Dolly Parton has a new children’s book Dolly Parton’s Billy the Kid Makes it Big comes out next year.

She tells People, “When I launched the Doggy Parton line of pet products earlier this year, my god-dog Billy got to be the star of the show. Since he’s a big star now, I knew a story with him at the center could help drive home important messages in a unique way. I hope this is the first of many books with Billy.”

The book’s star, Billy the Kid loves country music and wants to be a country star in Nashville.

Dolly Parton’s Billy the Kid Makes it Big comes out on April 25th.
