Frankly, I don't remember much of this book because I was able to move right on to reading the third and final book in the series. I remember it was about the journey - so very definitely NOT a hero's journey - to the edge of the world, and I know it ended disappointingly. For the participants as well as for the reader, in that as usual this is revenge fantasy so no one is happy-go-lucky and no one gets what they want. Everyone ends up being unhappy, and in some cases it's even worse than that.
I'll leave my major complaints for the final book (already finished but I need to corral my thoughts).
