I've dropped the book after the reveal of the Amazon heritage, but I have fianlly thought of a way to fix their history without a massive retcon.

I wouldn't have minded the whole thing being a lie, because I don't mind the gods not being affected by the lasso. But then how do you explain the Amazons? It occured to me after a while it had been a long time since Diana had been to THemiscrya, so they could be fake.

Some of the history would have to be real, but it could be a Potemkin Village sort of thing to get Diana to go along with some godly succession crisis without realizing it.
