All right, the main characters' brothers are significant, but they're all dead to start the party rolling. And there will be other male characters, but none continuing the way the characters known to be female are. . . .
So is this going to be a straightforward heroines vs. villainesses story? (Well, actually, villainess vs. different villainesses vs. heroines. . . )
Well, we'll see. Probably should spend more time worrying about whether the villainesses get points of view or whether the readers should learn their plots as the heroines do.
