Query: Overly Complex, Flat Characters

I'm usually very selective with what I read, so it is very rare for me to leave a book unfinished. Sadly, that was the case for The Darkness That Comes Before. This is clearly a very ambitious book, but the author over-emphasis in ultra-complex world-building at the cost of character development left completely uninterested in the story.
