1. Red rising
2. Golden Son
3. Morningstar
4. Iron gold
5. Dark age
6. Lightbringer
7. Red God (2026)

Edit: I do think the books are much better starting at iron gold. I liked what came before, but at times I felt like the cliches and references were a bit much. In the second trilogy I thought that issue mostly dropped away, and that the author was more comfortable in the world he built

Also, I was listening to them instead of reading, I’ve heard complaints of overly short sentence structure in the first/first few books, but the narrator smoothed over that issue gif me it seems
