Grimsby, a junior Auditor in the magical Department of Unorthodox Affairs, finds himself on the other side of the law in this spellbinding urban fantasy.

Grimshaw Griswald Grimsby may have one case under his belt, but he’s still a novice Auditor in Boston’s Department of Unorthodox Affairs. And he’s already made mistakes.

Desperate to repair his fraying friendships, he doesn’t ask too many questions when a mysterious patron offers him the chance to join a heist of an otherworldly vault—and in the process find answers that could make things right. 

Complications arise when Grimsby learns that his partner, Mayflower, is keeping secrets about his past. Between facing new demons, old horrors, and monsters—both Usual and Unorthodox—Grimsby soon realizes nothing is how it appears and that not asking enough questions just might be his downfall.

ike most urban fantasy, it is important to listen to the Unorthodox Chronicles series in the order of its release. With each new installment Butcher fleshes out the world, the magic and allows his protagonist to grow. If you love urban fantasy, I highly recommend this series.

Grimshaw Griswald Grimsby is a novice auditor for Boston’s Department of Unorthodox Affairs. He worked his first case in the previous book, but still has a lot to learn. Grimsby’s mentor and partner is Mayflower, a Huntsman. I love the interactions between the two, from irritation to respect. We have watched the two form a bond as Mayflower’s reluctance gives way to friendship.

Grimsby is determined to find a cure for Rayne View Spoiler » He is also trying to help Wudge find his door. All of this is how he ends up joining a team to breach a magical vault to retrieve an item that may offer answers. In the meantime, Mayflower is trying to help a fellow Huntsman find his younger brother.

The story that unfolds was addictive and well paced with plenty of magic, demons, secrets, and twists to keep listening into the wee hours. We see shifting alliances and for me; it is the characters who truly make this world. I am hoping we see more stories in this series as Grimsby’s tale is far from over.

James Patrick Cronin narrates and gives voice to all the characters, allowing me to recognize who is speaking immediately. I love urban fantasy in the audio format, which is why despite some reservations I continued the series on audio. This review was originally posted at Caffeinated Reviewer

Thanks to Netgalley and Berkley for the pre-release copy of Cold Iron Task. Below is my honest review.

If you haven't read the famous Jim Butcher's son James' urban fantasy series, you should pick it up. This is book three in the Unorthodox Chronicles, and it's worth the read. He definitely inherited a bit of his dad's talent in regards to creativity and worldbuilding. I can see a lot of Jim's earlier books in James', and can see an upwards trajectory for his skill.

This installment shows us a new side of Grimsby's relationships - mutual trust, respect, and Grimsby truly feeling like he has friends. Mayflower's going through the wringer, and this time Grimsby gets to be true support for Mayflower, Rayne, and even Wudge.

I really enjoyed the way this one shakes out, and the amount of growth Grimsby has shown.

Definitely recommend this series for Urban Fantasy fans.

Several years ago, I read all of the Jim Butcher Dresden Files, which I really liked. I even watched all of the one season of the TV series, also good. Well, Butcher's son, James J. Butcher, has followed in his father's footsteps in writing stories stories about magic in today's world. I just finished Cold Iron Task by James. Good book, good story, which built on the groundwork laid in the first 2 books. Grimshaw Grimsby, our protagonist and newly appointed Auditor for the Department, is faced with a grim task which could affect the lives of all those he has come to love and cherish. In order to accomplish this task, he has to overcome his number one nemesis, his own lack of confidence in his abilities. Good story, many twists and turns, and more than a few surprises.

Definitely the best book from James J. Butcher yet.

This third instalment in The Unorthodox Chronicles has a good, coherent story with clearly defined character motivations and no distracting padding. There is excellent pace and consistency to the narrative, and some nice little misleads. I was a little irritated with the two main characters spending the first few chapters apart and entwined in separate story arcs, but the author pulled everything together really well further in, so all was forgiven. Unfortunately, towards the end of the book, the author squandered the big reveal of the main twist a bit.

The book isn’t flawless by any means. I still wonder if this trilogy even went through a professional editor before publication, but the very consistent flow to the book as a whole helped me forgive those irritating instances that kept popping up.

