I couldn't believe it. I, Geronimo Stilton, had to travel back in time to save a friend Professor Paws von Volt needed my help. He had traveled to the past alone to prove that an artifact in the Egyptian Mouseum was genuine -- and now he was lost in time



My friends and I boarded the professor's newest time machine to go find him, and ended up on a crazy trip through history. We met Cleopatra, Genghis Khan, famouse poet Dante, Queen Elizabeth I, and more. It was a fabumouse journey But could we find the professor and make it back to the present?
