anderson is a Scottish fantasy author best known for The Eidyn Saga, an epic fantasy series that combines a war-damaged kingdom, political conspiracy, magic, found family, and a mystery that repeatedly changes what its characters believe about their world.
His bibliography is unusually easy to separate. The Eidyn Saga is one continuous four-book fantasy story, while Carpet Diem is a completely unrelated comic fantasy standalone.

The important complication is publication history. The Lost War was originally self-published in 2019 before Orbit acquired and republished it in an expanded edition. Readers may therefore encounter both 2019 and 2022 or 2023 dates attached to the same first novel.
The Short Answer
For The Eidyn Saga, read:
- The Lost War (2019): Aranok, the first mage to serve as a King’s Envoy, leads a mismatched group across a kingdom supposedly recovering from war and begins discovering that almost nothing about the peace is what it appears to be.
- The Bitter Crown (2023): Aranok and his allies know the conspiracy controlling Eidyn is real, but exposing it means fighting a revolution against enemies who can manipulate loyalty, memory, and public belief.
- The Damned King (2025): The rebellion faces its most dangerous stage as Eidyn’s remaining defenses collapse and the surviving allies must decide who can still be trusted.
- The Bastard Throne (Forthcoming): The fourth and final Eidyn novel is intended to conclude Aranok’s war, the struggle for the throne, and the larger mystery behind the kingdom.
For Anderson’s standalone fiction:
Carpet Diem (2015): A reclusive Edinburgh man discovers that his ordinary carpet is the deciding object in a wager between God and Satan, forcing him into an absurd supernatural fight over the fate of the world.
Two Bookshelves, No Crossover
Justin Lee Anderson currently has two distinct reading paths.
The Eidyn Saga
The Lost War, The Bitter Crown, The Damned King, and The Bastard Throne form one continuous epic fantasy story.
Later books reveal the outcomes of earlier alliances, betrayals, discoveries, and character relationships. They must be read in order.
Carpet Diem
Carpet Diem is a comic fantasy standalone set in a version of modern Edinburgh.
It does not share characters, history, magic, or continuity with Eidyn.
Readers can start with either path without affecting the other.
The Eidyn Saga Books in Order
The Eidyn Saga is planned as a four-book series.
It takes place in a kingdom recovering from a devastating war. Peace has officially returned, but demons still attack farms, violent raiders roam the countryside, plague spreads through damaged regions, and political distrust remains everywhere.
At the center of the story is Aranok, a magically gifted draoidh who has achieved a position no mage before him has been allowed to hold.
The series begins like a traditional fantasy journey and gradually develops into a political mystery about truth, memory, prejudice, revolution, and the stories governments tell their own people.
1. The Lost War
The Lost War (2019): Aranok is the first magically skilled person to become a King’s Envoy in a society that still fears and distrusts mages.
His latest assignment seems straightforward. He must travel across the damaged kingdom of Eidyn, find an exiled foreign queen, and help restore her to her throne.
Aranok assembles a group whose members bring very different abilities and loyalties to the mission. Their journey crosses regions still scarred by war, where demons, mercenaries, plague, and political instability make even ordinary travel dangerous.
The deeper problem is that strange inconsistencies keep appearing around them. People behave in ways that do not fit the official story of the war, evidence contradicts accepted history, and the group begins to suspect that their mission is connected to something much larger.
This is the correct starting point for Eidyn. The novel deliberately controls what the reader knows, so later books cannot be read first without spoiling one of the series’ defining discoveries.
Which Edition of The Lost War Should You Read?
The Lost War was originally self-published in 2019.
That edition won the Self-Published Fantasy Blog-Off competition and brought Anderson wider attention. Orbit later acquired the series and released a revised and expanded edition.
New readers should choose the Orbit edition when possible.
The underlying novel is still The Lost War, so the self-published and Orbit versions should not be counted as separate books.
2. The Bitter Crown
The Bitter Crown (2023): Aranok and his companions have learned that the apparent peace in Eidyn hides a conspiracy reaching into the foundations of the kingdom.
Knowing the truth does not make resistance easy. Most of the population does not understand that it is being manipulated, and many people have powerful reasons to defend the institutions controlling them.
The group that survived The Lost War must now move from investigation toward revolution. That change places strain on friendships that were already tested by secrecy and distrust.
The conflict becomes more openly political as factions disagree over what should replace the existing order. Personal loyalty, public belief, magical power, and control of the crown all become part of the same struggle.
The Bitter Crown is a direct sequel. Its opening situation reveals the central outcome of The Lost War, so it should never be used as an alternate starting point.
