What would happen if the whole world turned upside down? Lydia discovers that one day, as she observes her family, the neighbors, the pets and even a jet airplane, all upside down. Then suddenly we discover that Lydia has been hanging by her knees all along. In this children’s book we discover how much fun it can be to see the world from a different perspective. As Lydia observes this upside down world she playfully views all that is happening. We also discover that an upside down world can be set right again as she swings head over heels and turns the world right side up. Conceived and written by three sisters, ages 6, 8 and 9, the book offers a whimsical look at the world turned upside down.