There's good and bad compared to the previous installments. The writing gets better still, characters' development too. I laughed less, but maybe it's just because the themes got darker.

I love how this series deals with mystery, and if in the previous books I sometimes found the plot twist predictable, I loved how you get to reach a realization a couple of lines before the characters do, so that their surprise and elation or dread at the discovery can flawlessly mix with your own.

An amazing job, can't wait to see what's next! 4.5/5

This book was so much fun. Cold Iron Task has everything I love in a series with great world-building, smart magic, and characters that just keep getting better.

Grimsby is an easy character to root for. He’s scrappy, clever, and dealing with so much trauma and guilt, yet he still pushes forward. This time, he finds himself caught up in a heist that could save his friend, even though his magic is still a work in progress. Watching him navigate this world with sheer determination and a little bit of luck was so satisfying. It really shows that sometimes, simple magic and quick thinking can be just as powerful as flashy spells.

And Mayflower? He’s still the grumpy veteran, but this book cracks his armor and gives us so much more depth to his character. He’s still a badass, but now he feels more layered, and I loved seeing that side of him come through. His dynamic with Grimsby remains one of my favorite parts of the series.

The world-building was spot on. I love how the magical and non-magical elements exist right alongside each other instead of being hidden away. It makes the setting feel real and lived-in. The magic system is unique, and since Grimsby is still figuring things out, there is so much potential for it to grow in future books.

This book nailed the pacing. There weren’t any slow spots, and every scene felt like it had a purpose. I flew through it and didn’t want to put it down.

Overall, Cold Iron Task delivered everything I wanted with action, heart, and just the right amount of humor. If you love urban fantasy with a unique twist and characters that make you want to cheer them on, you need to pick this up. I’m already excited for whatever comes next.

Cold Iron Task by James J. Butcher is an amazing continuation of the Unorthodox Chronicles and easily holds its own beside the earlier installments. The story remains strongly character focused, which is one of the series’ greatest strengths. I especially enjoyed the evolving relationships between Grimsby and the supporting cast. These dynamics are developed with satisfying depth and complexity.

Grimsby continues to shine as a protagonist who is genuinely good both outwardly and inwardly without ever slipping into a flat stereotype. I care about him and feel invested in the struggles he shares with his friends. I also love that the book avoids placing a love story at its core. Instead it centers on friendship and the question of what kind of person you choose to be when facing real adversity.

Another highlight is the structure of the plot. Grimsby and his partner juggle multiple cases at once, which keeps the pacing lively and makes the world feel layered and active. The writing style remains delightful with plenty of showing rather than telling, and it is still one of the things I appreciate most about the series.

I will admit I was genuinely sad when I realized the next book is not yet available. It is rare for me to find an urban fantasy I truly love since so many fall into familiar tropes or stereotypes. This one does not. Even though I would not call it a perfect book, it gets the important things right without relying on a formula. There is still room for the world to be fleshed out, but the expanded exploration of the Elsewhere in this volume was a welcome step.

The audiobook narrator, James Patrick Cronin, also deserves praise for an excellent performance.

I cannot wait for this series to continue.

I continue to have a lot of fun with The Unorthodox Chronicles. They’ve got a very classic urban fantasy feel and some neat, creative world building that is just a joy to explore. And Grimsby is such a fun character—underpowered in a way I haven’t often seen in this kind of story.

Cold Iron Task does end up feeling a bit like it’s mostly doing setup work for later books in the series. That’s not to say it isn’t fun—Grimsby’s magical heist is plenty entertaining (and continues to expand the world in interesting ways) and it’s cool to learn more about Mayflower’s history—but I definitely closed the book feeling like things were less…complete than I was expecting. Still, it’s a fun urban fantasy romp and I’m excited to see how the things set up in Cold Iron Task develop in future books.

I know I say it every time, but I'm always very impressed with James J. Butcher's strength as a writer, where he shines enough on his own to not be under his dad's shadow. You see his father's influence in his writing, but James J. undeniably has found his own style and his own voice, and his writing is distinctly different.

