My immediate reaction : ok but like, where is Trin ? 
 I had a good time reading this book, especially during the second half. I was a bit bored during the first part that was basically a fight scene after another, not really mixed with anything else interesting. But then it got much better. I really liked this storyline and what happens to the characters but it didn't make much sense with the first 2 books? Like, why would Trin just press pause on her plans like that? Also, as more characters get introduced it feels like the author is spending less and less time developing them. I wish we could have had more time with Darri and Talia (and what's up with her and Brasti?!) 
 However I did enjoy my read a lot and also... Last But certainly not least. 
 BRASTI. 
 He has certainly become one of my favorite characters of all time. He is too precious for this world, I cannot deal. There's one scene especially toward the end of the book that broke me. De Castell really better not kill him in the 4th book, I'll flip tables.
