I picked this series up when I was incredibly frustrated at my inability to find fiction that kept my attention.
This kept my attention- I read most of it in one sitting, and had to be yelled at to go to sleep.
The bit where the character is telling you the story isn't abused-- normally that kind of thing feels like a gimmick and throws me out of the book, but here it added to the character, and really managed to convey the two-souled business going on with Yeine and Efna
at the end really well.
Also, this wasn't FUNNY FUNNY ALL THE TIME, but it also wasn't GRIMDARK ONLY YOU CAN SAVE THE WORLD. Nice tonal balance.
The world building felt like some real old school sci-fi/fantasy stuff, "it isn't incest if you're GODS" included. :) Loved Yeine as a POV character, she was great.
