The Adventures of Peter Wheat #1

Peter Wheat and his mother, the Queen, must defend their tiny kingdom from the fierce Hornet Knights, who plan to burn the wheat fields. After Peter is captured by the enemy and locked in a dungeon, he escapes through a small window and crawls through underground passages to reach the mole, who helps him find a secret route to the wheat field. Peter successfully warns the villagers of the hornet invasion, allowing them to prepare their defense before the enemy can execute their destructive plan.
