Lady of Sh'iao Kuo warrior of the South 

by Laurence Yep

My book was about a savage princess in ancient china who got sent to school in a Chinese town. 

She never new that she was going to use her skills to help her father and brother with a war. many people she new died from the enemies they faced. She ended up marrying the person she wanted and became a well non person through the land. This book is from the royal diaries and is pretty good if you like war and Chinese things.
