Ashley Spires takes the reader through the mind of a girl who loves to tinker and build things. As she works, readers witness her perseverance, frustration, and response to failure, but also a rebound. This book presents girls in engineering and shows that yes, girls can tinker and build too, and be good at it! Educators can read this book with young and older children alike, and adjust the discussions according to their level. Further extensions from this reading can possibly go into researching female engineers.
