Estrella Alvarez is turning fifteen, and she's not happy about it. For as long as she can remember, her mother has been planning an elaborate quinceañera, complete with a mariachi band, cheesy decorations, and a hideous dress. Estrella is so over it. She'd much rather have an understated dinner party at a posh restaurant downtown -- that way, she can invite her two best friends from private school, who have no idea Estrella lives in the barrio. Even though Estrella tries to keep her home life a secret from her school friends, things get even more complicated when she falls for Speedy, a cholo whom her new friends -- and her parents -- would definitely disapprove of. Caught between her family's wishes and the allure of her sophisticated friends, Estrella is forced to make some tough choices.
