Reading Order Notes
These The Empyrean reading order notes help first-time readers avoid the most common mistakes: starting in the wrong place, treating Threshing Day like Book 4, or assuming the series is finished.
Why publication order works
For most readers, publication order is the best The Empyrean reading order because each novel builds directly on the last, and the companion collection is optional rather than part of the main five-book plan.
Can you start with Iron Flame?
No. Iron Flame is a direct sequel to Fourth Wing, so skipping it would break the main story and make Onyx Storm much harder to follow.
What is Threshing Day?
Threshing Day is a companion collection with 13 stories scheduled for September 29, 2026. It is not Book 4 and should not be counted among the five main novels.
What is the safest first-time path?
Start with Fourth Wing, continue through Iron Flame and Onyx Storm, then read the remaining untitled main books when they are released. Read Threshing Day afterward if you want the companion material.

Frequently Asked Questions
What is the correct The Empyrean reading order?
The correct reading order is Fourth Wing, Iron Flame, and Onyx Storm for the published novels so far. The planned main series continues with two untitled books, and publication order is still the best first-time path because it keeps the reveals, emotional development, and worldbuilding progression intact.
Is The Empyrean series complete?
No. The Empyrean is not complete yet. The series is still ongoing, the main series is planned as five books, and Onyx Storm currently serves as book three.
Should I start Rebecca Yarros with The Empyrean?
Yes, if you want to start with her biggest romantasy series. Fourth Wing is the natural entry point because it introduces the world, the central cast, and the series stakes from the beginning.
Can I skip Iron Flame?
No, not if you want the main story to make sense. Iron Flame is a direct continuation of Fourth Wing and sets up Onyx Storm, so skipping it would mean missing key plot turns and relationship development.
What is Threshing Day?
Threshing Day is a companion collection scheduled for September 29, 2026. It includes 13 stories and should not be treated as Book 4 of The Empyrean or counted among the five main novels.
Is Threshing Day Book 4?
No. Threshing Day is a separate companion collection, not Book 4 of The Empyrean.
Can I wait for Threshing Day before starting The Empyrean?
You can wait if you prefer to binge more material at once, but you do not need to wait. Start with Fourth Wing if you want the main story now, and treat Threshing Day as optional companion material.
