There was so much about this book that worked for me, not only the way Nik Korpon dealt with his world building, but the way his characters reacted to the world. Like all Angry Robot books, I found this a deliciously refreshing step outside of the expected, without being too off the wall and unfamiliar.
Strongly Recommend!
