Originally published in hardcover in the US by Delacorte Press, New York, in 2022.

Meet Cinderella's third "wicked" stepsister, Tirza. For years, Tirza has lived with the shame of what her family did to Cinderella. Against everyone's advice, Cinderella -- now Queen Ella -- took a chance and gave Tirza a home in the castle instead of banishing her. The queen told everyone Tirza was good and kind, not cruel like her older sisters. But when Queen Ella's famous glass slippers are missing, and there's only one suspect. Tirza may have tried them on... but she didn't steal them. Now she must find the true thief before she loses her royal home. But as Tirza gets closer to the truth, she finds herself getting closer to something else: her sisters, who might not be quite as evil as Cinderella claims.

Ages 8-12.
