I have enjoyed all (but the very last) of the Iron Druid Chronicles, so I was excited to be introduced to a new character and aspect of this world. Sigils were fun but may have made life a little too easy in places which took some of the suspense out of the book. Al, the MC is an older man who is a Sigil Agent who soon after the start of the book gains an obscene, humorous hobgoblin sidekick. Al learns that his recently decreased apprentice was involved in Fae smuggling and soon goes to investigate and right any wrongs. I liked this plot line even if the ending was overly dramatic and unrealistic with the high body count usually found in action books, but it worked here. This book reads like an action, thriller kind of urban fantasy books. Lots of fighting, obscene humor and while it was not my favorite, I was greatly appreciative that it was done without being homophobic, xenophobic or misogynistic. This might be the best I have even seen that balance achieved. My main issue and why it dropped to 3 stars was because of the human smuggling subplot and how forced it felt to the overall plot. I agree completely with the author’s feelings and explanations but the long info dumps took one out of the book and made me want to skim them. It also felt forced and very unrealistic with the relationship with the police. There would have been ways to comment on parallels to human smuggling without just having Al lecture. I am not sure if I will return for the second, but I recommend it to anyone who likes humor and action adventures and is tired of having to deal with problematic protagonists to do so.
