On the first day of school, Isla's mind plays the what if game. Scary thoughts come, the world goes dark, and everything feels stormy. With Mami at her side, Isla takes a deep breath and blows her worries away in a big balloon. But as school gets closer, Isla's worries come back like a tornado. Mami encourages her to imagine something happy, and Isla remembers there's nothing she can't handle. The storm might come again, but for now, her mind is quiet. In this thoughtful and reassuring picture book, Monica Mancillas's text and Betty C. Tang's illustrations show how one child experiences anxiety and worry, providing different tools to practice mindfulness and strengthen one's mental health.
