Two series, one world, and a prequel that will absolutely spoil you if you read it too early. Here's how to read Blood and Ash and Flesh and Fire in the order that keeps every reveal intact.

Why This Order Actually Matters
Most series reading orders are a convenience. This one is a spoiler shield.
Flesh and Fire is a prequel set centuries before Blood and Ash, and on paper that means you could start there. You shouldn't. The prequel casually confirms things the main series spends three books carefully building toward — read it first and you'll walk into major reveals already knowing the answer.
Here's the sequence that protects the story.
Blood and Ash, In Order
Poppy and Casteel's series, five books:
- From Blood and Ash
- A Kingdom of Flesh and Fire
- The Crown of Gilded Bones
- The War of Two Queens
- A Soul of Ash and Blood
A note on book five. A Soul of Ash and Blood retells the events of book one from Casteel's point of view. It's not a plot continuation, so it can wait — but it lands best after The War of Two Queens, when you already know what he was hiding the whole time.
Flesh and Fire, In Order
Seraphena and Nyktos's prequel series:
- A Shadow in the Ember
- A Light in the Flame
- A Fire in the Flesh
- Born of Blood and Ash
The Combined Order (Recommended)
The two series were written to be read together, roughly in release order. This is the version most readers land on after finishing everything:
- From Blood and Ash
- A Kingdom of Flesh and Fire
- A Shadow in the Ember (start the prequel here)
- The Crown of Gilded Bones
- A Light in the Flame
- The War of Two Queens
- A Fire in the Flesh
- A Soul of Ash and Blood
- Born of Blood and Ash
The logic: you need two full Blood and Ash books before the prequel means anything, and after that the two timelines start feeding each other. Reveals in one series recontextualise scenes in the other — which is the whole appeal, and only works if you alternate.
Can You Just Read One Series?
Yes, with a caveat.
Blood and Ash alone works fine as a complete story. You'll miss the deeper mythology, but nothing is unresolved.
Flesh and Fire alone doesn't. It's built as a companion, and its emotional payoffs depend on knowing where this world ends up. Reading it in isolation is the one approach we'd actively steer you away from.
What You're Getting Into
This is fated mates territory with a heavy political layer — closer to our fated mates picks than to contemporary dark romance. The spice climbs steadily across both series, landing solidly mid-to-high on the spice level scale by the later books.
Expect long books, slow political build, and a romance that stays central rather than getting buried under the plot.
Where to Go From Here
If you've finished both series and want something with the same scale, our best fantasy romance series to binge list leans toward exactly this kind of multi-book commitment. For the broader genre map, the romantasy reading order guide covers the other major series worth starting.
