The story of Ruffen has everything it takes to make a good children's book: a hero for all readers to love, struggles we can all identify with, an exciting and dramatic plot, great illustrations with lots of funny detalis - and a happy ending!
The book har sold more than 40 000 copies and was Tor Åge Bringsværd's breakthrough as a children's author as well as Thore Hansen's breakthrough as an illustrator of children's books.
Three of the Ruffen books are also avilable as apps, read by Trond Brænne.
Ruffen turned 40 in 2012. This anniversary was celebrated by republishing the very first Ruffen picture book exactly as it looked in 1972, for the benefit of old and new readers.
