About the book: year / My name is Katerina, and having died, I woke up in another world, and even in a fatter body. I was mistaken for some Marquise Catherine, and I had to become one in order to survive. This world is strange and cruel, and my stepmother also sent me to study at a military magic academy. Only at the academy my life was not like sugar. A faculty where mostly boys study, magic that I could only read about before, and an arrogant duke who wanted me to become his slave. But the girls from Earth don't give up! We will master magic, we will put the Duke in his place and we will definitely lose weight! Something just went wrong. I lost weight, found out that I had the magic of life, fell in love with the Duke, and it was all the emperor’s fault. Why? Let's ask him!
