IWRT! (Middle grade fantasy is by the way one of my favorite genres).
I think there seems to be a a lot going on in this story. Maybe you could incorporate the themes of the novel in the blurb to give it more direction? I´m not sure if I would specify all the things Barbara must need to do to. I’m not very fond of spoilers and I think you are giving away a bit to much of the storyline. Otherwise, its great.
