My Louisiana Sky is a coming of age tale with a twist. Tiger Ann Parker is a girl experiencing the summer before seventh grade in a small Louisiana town. Tiger begins to show signs of adolescence when her interests suddenly change from playing baseball with the boys to an interest in sophisticated fashion and seeking the approval of a popular classmate named Abby Lynn. Tiger also admires Aunt Dorie Kay, who lives in the city and buys the Parkers a TV set, which is a rare treat for most families in the area. Tiger becomes self-conscious about her developmentally disabled mother, who embarrasses Tiger at the school gymnasium. Tiger also hopes for an invitation to Abby Lynn's pool party, but Tiger is hurt and disappointed when she realizes that she was not invited. Her best friend, Jesse Wade, received an invitation but left the party once he realized that Tiger was not invited. Tiger begins to cry after Jesse explains the situation. Jesse comforts her then kisses Tiger on the lips. Tiger later confesses to Granny about how Tiger feels about her mother. Granny consoles Tiger and offers advice and solace. Tiger's world is shaken when her grandmother suddenly passes away. Aunt Dorie Kay returns to Saitter to make arrangements for the funeral, since Tiger's parents cannot. During her stay, Dorie Kay takes Tiger out to a movie and invites Tiger to stay with her permanently. Tiger has mixed emotions about leaving her parents, but she is excited about the prospect. She visits with Dorie Kay in Baton Rouge for a few days to see if she likes it. Tiger swims in the large pool and gets a haircut in the Audrey Hepburn style. Tiger returns home with Dorie Kay's maid, Magnolia, and is surprised that she missed her home. One evening, Lonnie notices that the birds are acting strange. The next morning, the cows act abnormally. Lonnie tells Mrs. Thompson, owner of Thompson Nursery and his employer, that a storm is on the horizon and the plants should be brought inside. Mrs. Thompson believes Lonnie, and the plants are brought inside of the Thompson house. Lonnie sends Tiger home to be with her mother, but Tiger returns home to find that her mother has gone out to look for Tiger. Tiger rushes back outside to search for her mother. When they find each other, Tiger appreciates how much both of her parents love her, and how much she loves them back. Tiger makes the decision to stay with her parents and help take of them. Aunt Dorie Kay tells Tiger that Tiger has grown up.
