Geronimo Stilton The Guardian of the realm (Hardcover)

Geronimo Stilton, the main character from the popular children's book series of the same name, is a mild-mannered, bookish mouse who works as a journalist and editor for The Rodent's Gazette, the most famous newspaper in New Mouse City. He's known for his love of reading, quiet life, and adventures that he often gets swept into, despite his preference for staying home with a nice book.

Geronimo is typically depicted as well-dressed, often in a green suit and tie, and is a bit on the nervous side, preferring peace over action. His sense of duty, curiosity, and a desire to help friends and family often push him into grand adventures around the world (and even beyond). He is intelligent, kind-hearted, and brave when the situation calls for it, but he’s not a natural adventurer—often finding himself scared or unsure. However, with the help of his friends and family, Geronimo always manages to find courage and solve problems with wit, teamwork, and determination.

His personality, blending intelligence, wit, and a tendency to avoid danger, contrasts with the heroic roles he sometimes ends up playing as the "guardian" of sorts, in his own unique and quirky way. While he might not fit the typical image of a bold and fierce guardian, his persistence and resourcefulness are what make him a protector of his realm in the stories.
