Leo Borlock is a median pupil at Mica Excessive Faculty. He will get first rate grades, is a member of the college's marching band and has at all times been content material flying beneath the radar. However all that adjustments when he meets Stargirl Caraway, a assured and colourful new pupil with a penchant for the ukulele, who stands out in a crowd. She is variety, finds magic within the mundane and touches the lives of others with the only of gestures. Her eccentricities and infectious character allure Leo and the coed physique, and he or she rapidly goes from being ignored and ridiculed to accepted and praised, then again once more, sending Leo on a rollercoaster trip of feelings.