You know where he really shines the most? Dialog. James J. Butcher writes some of the best dialog, whether it be snark and sass, or stilted sentimentality from a gruff and reluctant old man. The sass especially. I love the sass. It never feels forced like he was just trying to find a way to fit in some clever line he thought of, it never feels fake like it was something no person would ever say in that moment. He's built characters that are quick and clever, and whos mouths run ahead of their brains, and the way they play off of each other is fabulous. I don't have my physical copy on me at the moment, only the audiobook, so my punctuation and such might be wrong, but nonetheless, some of my favorite examples include:

"You can throw fire around, can't you? Every witch I've ever seen could."
"Well I tend to catch fire more than throw it, but it's basically the same thing."


"You're sure about all this?" he finally said.
Grimsby nodded, "I saw it."
"How the hell did you see it? Security camera?"
"No, it was..." Suddenly he felt a little ridiculous. "It was in a memory?"
"A memory."
"Well, the memory was in a fox, and I touched the fox and saw it."
"You touched a memory fox."
"It was an origami fox, to be clear."
"Much clearer."


"You're a good man, Mayflower."
"What?"
"Nothing!"


Like, that last one isn't even that funny on it's own. But in the context of who the characters are and how they interact, it had me fully giggling to myself. Grimsby is so determined to be strong, and capable, and be seen as a powerful and competent auditor, and he's well on his way to being so, even if he's not taking the standard route to get there. He's a good guy with a strong moral compass, and he stands behind his convictions with confidence. Which always just makes it even funnier when he's so cowed by this old man that's his partner.

Also, damn, we got all this Mayflower backstory! Why his life gotta be so sad?! And he's not The Hunter, he's just a hunter?! I like that Mayflower is getting to a point now where he's constantly thinking "What would Grimsby do?" Not that he would ever admit that to anyone, especially not Grimsby himself. But I love that he recognizes Grimsby's strong moral compass and uses it as his own guiding light, even as he tries to maintain his curmudgeonly "I don't care about you or anyone or anything" image.

I wish they were together more in this book. They were both sort of out on their personal missions, and it made sense that they weren't really working together on them, but I like it when they work together. They're better at it together. I think they recognize that now though.

And shit, man, the whole thing with the

This review originally published in Looking For a Good Book. Rated 3.5 of 5

Grimshaw Grimsby is a junior Auditor in the magical Department of Unorthodox Affairs and Huntsman Mayflower is his mentor. Grimsby has been struggling to find his way within the department and has made more than his fair share of mistakes along the way. His gruff mentor, whom he looks up to, hasn't been as forthcoming as Grimsby has hoped. In fact, Grimsby is sure that Mayflower is holding back on something.

Mayflower leaves Grimsby alone to go to Boston to help another Huntsman - there being plenty of complications with Mayflower being in Beantown.

Grimsby is on his own then to help the imp Wudge; hoping it will result in Wudge leaving Grimsby alone (he can fail on his own without any help thank you very much). Rayne needs to be saved but the biggest issue facing the you Mr. Grimsby is the day-to-day work necessary in the department office - meaning he'll have to skirt the rules and push the boundaries of the laws to complete his other tasks.

There's plenty of action here - it's almost non-stop, keeping us turning pages rapidly. That's definitely a plus in this urban fantasy.

Because I've read the previous two books in the series it's hard to say for sure, but I would be concerned that you might need to have read the previous books in order to really understand and appreciate what's happening here.

I found Grimsby to be a character of some growth over the course of the three books int he series. Oddly (or perhaps not), the young author James J. Butcher also seems to be growing as a writer - mirroring Grimbsy's growth as an auditor.

Mayflower stands out more for me in this book. The gruff older mentor stereotype is becoming less a stereotype and more of a unique individual. His confronting of his past is helping to flesh out his character.

It's a pretty quick read, despite its page count, and for those of us who miss 'father' Butcher's Dresden series, this is becoming an acceptable stand-in.

Looking for a good book? Cold Iron Task by James J. Butcher, the third book in the Unorthodox Chronicles, is fast-paced urban fantasy with characters who are becoming much more clear and interesting.

I received a digital copy of this book from the publisher, through Netgalley, in exchange for an honest review.

It's hard to not compare James J. Butcher to his father Jim Butcher, and by writing a series about a magical law enforcement officer conspicuously operating in a major US city the younger Butcher is inviting the comparison. Indeed the superficial similarities between the Unorthodox Chronicles and the more pithily-titled Dresden Files is what made me want to read them.

