Empire of Storms is a very surprising book for me. I honestly wasn't as eager to read it after Queen of Shadows because of the events that happend previous to EoS. 
 I had a hard time getting used to the changes and different turns the series took through out Crown of Midnight and the following books. Lots of things changed in this series since I read Throne of Glass. 
 #1 Point of Views 
 Throne of Glass started of as a fantastic but very small world where you had Celaena as a protagonist and point of view during the story and Chaol and Dorian and a few more as supporting characters. But in EoS I can't shake the feeling that we entered a total different story. We have several point of views because nearly every character who is involved with the story gets his own voice. I love that. I love multiple PoVs so much but I still feel weird that this story changed so much. 
 Not necessarily in a bad way but it needs some time getting used to through Queen of Shadow were it started and now in Eos. 
 #2 Aelin doesn't feel like the protagonist 
 Actually that point is a big positive change for me. I couldn't stand Aelin in Queen of Shadows and she is still my least favourite character. I loved Celaena and even though she was only a fracture of the character that Aelin is now I still liked her way more as the badass assassin she was in the beginning. But anyway, I think in Eos Aelin gets pushed back a lot into the background because there a lots of amazing characters that shine through the story. One of them is definitely Elide. Her character stood out for me in this story. But all of the others as well. I still don't enjoy the Rowan and Aelin scences because for me there are just over the top. But other than this I loved the character and storytelling changes. 
 #3 Sex scenes / Love scenes - lots of Acomaf vibes 
 We get three very explicit scenes in Eos and it reminded me a lot of A Court of Mist and Fury. Feels like SJM really enjoyed writing sex scenes and thought to bring more into her other series as well. I don't mind at all. SJM knows how to write sex scenes. 
 This is the thing that was irritating for me though. The similarities to Acomaf really stood out. If you don't read both of her series you won't see it but Rowan and Aelin and Feyre and Rhysand relationship are very similar (up until (view spoiler)[the secret marriage (hide spoiler)]. 
 #4 Chaol 
 (view spoiler)[I'm very conflicted when it comes to Chaol. I'm not happy that he is not in this book. I'm not happy how she decided to make him into this irrelavant side character. But I also think Chaol doesn't belong to them anymore. He wouldn't fit in with this group with all their magic and crazy things that go on. Chaol belonged in a non-magic world with Celaena and he doesn't fit beside Aelin or in this world. I'm upset and I miss him as a character but I'm happy that he isn't dragged through the dirt even more by SJM. (hide spoiler)] 
 But all in all, I think Eos was 10 times better than QoS and HoF and even though the series has changed a lot since ToG I don't mind. I love the changes and I think they've been for the better. We get a bigger world, we get lots of amazing characters and twists and turns we couldn't have seen coming. I'm excited for the next book and hope to see a familiar face again because I missed him a lot throughout Eos.
