Maria Engrand, who invented the trilogy about the Swedish schoolchildren who solve the riddles of the past in his native Lemu, first worked as an engineer and lawyer. But she always loved to compose stories. Over time, the hobby turned into a profession. The writer hopes that her books help adolescents see the world as exciting as he really is.

The artist Polina (Dr. Graf) Noskova created on the cover the slightly mysterious images of the main characters, which at the same time reflect the mysterious and tense atmosphere of the trilogy.
