There wasn't any kind of real plot!
It just seemed... off. I mean, it's kind of neat to see the characters and see how they're coping after the war because they all have obvious trauma- except maybe not Amren, although she is having to readjust to life.
The book was almost pointless because the only thing that came out different then when it started was the fact that Feyre and Rhys got an estate, which is cool, I guess, but it was introduced right at the end of the book. I would have rather read a story that started a Starfall (or whatever it's called I can't quite remember) where Rhys gets the estate and have the book follow the process of them building the house. Maas could still have easily fitted everything she wanted into ACOFAS into this plot.
This book just slightly disappointed me because of the low action and I expected more from it, although I DID still enjoy the time I had reading this book
