It's important to know that this book addresses the homosexuality of twin 8th grade boys, both of which come out to the central character in the book. Cassie is respectful and kind to the boys and accepts them for who they are. However, the book also has a third character, named West, who it is revealed isn't sure if he is gay or bi. The confusion over sexuality may be a theme too mature for your elementary age child. The book makes no mention of these themes in the summary on the back, in the descripton on the Scholastic website or on Amazon. (Thank you Common Sense Media for mentioning this here.) The book is written on a 2.6 grade level and is a graphic novel, so odds are if it's in your child's elementary school library, your younger child could end up reading this and may not understand these parts of the story. The sexuality of the boys is a sub-theme of the book and I feel that parents should be aware of this so they can make an informed decision about whether their child is ready for this issue or not.
