No wonder there was so much unrest outside the castle, especially with the soldiers coming home. Berta glanced back at Tillie, then shoved the red slippers into her dress pocket. They could be fixed. Just because holey slippers weren’t good enough for the princesses of Myr didn’t mean they weren’t good enough for Berta.
