Mopsy Capitolina, the best jeweler in the Beautiful Valley, went into the library where her sister Fenya was writing another book. Capa saw a box with an amazingly beautiful crystal on the table and couldn’t believe her eyes! It was a wonderful Mayurmi stone! Tales and legends of the Beautiful Valley tell about him. When Fenya left the library, Capitolina took the stone to take a better look, and then... the bird Envious Eyes flew in and stole the crystal. Now Kapa and her friends must find and return the Mayurmi stone at all costs. Oh, what a difficult task it turned out to be! Capitolina and all her companions had to look for answers to difficult questions. How to overcome envy? Can you judge a cat by its clothes? Is it better to lose or win a competition? And who should Mayurmi ultimately belong to? Who is worthy of owning a stone that will never want to help someone who has envy in their soul?! The publishing design is preserved in PDF A4 format.
