Heine Wittgenstein has accepted the position as royal tutor to the four young princes of Granzreich. It's a challenge as he must get the princes to accept him as a tutor.
This first volume of the series seems to mainly be introductions to the five main characters. Each prince is completely different in their personality. The only real mystery is the main character of Heine. I'm definitely going to read further into the series to see how the story develops.
