Idina & Cara Announce ‘Loud Mouse’!

Idina Menzel and her sister, Cara Mentzel, announced their new children’s book called Loud Mouse in an exclusive interview with PEOPLE! Loud Mouse is an illustrated book for kids ages 3-5 and will be released on September 27! Here’s the adorable synopsis:

Dee 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. . . .

They also shared that Idina is recording a song for the book! Idina told PEOPLE that Cara said, “Just don’t write a song that people like me and moms and teachers can’t sing.” Pre-order Loud Mouse now!

Here’s what they each had to say on Twitter today:
