Liza is already 14 years old. A magical gift, a title, studies are not an easy burden, and then there is jealousy of Margot, Ingo’s fiancée. Suddenly, Lisa and Ingo’s grandmother is struck down by a mysterious disease, which even the magicians from the Magic University, where Ingo studies, are powerless to cure. Only an apple from the magic Garden can save grandma, but no one knows how to get there. Ingo is torn to pieces: the terrible legacy of the sorcerer Mutabor also falls on his shoulders. The animate Black Castle, where Ingo was once captive, was left without an owner, is looking for a new master: moving between different worlds, he crushes everything in his path and threatens the entire universe.
