Zero No Tsukaima Prequel

Anyone know much about it? I found it by accident while in China and am now in the process of reading it.

 Spoiler

All I've got is this is about Louise's mom, at least that's what I think from the cover. I would really love if I can get the Japanese names cause the Chinese ones are a pain to translate.

If you're wondering what it's about, all I can offer is a quick/easy translation:

Jia Li Nu is a girl who hates to lose. She still remembers the Knight that saved her when she was little. In order to join the no Women allowed Magical Defense Squad, she disguises herself as a man, and changes her name to Jia Ling and heads towards the palace. Little did she know, she was already falling into the plot of Sai Dou Li An. Jia Ling was given to that cold and distant man, Sai Dou Li An, how can she return home like this? She came to become a knight in the Magical Defense Squad, but instead she was put into the care of the hated Sai Dou Li An, she also has to live with him! Will she be able to hide her true identity as well as become a Knight? The dangerous yet beautiful cross dressing girl's story begins now.
