The story is realistic with a twist of magic as the two woman are only seen by Bee. Themes of bullying, inclusion versus exclusion of special needs kids, handicaps, and standing up for oneself are some topics that can be discussed. The character of Bee seems too young at times, especially at the start of the novel, but she is socially stunted because of her birthmark, that makes her avoid people in general, so perhaps this was done on purpose by the author.
Some might not like how Bee handles the bully in the story, although it is authentic in how kids handle situations like Bee's. Bee gets information on the bully and says mean and hurtful things right back because she's tired of being attacked verbally and physically. Bee reflects on her actions later with another adult and wonders if it was the best thing to do in the end. Many of the adults in the beginning of the story come across as one-dimensional and it isn't until the second half that some become more complex and interesting. A nice debut novel.
