The fourth book in the Junior Library Guild Award Winning Series

Best sisters and big thinkers Maddie and Mabel have a new idea. A really wild idea. But can their idea become a reality? With their sweet charm and innocent curiosity, the sisters make lists, ask questions, and learn when to turn something broken into something new. Together they learn that every idea has opportunities and obstacles.

In this fourth foray, the sisters navigate tough questions and make compromises with sensitivity, acknowledging that an imperfect solution might be just the right plan. The occasional misstep and sisterly banter make this relatable and realistic for readers. The combination of Kari Allen's gentle writing and playful illustrations from Tatiana Mai-Wyss make this a winning addition to this well-loved series.
