Mother of Death and Dawn

This was a great finale for the trilogy, with a lot of surprising moments and unexpected events, which left me surprised.

I hate the covers and think they poorly represent the story, besides turning away potencial readers (the girl in the cover isn't even remotely similar to the way she is described in the book, which makes me think:
(1) who designed didn't read the books,
(2) who edited didn't care about that issue,
(3) why does the author accepts this? The FMC has two different skin tones and two different hair colors! Isn't that a lot more interesting that the typical seductive blond?