The bones of both series are more or less the same, and they are both fun if you like complicated magical worlds intersecting with each other and harried, underprepared magicians doing their level best to protect the public from forces beyond their comprehension. The protagonists are quite similar as well: they are both quite lippy and tenacious, hard to kill, blessed with mysterious and powerful allies, and have a complicated relationship with their respective Organizing Bodies. One of the main differences in character is that, while Harry Dresden is very powerful and has only gotten more so as his series has progressed, the annoyingly named Grimshaw Griswold Grimsby is quite weak; while he is somewhat knowledgeable about magic he can only use a few spells with any degree of consistency, and he is also a short and scrawny 20-year-old. Dresden is a more obviously Heroic hero figure, but he has had more time to develop.

My only problem with these books so far, aside from some clunky language that could stand another pass or two (ask Dad for some help with idioms!), is how hard they are pushing their mysterious metanarrative. Grimsby has a scarred arm from a mysterious fire that imperfectly channels magic, a black-skulled revenant haunting him, a more talented friend with a curse interfering with their magic, a reluctant faerie ally who wants to return home, an invitation from the Bad Guys to swap sides, probable infiltration of the Good Guys organization, an iron knife with his name on it, and a hint that his mother was more powerful and important that he realized. And those are just what i can think of off the top of my head. That is too many hooks for three books into a story. You gotta tie some of those loops off before you add more, eventually mysteries piling atop mysteries switch from intriguing to annoying.

I will probably keep reading these if I keep seeing them show up on the library shelves but I'm not going to count down the days to the next one.

Cold iron, the protocols of magic suggest, is a disruptive influence on magic. Old cold iron is even more disruptive. Hence, the title Cold Iron Task refers to needing cold iron to accomplish a task. In this case, procuring the cold iron is fundamental to protagonist G. G. Grimsby discovering more about his past and vital to being able to help Rayne evict the unwelcome tenant lodged in her being. And unlike the second volume in the series, Long Past Dues, Cold Iron Task has pacing and characterization which makes for a significantly better reading experience.

Oh, Grimsby is still a “loser” with a capital “L” in many ways. He even confronts himself with being a loser, with being weak. But somehow, in the midst of that weakness, he perseveres enough and delves deep enough into his inner strength to overcome an avalanche of reversals—sort of, provisionally, beyond the odds, and with intriguing consequences. Better yet, Grimsby hasn’t lost his belief in the goodness of human and unorthodox nature, even when it puts his own well-being at risk. He is clearly the kind of underdog many of us enjoy rooting for.

Extremely interesting in Cold Iron Task are the new revelations about “The Huntsman” and his background. Les is finally showing more emotion under his rigorous demeanor and exacting standards. It adds another dimension to the character and makes him even more interesting when his relationship with others who have that role. And, although it is relatively miniscule compared to the scenes with Les and Grimsby, Rayne plays a strategic role in terms of both the MacGuffin for the adventure, the ensuing complications, and a significant turning point in one encounter.

Cast Iron Task is certainly the best of The Unorthodox Chronicles for my taste. The pacing is just right in that Grimsby really does take front and center more than in the other novels. The characters seem more real. The revelations are spaced out just far enough to tantalize but not to frustrate. The action scenes are clever and satisfying. The snark is welcome from expected and unexpected directions. I am extremely interested in seeing where this goes.

If there's one thing I love in urban fantasy, it's a good mentor-mentee relationship, and Cold Iron Task delivers that in spades. At the heart of this book—and really, the entire series—is the dynamic between the well-meaning but occasionally hapless Grimsby and his grizzled, world-weary mentor, Mayflower. Their partnership's brilliance is in how they've begun to shape each other. Once content to drown his regrets in work (or a bottle), Mayflower is slowly learning to confront his past. At the same time, Grimsby has gained both confidence and a sharp edge that wasn't there before. He's no longer just the scrappy underdog; he's stepping into his power, and I loved watching it happen.

