The Golden Key (Geronimo Stilton and the Kingdom of Fantasy #15)

Geronimo’s fifteenth adventure in the Kingdom of Fantasy! I, Geronimo Stilton, had been called to the Kingdom of Fantasy many times before. I’d visited the magical lands to ride dragons, meet fairies, and defeat evil witches. But not this time! This time, the Kingdom of Fantasy came to New Mouse City. Could I help Queen Imaginaria and put everyone back where they belong?
