Frozen's Elsa and Tony Award-winner Idina Menzel, along with acclaimed writer and teacher Cara Mentzel, present a lyrical picture book about a proud sister learning to find her own way.

Cara Lee is a proud mouse. She is proud of her big sister Dee. She is proud of her specially decorated journal. And now she's proud to become what she's always wanted to be: a student. But her first day of school is different than she imagined. Everyone keeps comparing her to Dee. But who is Cara Lee? When you have a big sister with such a LOUD talent, how can you find room to shine in your own way?

Complete with gorgeous illustrations and filled with humor and heart, Proud Mouse is a clever tale about celebrating the things that make you YOU and having the confidence to stand loud and proud.
