I'm going to keep it simple: 
 (Spoilers ahead) 
 1) I LOVE CAL. And I love Cal and Mare and the ending of this book broke my heart. I don't know who is right or who is wrong, and it feels like a break up, a very bad one, and I'm stuck in the middle between duty, destiny and rightness. 
 2) I didn't like Maven neither in Red Queen nor Glass Sword, however, I was surprised by Aveyard with a very different Maven. In Red Queen we've seen him as the shadow of Cal, the shadow of his mother in Glass Sword and now here... we have Maven, finally, without mommy around and so alone. I loved his development, how he has accepted his destiny. 
 3) Who else hopes, like Cal, to find a newblood to change Maven's mind and make him good? 
 4) I liked Nanabel, a lot, she was a pleasant surprise. Though I don't like her political schemes of Tiberious the seventh. 
 5) I am still trying to figure Iris of Lakelanders and her role in the next book. Is she good or is she just another Silver princess? She seems good but you never know in the Silver court. I want to know how the death of her father affected her, or her mother ruling over the Lakelanders or even better, did she DO it with Maven? Will we have a mini-Maven baby? 
 6) Mare is more present in this book than in the second, she is worried and she wants to survive, yet she accepts love and family and reconciles a bit with herself. C'mon how cute and sexy were the scenes between her and Cal? Making me swoon all over a thunderstorm and a prince without bracelents. And that lighting and fire fight, damn they go hard on each other. 
 7) I liked a bit more Farley in this book, maybe is maternity, so yes, the awnser to the question is yes. 
 8) Evangeline was a nice surprise. I liked her point of view, even as scarce as it was. It was nice to see her POV. Can't believe she calls Ptolomeus Tolly and he calls her Evie. That made me so happy, don't know why. Also the fact that she is the lover of Elane. It's a weird love triangle, but I'm glad for it. I can see more about the politics and the schemes of the Silver court. 
 9) Who else was hoping that Morrey and Cal would become best friends when Cameron and Mare left them alone. They share a lot of views. I still hope they become BFF. 
 10) Can't wait for the next and last book. I know it will wreck my soul. 
 "Choose me" how can this two words break my heart?
