I'm Yumi and I'm ten years old. When I grow up I am going to be the drummer in a rock band, because its a profession with a great future and I think it's how I can become rich and famous. The incredible story I'm about to tell you begins because we wanted to record a videoclip. That's when my friend, Creature, decided to become a Rockstar. Then I got into a scrape, and my father made me promise always to tell the truth, but because of that I ended up in even more scrapes. In the meantime my sister Alex and I erected a frontier in the middle of our room and neither of us could enter the other's territory. In the end we recorded that videoclip, but then a totally three-dimensional row erupted in school. The thing is, it wasn't our fault, for the record. 
A kids book with loads of illustrations in the style of "Diary of a Wimpy Kid" where, through humour, youngsters are encouraged to get into music.
