More than 18 million Geronimo Stilton books in print! Finally, I was about to leave for a relaxing vacation all by myself. I was ready to kick back and connect with nature. But somehow, my peaceful trip turned into a crazy treasure hunt in the beautiful Black Hills of South Dakota with the entire Stilton clan in tow! Our journey even included a hot-air balloon ride to Mount Rushmore. Holey cheese! This was one adventure I'd truly remember. Geronimo...

Geronimo Stilton has to deal with his worst enemies, the pirate cats who have learned to travel back in time to Paris, France. They have a plan to thwart the dedication of the Eiffel Tower.

"Japan, 1603, Geronimo and his friends don't know why the pirate cats went back to this precise point in time, but they are sure the pirate cats are up to no good! Posing as a traveling troupe of actors, Geronimo somehow manages to convince the locals that he's really a shogun, and not the first samurai! Will Geronimo be able to uncover the pirate cat's plan in time to stop them? Or have the pirate cats finally won?"--From the publisher.
