As I read this well-written middle grade novel, I couldn't help thinking of Cynthia Lord's Rules, which covers similar territory, only in this case, Jacob, the protagonist's brother, is two years older than she is rather than younger as David is in Rules. While there's no possible romantic interest as there was between Catherine and Jason, there is a new friend, Charlie, who is blind. in this book, set in Prue, Oklahoma, eleven-year-old Olivia Grant is starting to chafe at the challenges and restrictions caused by life with her thirteen-year-old brother Jacob, who is on the autism spectrum. To Olivia, his behavior seems to be getting worse and more embarrassing, especially now that he's lost his beloved stuffed ostrich. Olivia, who is known for finding lost things, becomes increasingly determined to find that toy so that Jacob will start to behave more normally. She enlists the help of Charlie, the zookeeper's son. A part of the zoo has been parceled out to small communities like Prue while the main one in Tulsa is being renovated, and Olivia's trespassing at the zoo site leads to her being assigned community service hours. Although she loves her brother, she desperately wants to have something that is her very own, an ambition that is thwarted when she tries out for a role in the community theater production of Peter Pan, and her parents insist that Jacob should be allowed to participate as well. The author does an excellent job of describing how Olivia's moment of triumph is ruined by Jacob's unhappiness about wearing itchy jeans as well as depicting Olivia's own fears that her behavior might be signs of latent autism. The author doesn't miss a beat here in creating a loving family under pressure but trying to support one another as much as possible. Olivia's harsh words to her brother and her lack of empathy toward him and Charlie at times seem realistic. The only thing that made me wince was how often Jacob was referred to as autistic rather than having autism. This title is sure to open up some hearts and minds while also presenting much food for thought and discussion about what being normal is. As I read the book, I kept thinking of Jacob's remarks about the true colors of trees being revealed in the fall and how all of us are a little bit lost and a little bit found as Olivia comes to realize.
