DAD MAN Series Celebrates 300,000 Copies Sold!

We are thrilled to celebrate that the wildly laugh-out-loud DAD MAN series, written by Arttu Unkari and illustrated by Kai Vaalio, has sold 300,000 copies in Finland. Book #7 in the series will be published this Spring – stay tuned!

Dad Man is a dad to a nine-year-old daughter Oona, and a policeman who think he knows everything, but the reality is different. Oona and her friends follow her dad and helps him secretly to solve all of the issues herself. The series offers a fast-paced adventures and humor for all ages, especially lower middle grade. Bold and fresh 4-colour comic-style artwork adds visual jokes to the narration. A perfect “gateway series to literature” for reluctant readers and for fans of David Walliams and Captain Underpants.

It’s rare to come across a humorous book that also manages to maintain gripping suspense right until the very end, topped off with a surprisingly complex plot. The crime is given several plausible suspects, and alongside all the laughter the reader finds themselves biting their nails while trying to untangle the intricate mystery. [–] This book is pure genius!”
Lastenkirjat.net on book #6 Dad Man and the Mysterious Puppet Master

A funny and engaging series [–] The series has such delightful characters, carefree school anarchy, and flight of imagination, and one is looking forward to the continuation.”
–Ilkka Valpasvuo on Kulttuuritoimitus magazine

“The duo smartly combines the narrative styles of comics and prose. Vaalio’s illustrations offer many visual jokes and almost accidentally urges one to read Unkari’s story.”
– Savon Sanomat newspaper

The rights are still available in Norway, Slovakia, US/UK, Türkiye, Spain…

Dad Man is a dad, and a policeman – but he also has a superpower! Too bad his superpower is one shared by almost all dads – an unwavering belief in himself and his own abilities. Dad Man truly believes he knows everything and can do anything, but as it goes with most dads, the reality is quite different.

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 Dad Man 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.  All of his previous books (Dad Man and the Exploding poop, Dad Man and the Evil Little Brother, Dad Man and the Horrible Hypnosis and Dad Man and the Impossible Time Warp) have been nominated for best children’s audiobook in the 2020, 2021, 2022 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.
