Loved the world, its history, its magic, the characters and the plot.

Didn't like the pacing. The book was too long, there were too many flashbacks that didn't contribute to the story and because of the different POVs plus flashbacks, I couldn't really get a feel for the characters and relate to them, so at the end, I was pretty much not interested in anyone anymore.
I feel this could have benefited from being separated into two books - one containing the main story and a second one with all the background story.
