Levine, G: Wish

Wilma Sturtz is invisible and miserable at school. So when an old lady on the subway offers her a wish, Wilma immediately asks for popularity -- in fact, she asks to be the most popular kid at school. Suddenly, Wilma has more friends than she can keep track of, forty dates to the Grad Night Dance, and a secret admirer writing her love poems. Everything is great, until she realizes there's a loophole in her wish, and her time in the spotlight has almost run out.
