Amazing! 
 Okay, saying amazing it how I mildly felt about it. After finally digesting a majority of the plot, twists and turns Maas has launched at me, I'm finally sorta ready to give my full review of this book. 
 First off, Maas has gotten immensely better at writing. How do I know? I usually take time to read beginning of fantasy books - even her initial 3 because it's a little slow to me. However, this 4th one had me hooked from page 1. Even with exams looming around the corner, I still sought out time to read/listen (while walking around) to this book because I just simply couldn't wait to find out what happens next. And of course, the plot twists in this book got me going just slightly crazy - ranting to my best friend (who have read this book) and my boyfriend (who just reads cookbooks) about how my heart cannot take any more of this YET I still wanted more. I couldn't stop myself. I just had to know what happens. 
 Some of the highlights of this book for me was the background of some of the minor characters from previous books like Lysandra. And the introduction of Elide, learning more about the witches and not just Manon was great. I loved reading their sections and anticipated them. Also Kaltain's appearance in this book made me like her as well. surprising! 
 However I wasn't too happy initially with Aelin and Rowan's relationship. I understand how and why they would eventually get together but I loved their relationship before. They eventually grew onto me though.
