Her name is Stargirl, and she is as unusual as her name suggests. When Stargirl arrives at Mica High, she quickly rises from an unknown oddity to a beloved popular teen. She just as quickly becomes the most disliked student in school.
We meet Stargirl through Leo, another student at Mica High. Leo and Stargirl fall in love. When she (and, by association, Leo) is shunned by their classmates Stargirl allows Leo to talk her into conforming to their normalcy.
This was a quick read. There is a sequel (Love, Stargirl), which I have waiting at home for me to read. Although the main characters are in high school, I’d offer it to students from about 6th grade up.
