Welcome to Brünnburg, the prestigious lyceum for aspiring magicians. Jošt Vaněvski, the son of the heroes of the Great War, joins it. But the more famous his parents are, the more invisible Jošt tries to be. He has no desire to become a great magician, he doubts his abilities and he doesn't want to go to Brünnburg.
But he soon makes friends in a castle full of intricate corridors, ghosts and strange artefacts - his classmate Bruno and his cousin Rézi. And also the ghost of Marcel, who teaches him to master spells that freshmen don't normally learn. But why did the former sorcerer choose Jost? And are his intentions really as pure as they appear?
Meanwhile, emerald jewels mysteriously disappear from an antique shop in Ehzeln. What at first seems like a series of strange robberies turns into a complex crime, and the chief magician, Jošt's father Alexei, is brought in to investigate. The trail reveals ancient wrongs and, to Alexei's dismay, leads to Brünnburg.

Anna Kouřilová was born in Brno, but spent most of her life in a picturesque South Moravian village, among fields, forests and vineyards. She inherited her passion for writing and her typewriter from her grandmother, to whom she dictated her first stories before she could read. In high school, she was more interested in science than literature - yet she managed to write and direct two plays, read most of the "fantasy" section of the local library, and entertain her classmates with her own stories. During her studies at the Brno Medical Faculty she started to earn extra money as a medical copywriter and after finishing her education during her maternity leave she wrote her first book. She now works as a GP and, apart from writing, enjoys amateur theatre, scouting and collecting and reading comics. In her texts she likes to be inspired by the works of T. Pratchett or A. Sapkowski. Her favourite book is Inkheart by C. Funke.
Jiří Kouřil was born in 1997 in Kyjov and spent his youth in the undergrowth of a fairy-tale castle, where a dragon, a black priest in a chariot or a film crew sometimes passed through. To escape this idyll, he went to study in the realm of absurdity, cynicism and ambiguity called Brno. There he translated his love of maps into the study of geography and later agroecology. He liked to consume stories (whether in the form of books, films or comics) from an early age, but over time he discovered that the most interesting ones are hidden in history - whether human or natural. That's why he tries to make his stories grow out of a believable world. After all, Knaak and Sapkowski were the literary fathers. In the wild, he is most often seen droning over the fields of Haná, gazing at dark corners as if cut out of Mike Mignola's drawings and drooling at the premiere of Wes Anderson's latest film.
