Things aren’t quite right at Copernicus Middle School when substitute history teacher Mr. Green enters the picture. He knows a little too much about ancient Egypt. Equally puzzling is the new student, Molly Stone, another expert on Egyptian history. Meanwhile, earthquakes and volcanoes are violently shaking the planet. Could these strange events be linked– and possibly to an ancient Egyptian prophecy? Dr. I.N. Stein calls on the Kid Squad to find out. Pi, Athena, Gadget, and Tank – along with Athena's cat D-Day and their new friend Molly – are on a mission to save the planet! Calico Chapter Books is an imprint of Magic Wagon, a division of ABDO.
