Golden cage, or a true story about the Princess of Blood

A spoiled princess dreams of a bird with which you can talk. She does not spare anything and nobody, achieving the fulfillment of this impossible desire, and ceases to pursue her dream, only having received a promise from one person. A promise in the form of a bird egg. In the luxurious illustrations of Karl Knu, beauty is reflected, vitality and possibilities to which the main character remains, apparently, blind.
