Geronimo Stilton: Back in Time Series

Sabi absolutely loved the Geronimo Stilton science-fiction series, which features Geronimo and his friends time-traveling to different historical eras. The catchphrases in these books, such as “Mouldy Mozzarella,” “Great Cheese Balls,” or “I’m quaking in my paws,” particularly amused her. This series also introduced her to history.
