Rachel's life was very privileged, and she was able to go to the mall to get all new clothes. This might seem odd to many students; I know that I wore a lot of my mother's clothing when I wore a back brace in the 1970s. In fact, most of my objections were based on my own experiences having scoliosis when I was about Rachel's age, since my experience was rather different. I guess that I just want to see several more novels on this topic so that readers can see a variety of experiences presented.
There are not as many books involving medical problems as I would live to see, so there are a lot of one sided stories. This author covers ADHD admirably in Focused, and her work is good to add to a list of books about illness that include Blake's Ivy Aberdeen's Letter to the World, Behar's Lucky Broken Girl, and of course, the works of Lurlene McDaniel.
