After a joyful day, Emerald feels heavy and sad at bedtime, wondering if something is wrong with her. Her parents explain the “window of resilience,” but Emerald doubts their words. Guided by Sapphire into the Queen’s magical maze, Emerald faces challenges that shrink her window and learns how to open it again—through rest, good food, breathing, and remembering she is loved. With the Queen’s final lesson, Emerald discovers that even in cranky moments, she is safe, normal, and deeply loved.
