When Oona and Eeli's class gets a substitute teacher, strange things start to happen at school: the students become obedient, and at the same time get all excited about playing the recorder. Meanwhile, a strange series of factory fires keep policeman Dad Man busy, who, as usual, is vigorously chasing a false lead.

The appearance of the new teacher at the crime scenes makes Oona suspicious. Even the adults start to become obedient as the weird flute playing trend is spreading like wildfire and this time Eeli is of no help to Oona. Will Oona succeed on her own in stopping the substitute teacher from taking over the world?

Dad Man and the Horrible Hypnosis is a hilariously joyful work. There’s imaginative humour in the wild recklessness of the plot and the characters’ acts and mistakes. [--] Vaalio’s illustrations are also thrillingly full of expressions and instantly joyful. Some images also have so many small entertaining details that even if one spent minutes and minutes examining them, there’s always something new and fun to be discovered.

About author

Arttu Unkari

Arttu Unkari is a teacher from Helsinki and a Master of Education (University of Helsinki, 2015) who majored in ethics and philosophy.  He combines his educational background and experience as a teacher in his books – his stories are anarchist and zany, but at the same time the humour often revolves around profound and intriguing concepts such as honesty, obedience, and morality in ways that speak to children in their own language. His books are enjoyed by adults as well because they contain layers that open up differently to readers of all ages. This is one of the reasons Dad Man is such a great series for the whole family.

As an author Unkari is a Runeberg prize nominee 2023 for the third instalment of the Dadman series: Dad Man and the Horrible Hypnosis (Isämies ja hyytävä hypnoosi, Otava 2022). The Runeberg Prize is a literary prize awarded by the newspaper Uusimaa, the City of Porvoo, the Finnish Writers' Union, the Finnish Critics' Association and the Finland’s-Swedish Writer’s Association. The prize was established in 1986 and it is awarded annually in Porvoo on 5th February, the day when Finland celebrates their national poet Johan Ludvig Runeberg. Three of his books (Dad Man and the Exploding poop, Dad Man and the Evil Little Brother, and Dad Man and the Horrible Hypnosis) have been nominated for best children’s audiobook in the 2020, 2021, and 2023 Finnish Storytel awards. He’s also participated in making a Finnish language schoolbook (Loikka 3, Otava 2022).

Unkari is a sought after inspirational speaker in his home country. He’s visited schools all over Finland advocating for the importance of reading.
