The war with demons is over. For the Ronn Academy of Magic, peace means the exchange of students, the renaming of the department of demonobors into the department of demonology and a completely new life for magicians accustomed to fighting. And Jen Yarborro, the only daughter of the head of the action guild, a princess and a very wayward person, becomes a first-year student! She has in her comrades-in-arms - a poisonous possum and magic daggers, from the first weeks of study - many adventures, dad is furious, teachers threaten with a punishment cell... And then there are strange witchcraft flowers donated by the prince of demons.
