Amaryllis in Blueberry

I read Amaryllis in Blueberry because my mom's book club read it. The title is attractive with neatly arranged tongue whipping syllables and blue petals slipping through folded fingers cupping a blue flower with a fading blue dress as the background. It begins with the end. I know the mother is on trial in Africa. I know she feels unfairly tried because she has no due process of law. I know she acknowledges her racism towards thinking she and her white family were above the law because they were white in black Africa. I know she committed murder and committed adultery. I am assuming she killed her husband but I don't know that for sure. I do know that Dick ,her husband is dead. He was murdered with a bullet, or is it a poison arrow? But that everything would be so spelled out seems a little suspicious to me. She never specifically says, I did it. She is annoyed by him and he haunts her but I really do not think Dick is the one she murdered. She could have murdered her secret lover. She could have killed anyone who knew about her affair. I think her husband was killed by someone else; she is on trial for it or maybe not for his; she killed someone but not him.
      And then you learn about the family's life in America, vacationing in Michigan. You learn about the four Marys. The fourth, Amaryllis, is obviously not the daughter of Dick. She has dark skin contrasting to the blonde Marys. Amaryllis has powers to sense emotions and feelings around her. Amaryllis in Blueberry has an interesting description of powers like hers. While most stories of sensing the supernatural involves a colored outline, Amaryllis picks up emotions differently. She smells feelings, can see them like waves, can see colors. It is a very interesting book, but the author makes quite a few unnecessary jabs towards Catholics; and being a strong Catholic--although I know it is good to be exposed to opposing viewpoints-- I don't think I will continue reading because I don't want my faith tainted,and also I don't like reading negative and actually misinterpreted Catholic comments.
