Like her classmates Iggy and Rosie—stars of their own New York Times bestselling picture books Iggy Peck, Architect and Rosie Revere, Engineer—Ada has always been endlessly curious. Even when her fact-finding missions and elaborate scientific experiments don’t go as planned, Ada learns the value of thinking her way through problems and continuing to stay curious.
