This second and final volume of the Natty adventure picks up where it left off: Natty is alone in the underworld fighting for her survival while her family up above engages in a wild search for her. Sami manages to escape from prison, and thanks to their agility, strong will, and a dose of luck, he and Natty make their way back to the palace. After some initial difficulties, Natty is recognized by her parents as the Princess, and she and Sami live happily ever after. They even find a solution to bring sunlight to the lower levels of the kingdom.
