Charlie and the Chocolate Factory by Roald Dahl

Charlie Bucket, a poor boy with a kind heart, wins a golden ticket to tour the mysterious chocolate factory owned by the eccentric Willy Wonka. Alongside four other children, he enters a magical world filled with rivers of chocolate, nut-sorting squirrels, and fantastical inventions. One by one, the other kids are eliminated due to their bad behavior, leaving Charlie as the last child standing. As a reward for his honesty and humility, Wonka offers him the factory itself. The story is a deliciously strange adventure with a strong moral core.
