I think this one started off great but sort've lost steam by the end. Everything I think would've been fun/interesting/upbeat was hidden behind a time-jump with some light mentioning of what had transpired.

I think in general Seanan seems to have an idealized view of sibling relationships? Just each time something bad happens it's for the sake of a sibling relationship a la Jack and Jill and now Lundy and her little sister.

Just... yeah, I would happily trade any of my little brothers to live in a fantasy land that loved me. LOL. Also doubly so if my sibling also happened to be a murderer, but whatever.
