All her life, Vasilisa dreamed of protecting people from evil spirits. To become a Raven and fight in the Volsky Guard. For that, she even ran away from home and begged to become a student of the strongest sorcerer, Beremir, who had stepped away from his duties and settled on the outskirts of the Volsky Kingdom. But training was not meant to be completed. Beremir was brutally murdered, people disappear across the whole country, and the evil spirits go mad. Vasilisa goes to the capital to serve in the Guard, to figure out what’s happening, and to avenge her mentor’s death.
