Your Drop of Blood

Seven years ago, after a suppressed uprising, the prince of Belogorye, Stefan Belta, was sent to the Ostland court as a hostage to prevent his father from raising a new rebellion. In Ostland, the young prince becomes friends with the Tsarevich Lothar, who one day ascends the throne and makes Stefan his advisor. However, upon returning to his ancestral home, to the land of Bialu Guru, Stefan learns that a new uprising is being prepared against Ostland. The situation is further complicated by the fact that Stefan is a vampire and must keep his secret even from his closest ones.
