Caderno de Memórias de Difícil Acesso it's the name Santiago gives to his secret journal. Forbidden to read! Santiago is an 11-year-old like the others. He likes to play game console and it doesn't like that much to go to school. The good part of going there is that ut's at school that he meets his friends and, of course... also Alice, the most beautiful girl in the universe.
The bad side is that other people also study there... like is older (and annoying!) sister, Mafalda. She is so well behaved and always have straight A's. She does everything well, even play soccer! Mas the worst of all is Norberto, the school bully, who likes to frighten young kids in the toillet. At the begining of the third period, a new kid arrives to Santiago's class. He looks a bit creepy and likes that people call him Frankenstein...
And Santiago writes all this down in the cool journal that his aunt gave him. He also keeps note of all his sister misdeeds, so he can plan revenge...
IT IS FORBIDDEN TO READ WHAT HE WRITES AND DRAWS IN THERE. DON'T YOU DARE TO OPEN IT!
