My Name Is Maria Isabel

For Mar�a Isabel Salazar L�pez, the hardest thing about being the new girl in school is that the teacher doesn't call her by her real name. "We already have two Mar�as in this class," says her teacher. "Why don't we call you Mary instead?"
But Mar�a Isabel has been named for her Pap�'s mother and for Chabela, her beloved Puerto Rican grandmother. Can she find a way to make her teacher see that if she loses her name, she's lost the most important part of herself?
