Haven't read chapter 6 yet.
I had a question about structure though. First, did you realize there is no chapter 1? What's in the "chapter 1" file is labeled "Prologue." Should we conceptually treat it as a prologue, or as chapter 1?
After reading chapter 5, the structure struck me as a little odd, that we get one chapter from the blood sword guy's point of view, then three from Siri and her family, then a new one from a totally different point of view. Is the prologue guy going to be a main character or not? And why have those Siri family bits split up into three chapters?
As for the cook...she immediately struck me as suspicious, like she's the replacement for the old man in Mythwalker, and all his hidden baggage. Otherwise, why is she there? Except for my exposure to too many Brandon books, though, she doesn't bug me at all.
My 2-years younger sister (who was like a middle child because my older sister is 5 years older than me) always had to do everything at the same time I did. However, my youngest sister is three years younger than that, and I'd say she always did seem young, though perhaps only in comparison to my younger sister at that age.
