I feel like this could have used the verse form more. Verse is most useful to convey emotions, rather than events. The story had some twists and it was good that it was conveyed without breaking the flow too much. However, I've read and seen other works (e.g. Turtles All the Way Down and Inside Out 2) that give a better picture of what a panic attack feels like. It was unusual to see verse used in such a didactic book, as well.

There was a certain "fellow kids" factor where it was clear that the author was writing about a different generation and getting some things second hand.

I enjoyed how the story showed Sadie's family members coping with her anxiety. They all loved her, but had varying levels of maturity, understanding, and patience.
