Ever since Kaya realised that she carries the magical heritage of the Avanosts and can transform into a bird at any time, her life has changed completely. Kaya has taken on a great task: following the rules that were once laid down for all Avanosts, and kept in the Chronicles, she intends to have at least one child from every Avanost tribe join forces, and to overthrow the power-hungry leader Xaver Goldeneagle. But how are Kaya and her friend Milan supposed to track down these children? After all, the Avanosts live in complete secrecy. Then Kaya hears about a singing competition between all the schools in the city. Kaya and Milan are certain that they will find other Avanost children there, as Avanosts have as a rule beautiful singing voices. But they haven't reckoned with Xaver Steinadler, who is determined to stop Kaya.
A mysterious prophecy, magical feathers and a group of children who fearlessly stand up for what is good.
