This is the third novel in the Cunning Man series from Butler and Ritchey. In it we have our usual spread of folk magic, mystery, ghosts and demons, and some good ol father son banter. In this novel Hiram and his son Michael travel down to Mexico and get involved in a murder mystery that may involve some dark family secrets that Hiram has been running from for a long time.
Overall this is a solid Cunning Man book, and if this is the last we see of these characters, I'll be well satisfied. I love these books, but boy are they weird. The combination of Hiram Wooly, a Mormon beet farmer, fighting off Mexican ghosts using Catholic prayers and Irish folk charms surely is self-evidently absurd. Yet it works. Michael becomes much more of a primary character in this book and becomes almost a second protagonist alongside his father. This is also the scaries of the three books by a good margin.
I would love to see more of these, but if this being the end means Ritchey writes his Christian Orcs fantasy novel and Butler keeps writing Witchy Eye books, well then I guess that's alright.
Do yourself a favor, try out book one. It's weird but you won't regret it.
