Yaqui Delgado Wants to Kick Your Ass

Review from Booklist Reviews:

When Piedad "Piddy" Sanchez hears that Yaqui Delgado is going to crush her, she has no idea why she has become a target of one of the roughest girls in her new Queens school. But Yaqui tells everyone Piddy is a skank who shakes her ass when she walks, and as the bullying escalates from threats to physical attacks, Piddy finds herself living in constant fear. A strong student with a bright future at her old school, Piddy starts skipping school, and her grades nosedive. After a truly upsetting attack on Piddy is uploaded to YouTube, she realizes this isn't a problem she can solve on her own. Medina authentically portrays the emotional rigors of bullying through Piddy's growing sense of claustrophobic dread, and even with no shortage of loving, supportive adults on her side, there's no easy solution. With issues of ethnic identity, class conflict, body image, and domestic violence, this could have been an overstuffed problem novel; instead, it transcends with heartfelt, truthful writing that treats the complicated roots of bullying with respect.
