Saige by Jessie Haas

Ten-year-old Saige Copeland loves spending time on her grandma Mimi's ranch, riding horses and painting. Her school made the tough choice to cut art classes, which means she's lost her favorite subject. So when Mimi decides to organize a "save the arts" fundraiser and parade to benefit the school, Saige jumps on board. She begins training Mimi's beautiful horse, Picasso, for his appearance in the parade. Then Mimi is injured in an accident, and Saige wonders what she can do to help. Can she ride Picasso in the parade and make her grandma proud? Can she still raise money to protect the arts at school?
