In the hot, dry hills of South Dakota, a tiny Field Mouse lives a peaceful existence in a burrow beneath an old, sturdy bone. That is, until his life is turned upside down by the intrusion of noisy voices, clamorous clatters, and thunderous bangs! Leaving his cozy burrow, the mouse ventures outside and discovers a strange group of people chirping, scratching, and hammering all around him. Baffled, he returns to his home, only to find that his roof — his very special bone — is gone! Determined to recover his bone, the Field Mouse sets out on a search that leads him all the way to the halls of the world-famous Field Museum in Chicago, and face-to-face with a 67-million-year-old dinosaur named Sue. The true story of the largest, most complete T. rex ever found is given a whimsical treatment in this imaginative storybook. With its breathtaking illustrations, this tale will bring the fascinating story of the dinosaur named Sue to life for children of all ages.
