One morning before school, some girl tells Piddy Sanchez that Yaqui Delgado hates her and wants to kick her ass. Piddy doesn't even know who Yaqui is, never mind what she's done to piss her off. But as the harassment escalates, avoiding Yaqui and her gang starts to take over Piddy's life. In an all-too-realistic novel, Meg Medina portrays a sympathetic heroine forced to decide who she really is.
