Junia is a mule. But she's not just any mule. She's a mule with an important job. Every morning she carries her Book Woman up and down the rugged hills and surrounding woodlands near the Kentucky town of Troublesome Creek. Book Woman is a Pack Horse librarian. She and Junia deliver free books and reading material to the people living in the hills and woods. It's not easy work. Every month they ride hundreds of miles to make their deliveries. The story of Junia comes to vivid life for young readers in this picture book tribute to Kentucky's Great Depression Pack Horse Library Project.
