Country music star Dolly Parton will make a new addition to her literary catalogue next spring with a picture book from Penguin Young Readers.

Illustrated by MacKenzie Haley, Parton’s upcoming picture book Billy the Kid Makes It Big (Penguin Workshop) follows dog Billy, a country star hopeful, as he heads off to Nashville to achieve his dreams. When Billy faces off against mean dogs with their own musical ambitions, he will have to rely on new friends he’s made along the way and his love of music to succeed. The book will publish on April 25.

Parton’s pup-filled picture book pulls inspiration from her real-life “god-dog” Billy. “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,” Parton said in a statement. “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.”

This new book aligns with Parton’s many endeavors in the literacy and education space. Her Imagination Library, a program providing free books to families across five countries, has donated more than 190 million books since its inception in 1995. Recently, Parton was the recipient of a $100 million gift from Jeff Bezos, to donate to charities of her choice.
