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?
