The Serpent and the Wings of Night

I give this book a 4 stars rating. The ending completely changed everything for me. At first I thought it was 3.5 stars but the last two chapters were amazing and completely unexpected.
The characters had incredible chemistry but they do felt a tiny bit flat because there were so many mysterious personalities, although I guess it was understandable because of the context of the story.
I do think the pacing is a bit slow in the first half of the book but the second one flows much more smoothly and again, THAT ENDING.
