Query: only read if you like pessamistic stories

I read fantasy to firm my faith that the world can be a better place and there can be happy endings. While Indigo does go through some personal growth, the whole series was frustrating because she repeats the same mistakes again and again, I did not feel that her personal growth was enough to make the story interesting or educational. As for the end, I hate hanging endings. I do not recommend this series at all, unless you are a pessamist.
