The seven books

One for each way the world can get to be a lot

The first six follow the same shape: Zola's noticing is a gift, then it becomes too much, then a grown-up gives her a real tool — and she uses the very thing that overwhelmed her to help somebody else. In Book 7 the shape turns around: on a foggy mountain it's Dad who gets lost, and everything Zola noticed on the way up leads them both home.
