Fantasy series: Something about fate and sagas and something

[Emma]

I found this series on Kindle like 4 years ago. It's written from different perspectives of people in different kingdoms from the north, south, east, and west, and they all don't like each other. The protagonist and antagonist are like secret princes or something, and one has life or healing powers and the other kills people. The South was in some kind of civil war and the daughters of the queen fought to the death for the throne. The south has dragons and beef with the East so the East is like completely made of iron as protection. The north has this like big giant guy in full armor and he's a love interest at some point. The Queen? or Princess? Some girl acts super righteous and like a godsend but she got pregnant by a common thief and pretended she was the next virgin Mary. Eventually some scary people, maybe dead, come from the north and all the characters have to come together and like save the world. Someone please help me I never finished it and I think about it daily.