Grimsby's growth is one of my favorite aspects of this book. His development feels natural, not rushed, and completely relatable. He's starting to take ownership of his abilities, stand his ground, and dig deeper into his own history—all while navigating the ever-evolving push-and-pull of his relationship with Mayflower. And speaking of that relationship, it's everything I want in a mentor-mentee dynamic: full of begrudging respect, exasperation, and (underneath it all) genuine, if gruff, care for one another. Grimsby's journey is one that many of us can see ourselves in, making his character all the more compelling.

Beyond the character work, Cold Iron Task is packed with everything that makes an urban fantasy shine: magical heists, shifting allegiances, high-stakes action, and twists that keep you on your toes. But what keeps me returning isn't just the magic or the action—it's the characters. I care about Grimsby and Mayflower. I want to see where they go next, how they continue to grow, and what chaos they inevitably find themselves in. The urban fantasy elements in this book are not just entertaining, they're downright captivating.

James J. Butcher, if you're listening, please make this a long series. I want to watch Grimsby and Mayflower evolve for years to come. The thought of their future adventures is something that fills me with anticipation and hope.

Now in book three of Jame's the younger's series, he's starting to develop his pacing and the universe seems to feel more organic to the story telling. James's voice reminds me of his father's early work - which is a good thing. His tone conveys a since of humor, and he is developing an art for creating endearing characters.

Most importantly this story moves along pretty well with a good plot and mystery driving the pace. James sprinkles in character development along the way, but he doesn't bog things down with a lot of whining and self doubt.

In Cold Iron Task we learn bit more about Mayflower. Previously we were told he was "The Hunter", but we had now idea what that meant. In this story we learn that is "a hunter", and there exists a clan of "hunters" that he has broken from at some point in the past. We learn more about Mayflower's deceased wife and discover that he had a child.

We also learn more about the corruption within Grimsby's agency, and discover that the fire that killed Grimsby's mother and maimed his hand was intentionally set, but we don't get enough back story to learn why his mother would have been targeted.

Cold Iron Task's plot follows two parallel threads that expose a coven of witches within the agency, and the clan of hunters at odds with the supernatural beings. Mayflower's dept to a dying friend requires him to work with hunters from his previous life. Their investigation collides with a side job Grimsby has taken to try to free Rain of her curse. It turns out their two projects are both part of the same conspiracy by the coven to retrieve an ancient artifact.

Cold Iron Task, by James Butcher, is the third entry into the Unorthodox Chronicles. The story continues with Grimsby, a junior auditor for the Department of Unorthodox Affairs, and his Huntsman partner, Mayflower, as they are entangled is a series of seemingly unrelated adventures that are not what they seem at first glance.

I liked that this book felt very connected to the two previous books, with the plot points stemming from the repercussions of the last book and several important reoccurring characters. I enjoyed the relationship between Grimsby and Mayflower being more than antagonistic and the two actually relying on each other. I appreciated how the three separate storylines converged at the end of the book rather deftly (and I’ll give myself kudos for predicting a reveal at least 5 pages before it occurred). The ending had a great payoff moment too - .

For better or for worse, the book’s pacing is relentless. On one hand, that made the book a page turner. On the other hand, all of the events of the book wrap up in the span of perhaps 36 hours? I found myself wondering at some point if the characters ever sleep, and was quite gratified when Grimsby did take a nap at some point. I wonder if the story could have been plotted differently to slow down the pace.

Overall, a fun book and I’ll snag the sequel whenever it comes out too. It fills that urban fantasy void in my heart.

This is a review for the audiobook version.

As much as I liked this story, I did struggle a bit with the reader. He wasn’t bad, he did a nice job portraying the characters, but for some reason I just never jibed with him. But that’s ok because I was able to split my time between the audiobook and the physical book. I really liked the story that included some new characters and some older ones from the other books.

Grimsby continues to be a really solid character that shows a lot of growth in this story. He still has a tendency to get in over his head and often finds himself being used by others, but he really does have a kind heart and avoids violence when he needs to. Mayflower, his older partner, is always getting Grimsby out of trouble. But I did like that we learned quite a bit more about his history and life than we have in the other books.

The plot in this one was pretty complex, but the pacing and the writing were well done so that I was easily able to keep track of what was going on. The world that was created in the first two books continues to be expanded and you learn something new about it in all of the books.

