Geronimo Stilton : The Journey Through Time (#1) - Hardbound

I, Geronimo Stilton, never expected to set paw inside a time machine. But when Professor von Volt invited me to travel with him, I had to accept! My family came along to help us discover how the dinosaurs became extinct, how the Great Pyramid of Giza was built, and what life was like at King Arthur's court. Along the way I was chased by a Tyrannosaurus rex, almost eaten by a crocodile in the Nile, and asked to save a maiden from an evil knight's castle. Holey cheese! It was an adventure through history!
