Why I think the Valkyries subtitle doesn’t mean it’s particularly a Valkyries centred book
I think that a series title very often has very little to do with the plot overall and it’s more to do with what is a catalyst and it’s very possible the Valkyries and the events in ACOSF kicked off this whole set of books or this ‘era’. But I was thinking about the following;
The Eating Woods (a conduit between worlds but the plot not based solely on it and infact you spend very little time there at all)
The Empyrean- is not any main plot force they’re a background political organisation related to but isn’t the main driving force of the plot. Our main characters are mostly outside of it entirely
Crowns of Nyaxia - Not about nyaxia. She’s a trigger and shows up sporadically.
I know people have shared other theories that it’s also going to be mostly based around the Valkyries opera that is about forbidden love. I just think the blurb told a very different story and I’m not entirely sure this is a literal subtitle.
