Idina and sister Cara Mentzel Pen Picture Book!

Loud Mouse

Idina and her sister Cara Mentzel have written a children’s book! Loud Mouse is the story of Dee, a mouse who loves to sing. She sings during her morning yoga. She even sings while practicing her math facts. She usually sings to herself. But when her teacher asks everyone to share something with the class, Dee knows just what to bring: a song. And as Dee sings la, la, la, la, LOUDly in front of her class for the first time, something extraordinary happens.

Loud Mouse is published by Disney-Hyperion and will be released on September 27. Read Idina and Cara’s exclusive interview about the book at
