Stormhaven by Jordan L. Hawk
This one was the most angsty/ feelings filled one and I LOVED IT.
There was the usual mystery to solve with the amazing Christine to help (whom I love, by the way because she's amazing and she's a complete badass) but i also loved that there was more to the story.
A lot of feelings and trouble they had to fix as a couple. I felt like there was character development and that makes me want to keep reading the story to know what else is coming their way. I liked it.
