Award-winning author-illustrator Ryan T. Higgins presents this headbanging companion to the #1 New York Times best-selling We Don't Eat Our Classmates.

Penelope is a T. rex, and she's very good at it. She also likes to rock out on guitar! With the school talent show coming up, Penelope can't wait to perform for her classmates. But sharing who you are can be show-stoppingly scary, especially when it's not what people expect. Will Penelope get by with a little help from her friends?
