A Day of Fallen Night

Wow, what a joy ride, and a long one at that.
I read The Roots of Chaos in chronological order of the plot, not by publication date. That being said, I might come back to edit this review after reading #1.
Approximately the first third of the book is filled with world building and setting the plot. After that, it felt like a plateau of mostly action packed and high-stakes plot with one storyline quickly unfolding after another. While it was hard in the beginning to figure out characters and places, it is worth it:
Rich world building with lots of their own history, culture and myths/religion/cults/whatnot and great character development.
All of the 4 major characters are interesting. (I'm still puzzled about the obviously deliberate decision to not follow the story through one of the prologue babies but a different character.) The characters are of different ages and especially Tunuva in her 40? 50? was refreshing to other fantasy MCs.
Connecting the different storylines had me think of so many theories and kept me on my (mental) toes, only to surprise me and be different yet similar and I am absolutely looking forward to reading The Priory of the Orange Tree to find out how the events of A Day of Fallen Night are viewed and have implications some couple of years and centuries down the line.
