The characters are clearly delineated and the other story grabbed me. I want to know what happened to the little boy and the merchant, not just Joost and the girl, Anya. What are the grisha and why are they such valuable apprentices?
The inside cover shows pictures of the books in the author's Grisha Trilogy. I recognized one, Shadow and Bone. I'd picked it up at Comic-Con and I'm going to read it next.
