Question: who is mevrou in power of one?
Answer: Mevrou. At Peekay's first school, the first example of adult cruelty he ever meets comes in the form of Mevrou, Afrikaans for Mrs. or Madame. She's terrifying, but does have her soft spots, like when she hires Granpa Chook to kill insects in her kitchen instead of chopping his head off and having him for dinner.
