The Disappearance of the Royal Ring

A ring with an emerald — a symbol of the ruler of Eiland, Rusin — has disappeared from the palace treasury. 

And just a few days later, Prince Georg from the neighboring state will arrive to ask for the hand of the monarch's eldest daughter, Petra. 

If the ring is not found in Rusin, he will lose the trust of the peoples of the Union of Southern Kingdoms... 

The younger sister of Petra, Lada, decides to find the treasure before the high guests arrive, and she will be assisted by the gardener's son, Nils, who was unjustly accused of stealing the precious relic...
