Loved the introduction. Put me in mind of Pullman talking about his Dark Materials series.
The breadth of vocabulary of the characters, and the way a precocious child can struggle with structured schooling is depicted puts her writing where her mouth is, and I applaud it. Oh, and the frustration with adults! I would have loved this when I was a kid. Even more, the variety of sentiments in those adults causing the frustration, from the truly empathetic (but sometimes you want nothing but to rage) to the fake/managing ones (that kids instinctually pick up on most times).
