"For the first time, my uncle poisoned me when I was seven ..." Jovan externally looks like a quiet, unobtrusive young man who differs from others only with a lifelong friendship with the Chancellor's charming, reckless successor. In fact, however, he is a master of poisons and herbs, a trained tasting, who has the task of protecting the ruling family. Even his sister Kalina behind the mask of balance and peace hides a life full of lies and secrets - some of which do not know even Jovan himself. When the Chancellor unexpectedly succumbs to the unknown poison and the capital finds himself in siege, Jovan and Kalina must pull into the fight against the unknown enemy and save not only the successor, but also the whole city and the country. Gradually, however, they find that the society in which they were born and in which they grew up has two faces and, besides beauty and civilization, there is also tyranny and betrayal. Danger lurking at every step, and the ancient ghosts of the country are awakening… and they are very angry.
