The first two-thirds of this were very slow for me and I don't know why - this book is all my favourite characters from the Shadow and Bone trilogy so I should've loved it but I don't know, it just felt boring to me. And don't get me wrong I love Nina more than anything but I don't know what the point of her storyline was, it felt so separate from the main plot (although I'm sure it becomes more connected in Rule of Wolves). Negatively aside though, I LOVED the last third of this book. The whole section with Nikolai and Zoya in the Underworld was amazing i loved it so much. and the twist of Brum still being alive????? oooo my girl better get him fr in the next book, I CAN'T STAND that man. The last section really saved the book for me!