3. The Damned King
The Damned King (2025): The revolution enters a more destructive phase after the protections keeping Eidyn safe begin to fail.
The eternal light that helped hold demons back has been extinguished, leaving the kingdom’s remaining strongholds vulnerable. Aranok and his allies must continue fighting political enemies while facing a more immediate threat to ordinary survival.
The group is also carrying the damage caused by earlier betrayals and revelations. Trust has become increasingly difficult when enemies can exploit divisions that already exist among the rebels.
The novel pushes the series toward its endgame by bringing the political revolution, supernatural danger, and mystery surrounding Eidyn’s history into the same conflict.
This is Book Three, not the conclusion. The Bastard Throne is planned as the final volume.
4. The Bastard Throne
The Bastard Throne (Forthcoming): The final Eidyn Saga novel is intended to conclude the revolution and the struggle over who has the right to determine the kingdom’s future.
Anderson has publicly identified The Bastard Throne as the fourth and final book.
The exact publication date is less certain. Some catalog and retailer records have displayed 2026 dates, while newer bookseller listings point to 2027. Anderson’s current official books page does not yet provide a final on-sale date.
For that reason, the safest reference listing is simply:
The Bastard Throne (Forthcoming): The fourth and final Eidyn Saga novel will complete Aranok’s story and the conflict begun in The Lost War.
Do not treat an older July 2026 placeholder as proof that the book has already been published.
Is The Eidyn Saga Complete?
Not yet.
Three books are definitely published:
- The Lost War: Aranok’s journey reveals that the peace following Eidyn’s war is built on hidden truths.
- The Bitter Crown: The survivors turn discovery into organized resistance.
- The Damned King: The revolution and supernatural crisis move toward their decisive stage.
The fourth book, The Bastard Throne, is the planned conclusion.
Readers who prefer only completed series may want to wait for Book Four. Readers comfortable with an unfinished final arc can safely read the first three in order.
Why Order Matters in The Eidyn Saga
The Lost War is constructed around uncertainty.
The reader learns about Eidyn through Aranok and his traveling companions, but their understanding of recent history is incomplete. Information that appears obvious early in the series is later reinterpreted.
The Bitter Crown begins after that reinterpretation has already occurred.
The Damned King then builds on the political and emotional consequences.
Reading the later novels first would therefore spoil more than individual character fates. It would change how the entire first book works.
Publication order is both chronological order and recommended order:
- The Lost War
- The Bitter Crown
- The Damned King
- The Bastard Throne
There are currently no published prequel novels or required novellas to insert between them.
The Lost War Publication Date Explained
Readers may see several dates for The Lost War.
2019: The original self-published edition appeared through Anderson’s independent publishing work.
2022: Orbit released a digital edition in some markets.
2023: The major Orbit print edition reached wider bookstore distribution.
These dates refer to versions of the same first Eidyn novel.
For a books-in-order page, listing The Lost War (2019) best reflects its original publication. A note about the later Orbit edition prevents readers from mistaking it for a new book.
Carpet Diem
Separate continuity
Carpet Diem: Or…How to Save the World by Accident (2015): Simon Debovar lives a withdrawn life in Edinburgh until two supernatural visitors reveal that something inside his home has extraordinary cosmic importance.
The object in question is his carpet.
God and Satan have made a wager, and ownership of the carpet has become important enough to affect the fate of humanity. Simon is forced into a supernatural conflict involving angels, demons, eccentric characters, mistaken assumptions, and increasingly absurd consequences.
The novel uses comic fantasy rather than the darker political mystery of The Eidyn Saga.
It was Anderson’s debut novel and later won an Audie Award for Humor for its audiobook edition.
Carpet Diem is completely standalone. There is no Carpet Diem Book Two.
Should You Read Carpet Diem Before The Lost War?
There is no continuity reason to do so.
Publication order places Carpet Diem first:
- Carpet Diem
- The Lost War
- The Bitter Crown
- The Damned King
- The Bastard Throne
However, readers interested specifically in epic fantasy should begin directly with The Lost War.
Carpet Diem is useful when you want to see Anderson writing comedy, supernatural absurdity, and modern Edinburgh rather than war, revolution, and secondary-world politics.

Do not insert Carpet Diem between the Eidyn novels. It is a separate comic fantasy and works best as an independent change of pace.
The Bastard Throne belongs last and will complete the four-book saga once published.
For now, the clearest order is simple: The Lost War, The Bitter Crown, The Damned King, then The Bastard Throne.
