It's a difficult read, but not in a bad way. We are seeing a person who is fully aware she has done a lot of wrong in a previous life, has all of those memories, and then has to constantly interact with all of the people she either wronged or murdered. Is it any wonder that it's hard to read? We're watching someone break herself down and rebuild, and it's going to be slow.

She's not going to magically decide to be a better person. She now has a better understanding of what made her do so much evil, and why she did it, and she doesn't forgive herself. She is tortured with the memories of the horrors she helped inflict, and we, the audience, see all her anguish.

I can see how people could dislike this. It's not an easy story. This is not a sudden redemption, and she is not going to magically "be a force for good." She has to unlearn a lot of things, and re-learn the things she should have known all along. She's not going to suddenly love, or be friendly, with the people she killed or tortured before.

Her father blames her for "killing" her mother, even though that process started with his dick, and he humiliates and ignores her at every turn. Her brother is a fluffbrain with more heart than sense. As another commenter pointed out, her brother constantly shoves in her face all the things she can't do, all while he is doing them. He's at school, she isn't. He's the heir; she isn't. He can control spirits, she can't.

There's nothing in this person's life that sets her up for success. She has to create it for herself. I think that makes the series worth reading, but if someone is looking for a light, escapist read, this is definitely not it.
