I've been doing nothing but talk about this series for the last two weeks and I'm all talked out. 
 But I will say that all in all I liked this final installment even if it was a bit predictable and I felt that Feyre and Rhysand's relationship grew a little boring. I think I would have preferred if they only really got together in this last book. 
 I'm also not too happy with some of the things that probably will be part of the future books. (view spoiler)[ I don't like what Mor hid all her life, not because of the thing she hid but because she did so much damage while keeping it secret. I also hate everything having to do with Elain and I will never stop raging if either Az or Lucien will end up with her). The only thing I'm REALLY looking forward to is hopefully a lot of Cassian and Nesta (hide spoiler)] 
 All in all no match to ACOMAF and a bit too heavy handed with trying to make readers curious about the next books but still enjoyable for the most part.
