FAQs – Reading Order – Lux Series

What’s the correct reading order for the Lux series to follow the story properly?

The ideal reading order for the Lux series is: Shadows (Book 0.5), Obsidian, Oblivion (1.5), then Onyx, Opal, Origin, and Opposition. Finally, read Obsession, a spinoff that expands the universe with a different perspective. This order respects the timeline and enhances the emotional arc by revealing both protagonists' inner journeys while maintaining suspense and continuity.

Is Oblivion worth reading if I’ve already finished Obsidian?

Absolutely. Oblivion retells the events of Obsidian, but from Daemon Black’s point of view, revealing his internal conflicts, fears, and emotional depth. It adds context to his behavior and choices, allowing readers to better understand his complex relationship with Katy. It’s not redundant—it’s revelatory, especially for those invested in Daemon’s character.

Should I start with Shadows or Obsidian?

Starting with Shadows offers emotional insight into the Luxen world before Katy’s story begins. Knowing what happened to Dawson and Bethany adds gravity to Daemon’s protectiveness and fears. Although not mandatory, it enriches the narrative and builds tension even before the main events of Obsidian unfold.

Does Obsession directly connect to the main series?

Yes. While marketed as a spinoff, Obsession takes place in the same universe and provides crucial context about the Arum, the Luxen's enemies. Reading it after finishing the main series gives you a fuller picture of the world’s dynamics and introduces characters that may appear in connected sagas, making it an essential addition.

How is the Lux series related to Jennifer L. Armentrout’s other books?

The Lux series is part of a broader interconnected universe created by Jennifer L. Armentrout. Although each series—like The Dark Elements or Covenant—can be read separately, they share themes, tone, and sometimes lore. Readers who start with Lux often find it the perfect gateway into Armentrout’s wider world of supernatural romance and high-stakes fantasy.
