Glass Slippers (Sisters Ever After #2)

The second book in the Sisters Ever After series of fairy tale retellings from the point of view of the siblings in the background, this is the story of Cinderella's never-before-mentioned third evil step-sister, Tirza.

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 on young Tirza. She 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 now 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.
