Aerin is the only and legitimate daughter of the king. But she will not inherit the throne, because everyone considered her mother a witch who came from the North. The north, where evil dwells, where people live side by side with non-humans, is a long-time enemy of the kingdom. Aerin lives in the royal castle, but never fell in love with feasts and balls. She found something she liked that even experienced warriors couldn’t do: she learned to slay dragons alone. And she also has Thor. They had been friends since childhood and always trusted each other. But lately something more than just friendship has begun to grow between them. And no one - neither Aerin herself, nor Thor, much less the arrogant courtiers who always disliked the witch’s daughter - realizes that the fate of the kingdom depends on her...< /p>
