The silver spurs of Oz

"Cowgirl Dorothy and her horse, Toto, are taking the Yellow Dust Road on the way to the Great Wiz Kid's Emerald Circus of Oz for auditions, and along the way she meets Tinny, Crow, Leo, and Strega West who are also looking to audition--but in the morning Strega has disappeared, along with Dorothy's lucky silver spurs, and Dorothy must summon her inner courage to perform her best at the audition"--OCLC.
