Yaqui Delgado Wants to Kick Your Ass is a new book by Meg Medina. It's been showing up on many of the "Best of 2013" lists. It is a very realistic "problem" novel.
Piddy is the new girl at Daniel Jones High School. She is Latina, as is the author. On one of the very first days of school a girl that Piddy doesn't even know bumps into her and says "Yaqui Delgado wants to kick your ass!" Piddy doesn't even know who Yaqui is....much less why she wants to beat her up. What follows is a very realistic book about bullying. Piddy has to decide what she is willing to do to protect herself. She is a smart girl, but there are no easy solutions. Does she want to get the school administration involved? Will that make things worse? You'll have to read the book to see how she deals with Yaqui.