You really do need to start at the beginning of this series though, don’t jump in with this one. The first book, Dead Man’s Hand, is where you want to start if you are interested in starting this series. A great urban fantasy series set in Boston, with a great cast of characters, excellent world building and complex stories. A must read for urban fantasy readers.

In the third book in The Unorthodox Chronicles Cold Iron Task, James J. Butcher has given us a fast paced and complex story. As the world slowly unfolds, the characters of Grimshaw and Mayflower deepen their friendship but also become increasingly more multi-faceted. Each faces struggles unique to their world and the world of The Unorthodox Chronicles gets more fascinating.
From the very beginning, the action is fast paced and doesn’t let up. Grimshaw and Mayflower deal with the complications and secrets from other parts of their lives in the matter of a couple days but nothing about the story itself feels rushed. James J. Butcher builds up the suspense and the entanglements with increasing skill and sets up the new and old horrors perfectly. The mysteries that Grimshaw faces and secrets he learns not just about his own past but about Mayflowers add complexity to the world and help both characters to grow. I love how the various plot lines come together and how the solutions might be worse than the original problem. And the ending will leave readers intrigued and ready for more.
If you like fast paced and complex urban fantasy novels, with a struggling witch and a morally grey huntsman, you will love this book, especially if you’ve read the first two. The ending left my appetite whetted for the next book and I think most fans of the series will love how much the characters have grown.

Cold Iron Task is the third book in James J. Butcher's The Unorthodox Chronicles, and I am really enjoying this series. I highly recommend starting from the beginning, as each book builds on the last. The world and characters have become more developed with every installment, and this latest one really delivers.

In Cold Iron Task, we follow Grimshaw Griswald Grimsby, a novice auditor for Boston's Department of Unorthodox Affairs. He and mentor, Mayflower's growing partnership is one of my favorite parts of the story. They make such a great duo, and I liked seeing this relationship evolve. Grimsby still has a lot to learn after his first case in the previous book, but his earnest efforts are so endearing so it’s hard not to root for him.

The story kicks off with action right away, and I was hooked from the start. The pacing is fantastic, keeping me fully immersed in a world filled with magic, secrets, demons, and twists I didn’t see coming. It’s such a fun and exciting ride!

I also listened to the audiobook, narrated by James Patrick Cronin, and he was fantastic. He really brought the characters to life and made it easy to keep track of all the intricate details. His narration was clear and engaging, which added so much to the overall experience.

Overall, Cold Iron Task is an amazing addition to this magical series, and I am looking forward to what comes next.

Book was pretty good. Finished it in 2-ish days.

Was great to see Grimsby, Mayflower, and Rayne (along with others) again in this latest installment. There were also some newly introduced characters that were pretty fun as well. In my opinion, this series' likeable characters with understandable motivations, is was makes this series stick-the-landing during its more emotionally powerful scenes.

I didn't do a series reread - so there were a few characters and events I'd completely forgotten. While it wasn't too much of a detriment - it took a little longer into the text to begin to have enough context to recall them.

Also loved how we got more info on Grimsby and Mayflower backstories. Really excited to see more of that.

Overall, another easy to read easy to love book from James Butcher. I look forward, as always to the next one!

This series has really grown on me. It helps that the characters within have grown and now have a relationship based on a respectful working relationship. This book seems to have addressed most of the loose ends from the first two books. You learn a lot more about The Huntsman and a bit of Grimsby's backstory. Mostly it's a pretty straightforward mystery. As with many mystery books I've read there are two simultaneous storylines that had me wondering when they would intersect. One of them is a heist, although it thankfully avoids most of the annoying tropes - especially the crew assembly. Most of the crew is already pre-assembled and there was just need for one more. Like any good mystery, I saw some of the twists coming (the author had laid the bread crumbs) and others were just beyond my reach, but not out of left field.

There were two long-standing storylines that did not get a resolution, but did get forward momentum. Interestingly, both of them have the potential to be series-ending storylines, but could just as well be resolved in another book or two.

Overall, Butcher has me hooked. He's created a world as compelling as the one his father created (Dresden Files) and I will definitely keep an eye out for the next entry.

