The Dragon Prophecy

I, Geronimo Stilton, was astonished to find myself in the Kingdom of Fantasy for the fourth time. Sterling, the Princess of the Silver Dragons, needed my help! An ancient prophecy said that a Knight would save all the dragons... and it looked like I might be that Knight. The last existing dragon egg had been stolen from Sterling. If that egg was destroyed, dragons would become extinct forever! I couldn't let that happen. So my friends and I set out across enchanted lands to defy dangers and restore peace to the Kingdom of Fantasy!
