author does a marvelous job with the driving development of the story while not keeping it stale and has a superb magical system while complex can still be digestible
the story is very fluid and I like the progression of the witch union and the island witches. I really look forward to seeing how they handle the church and the devils
the story has an interesting premise and the applications of witches to further technology is both a funny and interesting concept. the Romance between the characters is interesting and doesn't feel forced.
