Human-loving trees we got ourselves here... loving humans for breakfast, of course, would we have it any other way?
I'm still not sure how to rate it. It's about 4,5, subjectively.
Objectively, we start at 5 stars (I read it, had no ranting fits and all...):
+1 star: my eyes got not workout here, I'm gonna pick something else to exercise them today;
-1 star: many POV's here, I sort of think there might be too many of them, and we are led from so far that I'm sure many readers are likely to get bored (not me);
+1 star: many POV's here, we are led down several roads simultaneously twisting and joining somewhere very far down the plot development, I think it's cool;
(Yes, I have contradictory feelings on the multi-POV feature.)
+1 star: very anthropologically oriented approach to world-building: I love how various societies sprout along the book;
+1 star: everything above happens without noticeable infodumping (seriously good job done featuring multiple societies having multiple quirks and all!);
-1 star: something was a bit off about the characters, some of whom were sort of larger than life (including the trees, the human-loving ones, and Faia, being sort of nonchalant on teaching her 2-year old kid to become a headhunter), though it's ok for fantasy.