Grimsby is just not having a good year. One friend locked up in the Asylum. One not talking to him (and booby trapping his house). And Mayflower? Well, Mayflower is The Huntsman. You never know where you stand with him. Luckily, Grimsby is Grimsby - stubborn to a fault and always ready to do the right thing, even if it kills him. He sets out to right all the wrongs that led him here, but that's going to require help. Put in touch with the eccentric Keen, Grimsby is made part of a small team to find an artifact that just might have the answers to put things to right, but just because they all have the same goal, doesn't mean they're all willing to share. With Rayne locked up and The Huntsman dealing with his own loss and ghosts of his past, Grimsby sets out on a heist from the Elsewhere itself, providing they don't get caught by the 500 foot "guard dog". When the team betrays him and leaves him to die, Grimsby has to rely on the only thing he has in excess, pure stubbornness. There are so many other subplots and twists that I can't go into without revealing spoilers, but they're all so expertly weaved together that this book never feels unwieldy or jarring. Almost 500 pages and I finished it in 4 days (would have been shorter, but I have a job :D ). Can't wait for book 4.

3.5/5. Its feels like its been a long time since I last read book 2 but its really easy to jump back into this world and get straight back into the main characters lives. Grimsby has come a long way from the first book and is a fair bit more dependable then he was and its nice to see how he and Mayflower are getting along. Sadly for me it seemed like the two well apart and doing their own thing for what felt like a lot of the book. I'd hoped for more traditional cop-partner like stuff but it still worked when they did get together. The tone was a lot more serious and the ramifications from past book events and in some cases before the books were popping up and I'm glad that things hadn't been swept under the rug and ignored or magically fixed with little explanation. Although I hate to do a comparison to it, consequences and the fallout were constantly seen in the Dresden Files, and I'm glad that this author didn't shy away from doing it as many authors tend to skip over this or backtrack entirely. The ending was unexpected but at the same time not and we're finally given a proper glimpse of the man Mayflower had been many years ago. I look forward to reading the next book.

Well dang, that was pretty good.

Definitely broke the mold compared to previous outings with Grimsby. I was worried that it would be a recurring thing that It was good to see Grimsby taking his destiny in his own hands and learning to wield what power he has better.

I liked Mayflower's arc here too. Especially the revelation that . That really shed light his past and on why Mayflower does what he does. And the addition of Brass and his relationship with Mayflower made for an interesting way to give hints about Mayflower's past character and actions.

And this book opens up more a ongoing plot and revelations about the world. I'm looking forward to how the play into the unfolding plot.

I finished my first book of the month! Feels good to be able to slowly get over my reading slump. Another great entry in The Unorthodox Chronicles. My favorite of the bunch as of right now. James J. Butcher is living up to his dad's legacy of great stories. He managed to create a world that feels alive with mystery and danger. A constantly evolving thread of secrets. Somehow answering long standing questions while opening up new ones with no regard for our agonizing need to know more.

I'm excited to see where things will go. Cannot wait for the next installment and will be picking it up as soon as it comes out fans of urban fantasy will thread familiar grounds but in a wonderfully vibrant way. It's impossible to dislike the dynamic duo of Grimsby and The Hunstman. It doesn't feel likes there's q whole lot of new and innovative ideas in this series, but that's not necessarily a bad thing. Sometimes, we want something family and a darn good story. This series is both of these things. If you crave a Dresden Files alternative or want something while waiting for the next book this is it!

Huntsman Mayflower and Grimsby find themselves in more trouble, each going their separate ways to deal with what they both see as personal issies. Mayflower needsto help another Huntsman from Boston, other Huntsman that are not allowed in Mayflower's city, to find his younger brother who fled to Boston. Grimsby is set to help Wudge find his door, since the imp keeps making life at home hard from Grimsby., and find a way to save Rayne from the entity now bound to her and the mysterious nail that messes with magic. They have to do the work for the Department still and skirt around the rules. The story is action packed from start to finish with new secrets being revealed about Grimsby and Mayflower as the story unfolds. Old enemiers rear their heads as new enemeies emerge from the shadows. Wonderful worldbuilding. The magic winthin Grimsby grows as he learns more. from enemies, his history, and friends. For those that enjoyed the first two books. this is heartfelt, nuanced continuation of the series. I can't waiit to get my hands on book four.
