Who's Henrika in the novel Confessions of an Ugly Stepsister?

Henrika, Clara's mother, was like a bee hurrying about her affairs. She bossed her husband around and lived every moment for her daughter, Clara. She was never more than one room away from the girl. Henrika forbade Clara to go outside since her kidnapping incident. When Henrika learns she is pregnant, she hires Margarethe to stay in her house. The two women bicker over child rearing techniques because Clara is obviously spoiled, but Margarethe pushes the limits because she knows the van den Meers need her. Henrika has a difficult pregnancy and dies mysteriously several months before she is due.
