The Ninja Diaries

Children's Books Comic Novels

When the adults haven’t got a clue, it’s up to the Ninja Kids to put things right!

Nick considers himself quite normal. He’s good at some things (talking, meditating, breathing in and out – he’s especially good at that!) and not so good at other things (doing maths on the blackboard, school in general). But there’s one thing he’s pretty sure about: He wasn’t born to be a ninja. But by accident – quite literally – Nick meets Master Jojo, the sensei of a secret ninja dojo. Soon, he’s not only learning awesome moves with Olga, Zoran and the other kids, but he has to save their hometown too.

Suddenly, all the power is out, and nothing is working. Could the evil geniuses Vil and Laine be behind this? Doubtlessly, the ninjas would be in a proper pickle without Nick! He really is more extraordinary than he ever imagined!

  • An exciting story full of humour and with the popular ninja theme – encourages children, reluctant readers in particular, to read
  • Saving the world made easy: Just open the book and read!
  • Previous books by the author have been translated into over 20 languages
