One word sums up this book: Magical. The atmosphere of this story is well researched and crafted. This book does not feel like a debut's sequel and yet it is. The imagery is absolutely stunning. I feel as though I am being transported to Russia and it is breath taking. The story reminds me of the fantasy novels written back in the 90's and that is a huge compliment as those were amazing. I am constantly looking for atmospheric fantasy stories that have quality world building and this series has it. I heave read that the author has done a great deal of research on Russian mythology for this novel and it shows. The background information and world building seem feel described and thought out. I will definitely be reading this series.
