Taking the fantasy setting she created in the Shadow & Bone trilogy, the author weaves a very compelling fantasy heist filled with interesting characters with conflicting motivations. The book expands the setting the author established before while presenting a story that is more interesting than the original.

I would recommend starting with this book if not for the multiple spoilers for the original trilogy. If you don't care about spoilers, start with this book. If you do, then you should read the original Shadow & Bone trilogy first.
