Very sweet story about non-conformity, popularity and love. The narrator, Leo, tells the story of Stargirl, and homeschooled free spirit who starts at his highschool her sophomore year. Stargirl wears prairie dresses, caries around a pet rat, plays the ukulele and sings happy birthday to each student on his or her birthday. At first the other students are amused and enamored, but then the tide turns and she becomes an outcast. Of course by this point Leo is totally in love. 
 UTA: I just realized Stargirl = Luna Lovegood!
