Katarina Ma Xiu Ying
Katarina is the second of Sergei‘s children and Lady Ma‘s grandchildren. She holds her grandmother in the highest regard, and because of this, she knows she can get away with being headstrong. She is forthright when expressing her opinions, which her grandmother quietly encourages, although in public and while the family are entertaining, tradition demands that she be demure.
Her cousin Nina is her best friend, and they confide in each other about everything. When they are together and Sergei is at home, he quickly becomes exasperated because of all the giggling.
