Jack Nin was a poor kid who had lost his father. His mother was taking care of him and his other brothers. Since Jack's family owned a market, that was the only way they could get money. They had a lot of trouble getting money, so Jack tried to run after a ship that was going to the South Pole.
Hey, wait up!
When Jack tried to catch up to the ship, he accidentally fell into the water. While he was drowning, someone helped him up onto the ship.
Help! Help me!
While on the ship, Jack met a dog named Ranger, who was owned by two kids named Luke and Sadie. Jack and Ranger became best friends.
During the journey, Jack, Ranger, and the other shipmates faced a lot of storms and trouble in the South Pole.
Because Jack was an awesome worker on the ship, the captain awarded him with a lot of money.
