Because the book announces, from the title on, that whoever "we" are, we did in fact save the kingdom, I would imagine that the book could get very dark and scary, in the way that fairy-tales do once they establish that, ah yes, the heroine surely will eventually triumph.

If I were reading the book, I would try to figure out who the "we" in the title refers to, and I'd be on the lookout for other groups who are trying to save their vision of what the kingdom is.
