Plot: Stargirl arrives at Mica, Arizona out of the blue. She was homeschooled her whole life. This is her first attempt at a real school. Her behaviour is unusual. Teens at Mica Area High School prize conformity above all else, but Stargirl seems not to care what anyone else thinks of her.
After 15 years of home schooling, Stargirl bursts into tenth grade in an explosion of color and a clatter of ukulele music, enchanting the Mica student body.
But then popularity suddenly shifts, and Stargirl is shunned for everything that makes her different. Somewhere in the midst of Stargirl's arrival and rise and fall, normal Leo Borlock has tumbled into love with her.
