Another delightful story from the author of Heidi. The book follows life of a young boy Moni who looks after all the goats belonging to the people of a small Swiss village. He loves to sing, yodel, and whistle while playing with his goats. One day Moni's best friend Maeggerli reveals a dark secret and asks Moni not to tell anyone. This puts Moni himself into a fairly difficult situation. Will he keep his friend's secret?
