Jessi loves ballet and she loves kids! So, when she is asked to help out with a class for children underprivileged to learn ballet, Jessi is all for it. She figures it is a way to combine her two interests plus maybe get to become friends with some of her ballet classmates. And she does, but Jessi learns a secret about one of the girls, Mary. Mary is going something that could hurt herself and maybe even kill her. Jessi is torn. If tells someone about Mary's condition, she could lose Mary as a friend. But if Jessi lets it go, Mary could die. What will Jessi do? Unlike most BSC books, I wouldn't say the story ends well. It's bittersweet. In the end, things turn out alright, but not perfect. The author writes this book masterfully. She lets the reader see the gradual effects of anorexia, how is starts out so subtle but after a while it begins to take its toll on someone's health and happiness. I thought this book was good. Although sad, I believe every kid should read this. I suggest if you like babysitting, friendship, ballet, and being a true friend.
