Five-year-old Catie is on her way to kindergarten for the first time. A shy little girl, she's a bit nervous. The first day of school goes well, but it's the second day, the third day, and the fourth day where trouble arises.

Each day while playing outside her home with her dog, Catie is shoved by a bully named Nancy. Each time, Nancy pushes Catie to the ground, and Catie gets up and dusts herself off. She's much too shy to say anything to anyone. On the fifth day, another girl intervenes; Sklyar instructs Nancy to stop being mean and to quit bullying Catie.

Catie's First Day of School, a picture book for children, shares a heartwarming story of how friends can help put a stop to bullying.
