I wish there had been more detail about the mother's illness; it was very serious, and it was good that the girls had their grandmother step in, but I wanted to know more about the nature of her illness.
Like Rosenberg and Shang's upcoming Not Your All-American Girl (July 7th 2020, Scholastic Press), this covers a play and outdated social expectations for casting. Since this is set in the present rather than the 1980s, the teachers involved are open to changing the play, and even breaking with tradition and trying a new play. I remember watching Peter Pan with my own children twenty years ago and thinking "Oh. This is problematic!" Still, the plays that schools do seem to be stuck in the 1960s, so it's good to see a critical examination of these choices through a modern, racially sensitive lens.
