Geronimo Stilton 18: First to the Last Place on Earth by Geronimo Stilton
It's a race to the bottom of the world when Geronimo and his friends Petunia, Benjamin, Trap, and Bruce join explorer Roald Amundsen's expedition to reach the South Pole in 1911. From Norway, through Portugal, and then straight on to the Bay of Whales in Antarctica. They'll have to evade the sneaky sabotage of the Pirate Cats to make sure Amundsen is the very first person to reach the Pole!
