Romane Lux's catastrophic return to school

Bayard Jeubesse Editions. Children's Novel

My name is Romane!
This year, I'm going into CM1, and everything should have gone well, but...

...there is my little sister who does ABSOLUTELY everything like me,
my father who fears a nuclear attack at every street crossing,
my teacher, Mr. Boulala, who decided to bring cosmic peace to the classroom,
Kédon, the most handsome boy in the school and even in the entire Universe,
Gilberte, the most popular girl in the entire universe,
Lucie, my best friend always ready to take on any challenge.

Oh, and I almost forgot Mr. Skeleton, Mr. Boulala's best friend.

In short, it's a DISASTER!
