Gwen is the daughter of a great sorceress. She herself is quite good at doing magic and is friends with the forest spirit. But one day something terrible happens - the village is captured by the Hawks, and Gwen inadvertently makes a deal with the Shadow itself. She can return the only thing that matters to Gwen if... if one condition is met. For this, Gwen sets out to meet adventures, dangers and unexpected acquaintances. The main thing is not to lose a little thing that is ordinary only at first glance - a cheap copper brooch in the shape of a seagull.
