Ada Twist, Scientist
Ada Twist's head is full of questions. 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.
