I really liked this book. The main character is a 10 year-old boy named George Calder. George Calder must be the luckiest kid alive. He and his little sister, Phoebe, are sailing with their aunt on the Titanic, the greatest ship ever built. George can't resist exploring every inch of the ship, even if he gets in trouble. Then the ship hits an iceberg and it starts to sink. George is left by himself on the sinking ship. How can he survive?
