Eleven-year-old Kašpar hates adventures - they are dangerous, unpredictable and disrupt his carefully worked out schedule. When he accidentally finds himself in the Uncharted Kingdom of Stargazer, he wants to return home immediately. But the Morga harpies threaten not only Hvězdidar, but also Kaspar's home, so he has no choice but to set out with Pure Ungrateful to go after goblins, snow trolls and giant hulks... and discover that adventure can really change a person.
