Fourteen-year-old Jenny shares her daily life with her diary "Dee." Jenny's younger brother Ezra is a common topic. You see, Ezra has autism and Jenny feels connected to him by an invisible cord which helps her keep track of him and his moods. Jenny also feels responsible for keeping Ezra out of trouble and for protecting him from those who don't understand Ezra's actions and autism.
However, Jenny also wants to do all of the things that the other 14-year-old girls are doing at her school without having to worry about what's going on with Ezra. While she is proud of Ezra and all of the things he has accomplished and learned, she still sees all the situations in which he still has trouble and worries that if she were to go away to camp for the summer that things might go badly at home.
Jenny's feelings are typical for siblings of those with autism. This diary is a great way for them to explore their feelings about their autistic siblings and to learn that they are not alone in perhaps having feelings of both pride and resentment at the same time. Told with frankness and humor, Autism, the Invisible Cord, a Sibling’s Diary is a short and enlightening read for those with connections to autism.
